Vapor is rounded water particles, smoke is microscopic jagged carbon particles that cause microabrasions. Vapor can carry tobacco or cannabis oil for example and if you vape too much this can clog the lungs up with more material than it can expel with its mucous lining. Smoking however clogs the lungs up much quicker and of course causes inflammation.

They're correct. Sadly the WHO estimates that over 99% of the world lives in places with air quality in excess of safe limits. If people care about their health they should start taking a interest in the air around them and push for stronger standards. Indoor air quality is often worse then outside - so steps to improve it include getting rid of fragrance, making sure your kitchen is ventilated and encourage people to not smoking or vape around you or children. While it may seem 'boring' if you care about your health and those of others it's worth looking at ways to reduce your exposure.

Let me tell y’all something, I really wish I had him as my wife’s doctor last month. She had to get hospitalized because her oxygen levels were at 85 and would not get any higher. She was on 10 liters of oxygen and it took her three days to get her oxygen levels to at least 90-91. She is asthmatic but we have NO IDEA what triggered her asthma attack. It’s been a month and she’s still not to where she was before she ended up hospitalized. He’s so informative and kind I wish he had been there to calm our anxiety down.
honestly a huge thank you to Dr. Ravi for his excellent delivery because I’ve learned more in 15m than I have in any doc appt using every scare tactic under the Sun to shame me out of smoking. Thank you for this breakdown. 🙏
I have a lung problem where I have no diaphragm on my righ side, it only gives me 70% of my lung capacity, I just got out of covid and am presently in a severe last longing cough. This was really informative. As usual a good host.
JW how did they discover such an issue? I ask cause my lung capacity was like at 40% normal not too long ago... like did they do any internal imaging? I hope you get better soon, I had Covid in the end of 2020, and it was tough- I nearly died and it took months to recover. It's been a couple years and I feel a lot better thou. Wishing you a recovery, too.
I finally understood why all breathing exercises comprise of long , bigger exhalation than inhalation! To Build up and keep up that lung elasticity and check / ensure that the lungs are healthy
I am a pulmonolgy resident and the realest habit of a pulmonologist is that they will make you listen to lung sounds through a computer haha and I was done when the balloon was out for description😅
I appreciate this doctor clearly, calmly,explaining stuff without fake hype or attention seeking nonsense. What gives me pause is the peoples inability to google COPD, read its description, and understand it.
Dr. Kalhan, I'm a retired 40 year cardiac and pulmonary hospital based RN. Kudo's to you. You gave the absolute BEST description of Emphysema I have EVER heard! I truly mean it. Hands down! I'm going to pass that on to some of my younger co-workers still tramping the halls who like to teach like I did. :) Thank you so much. I can tell that you care deeply about your patients, and that you care that they LEARN how to care for themselves. Plus, I'm also an old COPD'r so I know these things. ;)
Back in the late 80s when I was a kid, a doctor told us that breathing wintery air would help when I got an asthma attack, if it was too soon to take another dose of my rescue inhaler. So my mom had me bundled up standing outside taking as deep of a breath as I could of the cold air. It felt like it helped. But, if its worse according to Dr. Kalhan, it maybe have just been a placebo effect then. And now that I have grown out of my asthma. I love breathing in cold air, it almost has a soothing effect.
Our docs have always told us if our kids had breathing problems, open the window and bundle them up! It is the moisture in the cold air that helps. Same reason a humidifier works to ease breathing. I may be wrong, but I believe it depends on the cause of the asthma or illness as to whether it works or not.
If you got allergy-induced asthma (like I did as a kid in the 80’s), breathing in cold air outside where most of your allegens are dead/non-existent will make you feel better. If it’s below freezing and there’s very little air pollution, all the usual suspects to trigger an attack are gone.
Oh, now I get it! When I got COVID-19 for the first time, I was very sick for two weeks. Yet it wasn't until after the infection was gone, that I had to go to the hospital a couple times. On that second hospital visit, the nurses and doctor were suddenly nervous and rushing around, because the instruments said I had a dangerously low blood oxygen level. Lucky for me, they scanned and found that my lungs were mostly ok; it was just that I had almost no circulation in my hands. So... the hemoglobin in my hands' blood vessels was sluggish, moving less oxygen, more slowly than usual, making it look like my whole body was not getting enough oxygen; but my essential systems were still in reasonably good condition, for someone who'd endured what I just had. My body was just triaging its resources, meaning the medical instrument gave a misleading idea of how I was doing overall. And now I understand how that happened. It feels satisfying to understand this now. Thank you, Doctor.
Covid is scary. I'm rather young but it nearly killed me, and this was a good year after my asthma was well-controlled. I would be dead if I hadn't decided to go to the ER for a nebulizer or something, and then them finding my BP dropping.
Chronic weed smoker (no cigs) . I have all the bad symptoms :( . My dad used to say, "Anything you breathe that isn't air, isn't good for your lungs." Smoking effects everyone differently, some may smoke all their life and nothing happens. Then you have me.

Second opinion: go see an allergist and see if you're a good candidate for allergy shots. I've been getting them for two years, it's been life changing.
I absolutely love these videos. The things he discusses remind me of when I used to be a medic and makes me miss that occupation 😢. Also, I say this often, but I wish I had someone to share videos like this with who would genuinely take an interest
It was interesting to hear him mention that young women often get lung cancer despite never smoking. I'm 23 and I had a bacterial infection in my lungs last year. I'm recovering well, but there seems to be no explanation for how I got it!
people are not supposed to be vaporizing vitamin e acetate though, which is the only chemical positively correlated with vape induced lung injury. it was put into black market THC vaporizer cartridges because it visually looks like THC oil, but otherwise provides no useful benefit to the product. vitamin e acetate disrupts the lung surfactants and causes the injury, but regular vaping has never been shown to do that.
Indeed. Vit E acetate will not mix with a nicotine (PG/VG) liquid. It was ONLY ever used to cut THC oils. EVALI had nothing to do with 'ecigs' or nicotine vapes whatsoever
I was a former cigarette smoker and had terrible lungs. Id cough all day and all night and producing tons of phlegm. Switched to vapes one day and my lungs instanty became brand new. Think im like 2 years in and have had no issues so far. Still hope to quit someday but for anyone that smokes cogarettes it will save your life.
I rarely cant watch this kind if informative video for more than 5 min. I cant stop myself watching this video. So precisely he explained to the point.
Jesus Christ, I'm mid30 and this dude is talking to me like I'm a stupid 7yo!! Which is exactly the right thing to do to make me understand everything. Thanks Dr. Kalhan. 🤝
9:49 my son is a micro prem baby, he was born at 24 weeks. i always wondered how that monitor that we put on his foot could read what his saturation levels was at but never asked about it. thanks for the explanation on that. because he was born so early his lungs hadn’t fully developed so he has breathing problems and is very prone to getting sick which ends up with a couple days- a couple weeks in hospital depending on how bad he gets, most of the time it’s just bronchitis, but he has had bronchitis, bronchiolitis and RSV which landed him in hospital for 3 and a half weeks. he’s a fighter and is 10 months old now slowly getting stronger.
@Dr Ravi - there was a study in Canada that suggests that accuracy of the pulse oximeter depends on your ethnicity. So - as you mentioned - the sensor is based on infared light, so those with dark skin actually got incorrect readings about blood oxygen levels. So, for those in the medical community, it is important to be aware of that study.
12:56 Cardiologist here. With all due respect, the heart sits in the center of the chest but protrudes to the left. It never just sits on the left. That would only make the left lung unbalanced to the right one and potentially cause a collapsed lung later in life
People may not know they're allergic to cats until they get one. And sometimes, allergic can just develop. People who weren't allergic before become allergic.
@@just_some_bigfoot_hacking_you he’s saying the question was “what does a capers lung look like” so they probably wanted to know if there is a baseline change in a capers lung when they aren’t sick
Couple of quick things. As he mentions, the reason oxygen goes in to the blood and carbon dioxide goes out of the blood is diffusion because of the difference in concentration. The gasses want to equalize. Secondly, the hemoglobin has an affinity for carbon monoxide as well as oxygen.
5:59 i first had a feel of the lung when I aided with autopsy for the first time. It was so unique I can never forget the feel, it is spongy but crisp, like your popping thousands of mini bubbles but smooth to the touch. If you're curious, buy fresh cow/pig lung
I actually found this one really intriguing. He explained everything so well. The questions were also really good too! Hope To see more people like him.
It’s astounding that somewhere there’s a kid/adult out there who took the time to type a question about the basic definition of COPD, only to wait for a response days/weeks/months in the future, when all he had to do was type the exact same thing into google for an immediate answer to his question. The amount of effort taken to avoid the effort of reading and learning boggles the mind
There's another big source of lung cancer in the Midwest...a portion of it is called 'the cancer belt' because of it. Some of it is radon in basements, but also because of all the farming people end up inhaling particulates like dust and plant matter, as well as herbicides and pesticides. My grandfather died of lung cancer and never smoked a day in his life. It was the farming.
We've got radon in my area as well. A radon mitigation system is literally thousands of dollars to install, so I guess folks will just go on getting cancer because we can't afford not to.
@@cbpd89There are cheaper mitigation methods than hiring overpriced specialists selling dedicated machinery . One common technique is to ventilate the basement to the outside so the Radon blows away instead of seeping into the living spaces and staying around all day .
The thing I learned with all these videos is the amount of people on Twitter who apparently can't ask a question with a proper sentence and grammar, or without being rude.
I love how he is not even a single millisecond delivering the feeling of him thinking "what kind of dumb question is this". He just goes to the level of the question asked and explains it really well.
Just had 2 thoracotomies last year. Lungs rapidly filled up with fluid. Tested for everything they could think of. Only thing that hit (and just barely) was histoplasmosis. 2 months in the hospital, 7 drain tubes, 2 thoracotomies, and a bunch of tests. Also drained about 1.5liters of fluid off of my heart, too. Still not back to "normal" 1 year and 3 months later.
Re: the section on ai helping with cancer My mom had copd and had a couple tiny spots in her x-rays that doctors wrote off as scars due to her COPD About a month before she died we were back in the ER for her breathing & the ER doc said they noticed a slight change in one of the scars. One biopsy later and it was confirmed cancer. She had the tumors for YEARS with no change in them, and they were so small that further tests showed the biopsy had fully removed one small tumor. Because she was 77 and very much in the end stage of COPD the oncologist told us "well, bad news is it is cancer but we can not treat it because of your health. The good news is it's so slow is growing it won't kill you" That was the beginning of December. She was gone the 6th of January.
My mother got lung cancer at 35 and passed away in few months. We only found out about it when she was severely ill already. Very young, healthy, never smoked at all. But I guess she was just very unlucky.
Animal bodies are just like pure magic, cannot even grasp how amazing and well thought they are, i mean just imagine every single cell has a purpose for themselves and to entire body altogether . Just amazing.

"Vaping", applied to cannabis, is just as likely to refer to vaping pure flower, not juice cartridges. Vape kits for bud like the Pax 3 and Volcano are very popular. I'd love to see an actual answer to the "vape vs combust" question, since I use a lot of flower personally for epilepsy, but everywhere I look I see the same outdated info that only addresses vape carts, as if vape pens & rigs that use raw flower don't exist.
try Level tablets, they metabolize differently than edibles and give you a smokers high. I dont vape flower anymore due to finding these, game changers.
Hello, fellow epileptic here. Try switching to a sublingual oral spray that goes under the tongue so you risk no lung damage and receive the medication better. Sublingual cbd oil works instantly in a few minutes and you can drive and not test THC positive ever. I get mine at cbdforlife and it's the only thing that prevents my seizures.
I whole herb vap as well with a vapor brothers ceramic heater and a hydrator(bubbler). What is critical here is to try to use organic herb devoid of pesticides and other contaminates. I do not like to smoke anything anymore. Carcinogens are released when something is burned.
I don't smoke or vape, or do any drugs really. But when I had COVID-19 I had that wheezing and crackling. It was genuinely painful and scary I felt like I was going to die. Don't do drugs kids. It will hurt you for life.

Let me tell y’all something, I really wish I had him as my wife’s doctor last month. She had to get hospitalized because her oxygen levels were at 85 and would not get any higher. She was on 10 liters of oxygen and it took her three days to get her oxygen levels to at least 90-91. She is asthmatic but we have NO IDEA what triggered her asthma attack. It’s been a month and she’s still not to where she was before she ended up hospitalized. He’s so informative and kind I wish he had been there to calm our anxiety down.
🫂🫂🌈
honestly a huge thank you to Dr. Ravi for his excellent delivery because I’ve learned more in 15m than I have in any doc appt using every scare tactic under the Sun to shame me out of smoking. Thank you for this breakdown. 🙏
Doctors are fictional. You thank for my human slaves?
I have a lung problem where I have no diaphragm on my righ side, it only gives me 70% of my lung capacity, I just got out of covid and am presently in a severe last longing cough. This was really informative. As usual a good host.
JW how did they discover such an issue? I ask cause my lung capacity was like at 40% normal not too long ago... like did they do any internal imaging? I hope you get better soon, I had Covid in the end of 2020, and it was tough- I nearly died and it took months to recover. It's been a couple years and I feel a lot better thou. Wishing you a recovery, too.
You have lung fiction?
man, i love this guy. lol really informative without being at all condescending. so friendly and genuine-seeming.
I am now breathing manually
thx now I am too
I have never seen anyone so excited about talking about lungs! This physician is awesome.
I finally understood why all breathing exercises comprise of long , bigger exhalation than inhalation! To Build up and keep up that lung elasticity and check / ensure that the lungs are healthy
The way he explain everything so easily is amazing 👍
His energy is contagious, his passion is infectious.
I am a pulmonolgy resident and the realest habit of a pulmonologist is that they will make you listen to lung sounds through a computer haha and I was done when the balloon was out for description😅
Such a trustworthy and straightforward doctor
This was amazing. I could listen to this doctor talk all day and would never get bored. So charismatic.
This guy is super likeable. I hope he is in education; i bet students love his courses. Thanks!
I appreciate this doctor clearly, calmly,explaining stuff without fake hype or attention seeking nonsense.
What gives me pause is the peoples inability to google COPD, read its description, and understand it.
Dr. Kalhan, I'm a retired 40 year cardiac and pulmonary hospital based RN. Kudo's to you. You gave the absolute BEST description of Emphysema I have EVER heard! I truly mean it. Hands down! I'm going to pass that on to some of my younger co-workers still tramping the halls who like to teach like I did. :) Thank you so much. I can tell that you care deeply about your patients, and that you care that they LEARN how to care for themselves. Plus, I'm also an old COPD'r so I know these things. ;)
Back in the late 80s when I was a kid, a doctor told us that breathing wintery air would help when I got an asthma attack, if it was too soon to take another dose of my rescue inhaler. So my mom had me bundled up standing outside taking as deep of a breath as I could of the cold air. It felt like it helped. But, if its worse according to Dr. Kalhan, it maybe have just been a placebo effect then. And now that I have grown out of my asthma. I love breathing in cold air, it almost has a soothing effect.
I have asthma and I love the cold air. I have way more trouble with hot and humid conditions. So I guess it depends on the person.
Our docs have always told us if our kids had breathing problems, open the window and bundle them up! It is the moisture in the cold air that helps. Same reason a humidifier works to ease breathing. I may be wrong, but I believe it depends on the cause of the asthma or illness as to whether it works or not.
If you got allergy-induced asthma (like I did as a kid in the 80’s), breathing in cold air outside where most of your allegens are dead/non-existent will make you feel better.
If it’s below freezing and there’s very little air pollution, all the usual suspects to trigger an attack are gone.
They maybe thought humid air, like actual mist?
Oh, now I get it! When I got COVID-19 for the first time, I was very sick for two weeks. Yet it wasn't until after the infection was gone, that I had to go to the hospital a couple times. On that second hospital visit, the nurses and doctor were suddenly nervous and rushing around, because the instruments said I had a dangerously low blood oxygen level.
Lucky for me, they scanned and found that my lungs were mostly ok; it was just that I had almost no circulation in my hands. So... the hemoglobin in my hands' blood vessels was sluggish, moving less oxygen, more slowly than usual, making it look like my whole body was not getting enough oxygen; but my essential systems were still in reasonably good condition, for someone who'd endured what I just had. My body was just triaging its resources, meaning the medical instrument gave a misleading idea of how I was doing overall.
And now I understand how that happened. It feels satisfying to understand this now. Thank you, Doctor.
Covid is scary. I'm rather young but it nearly killed me, and this was a good year after my asthma was well-controlled. I would be dead if I hadn't decided to go to the ER for a nebulizer or something, and then them finding my BP dropping.
Ik everybody watching this rn is manually breathing💀
Dammit
you b1tc.h i wasnt and now i am bcs of ur comment
YES ITS TRUE WHEN WILL I STOP 😭😭
I wasn't until your comment 💀
Nah
Chronic weed smoker (no cigs) . I have all the bad symptoms :( . My dad used to say, "Anything you breathe that isn't air, isn't good for your lungs." Smoking effects everyone differently, some may smoke all their life and nothing happens. Then you have me.
0:30: 🫁 Vaping-associated lung injury causes inflammation and fluid buildup in the air sacs, making it hard to breathe.
3:34: 🫁 COPD is a lung disease that affects smokers and is characterized by loss of lung elasticity, causing discomfort and difficulty breathing.
6:55: ❗ Breathing through the nose is better than breathing through the mouth to avoid asthma flare-ups caused by cold air.
9:43: ⚕ A lung doctor explains how pulse oximeters measure blood oxygen levels, the composition of exhaled air, the role of muscles in breathing, and the effects of smoking and vaping on the lungs.
12:54: 🫁 The left lung has an uneven number of lobes to make space for the heart, and lung cancer can be caused by smoking or radon exposure.
Recap by Tammy AI with useful time stamps =)
I wasn't sure at first whether I was going to stick around to learn about lungs of all things, but Ravi is a really captivating speaker! Part 2...?
This reinforces my choice to quit smoking! Almost 10 years
Proud of you 🎉
"If you're allergic to your cat, get rid of your cat."
I'd like a second opinion please.
Second opinion: go see an allergist and see if you're a good candidate for allergy shots. I've been getting them for two years, it's been life changing.
Buy a quality air purifier
I absolutely love these videos. The things he discusses remind me of when I used to be a medic and makes me miss that occupation 😢. Also, I say this often, but I wish I had someone to share videos like this with who would genuinely take an interest
Eat yo lungs
Just wow. What a phenomenal educator. Must be a great clinician as well. Respect!
It was interesting to hear him mention that young women often get lung cancer despite never smoking. I'm 23 and I had a bacterial infection in my lungs last year. I'm recovering well, but there seems to be no explanation for how I got it!
It’s community acquired
Do you use dry shampoo?
I thought I read somewhere that birth control increases risk, but I could be mis-remembering
Chemtrails
Cancer doesn't care if you've ever smoked or not. They like to leave that part out.
people are not supposed to be vaporizing vitamin e acetate though, which is the only chemical positively correlated with vape induced lung injury. it was put into black market THC vaporizer cartridges because it visually looks like THC oil, but otherwise provides no useful benefit to the product. vitamin e acetate disrupts the lung surfactants and causes the injury, but regular vaping has never been shown to do that.
Indeed. Vit E acetate will not mix with a nicotine (PG/VG) liquid. It was ONLY ever used to cut THC oils. EVALI had nothing to do with 'ecigs' or nicotine vapes whatsoever
I was a former cigarette smoker and had terrible lungs. Id cough all day and all night and producing tons of phlegm. Switched to vapes one day and my lungs instanty became brand new. Think im like 2 years in and have had no issues so far. Still hope to quit someday but for anyone that smokes cogarettes it will save your life.
I rarely cant watch this kind if informative video for more than 5 min. I cant stop myself watching this video. So precisely he explained to the point.
Jesus Christ, I'm mid30 and this dude is talking to me like I'm a stupid 7yo!! Which is exactly the right thing to do to make me understand everything. Thanks Dr. Kalhan. 🤝
9:49 my son is a micro prem baby, he was born at 24 weeks. i always wondered how that monitor that we put on his foot could read what his saturation levels was at but never asked about it. thanks for the explanation on that. because he was born so early his lungs hadn’t fully developed so he has breathing problems and is very prone to getting sick which ends up with a couple days- a couple weeks in hospital depending on how bad he gets, most of the time it’s just bronchitis, but he has had bronchitis, bronchiolitis and RSV which landed him in hospital for 3 and a half weeks. he’s a fighter and is 10 months old now slowly getting stronger.
I wish I could have an appointment with him. Since having Covid in December my lungs still haven't gotten back to normal.
I do wish people would differentiate between OG vaping, using a vaporizer, vs. vaping cartridges/ juice.
The differences are important.
What are the differences 👀
Vitamine E acetate
Just stop vaping nibbas
@@dorime5018 *gg 😂
The differences? None, another form of smoking. Both cause health issues and potentially death......I know
"If you're allergic to cats, get rid of your cat!" You will rip my cat out of my cold dead hands
(Excellent presentation 😂)
@Dr Ravi - there was a study in Canada that suggests that accuracy of the pulse oximeter depends on your ethnicity. So - as you mentioned - the sensor is based on infared light, so those with dark skin actually got incorrect readings about blood oxygen levels. So, for those in the medical community, it is important to be aware of that study.
They need create a table with correct data and oximeter data combined with skin color and calculate corrections for skin color.
12:56 Cardiologist here. With all due respect, the heart sits in the center of the chest but protrudes to the left. It never just sits on the left. That would only make the left lung unbalanced to the right one and potentially cause a collapsed lung later in life
“Get rid of your cat.” 😂 He woke up and chose violence. But the question is, if you have cat allergies, why do you have a cat?!!!
I have cat allergies and have a cat. There are ways to go about it.
@@Stephanie_Vincent Don't get rid of your kitty 😿
Get scuba gear and pet 'em 😸
I have 2 dogs I’m allergic to 😅. Sometimes you may love animals even when your immune system doesn’t.
We can't always choose who we love.
People may not know they're allergic to cats until they get one.
And sometimes, allergic can just develop. People who weren't allergic before become allergic.
Love it. Please do one of these for every organ in the body.
He so expressive, and the way he speaks make me laugh, but he definitely knows how to break things down for people, and uses very good analogies
This guy is awesome - I love the way he reads everyone's questions!! I love all the passionate nerdy geniuses in the world
This is one of those rare videos I could watch without getting distracted for a second. WTG, Dr. Kalhan.
Dr. Ravi's analogy game is on point. Thanks for the educating.
Your first answer begs the question of what a lung without that unlucky vaping-associated lung injury looks like? Any chance you could do a follow-up?
Was wondering the same thing “hits vape”
Didn't he already show what an x-ray of normal lung looks like?
Rewatch the video, he literally showed an xray of non-smoker lungs... You high?
@@just_some_bigfoot_hacking_you he’s saying the question was “what does a capers lung look like” so they probably wanted to know if there is a baseline change in a capers lung when they aren’t sick
Hehehehehe. Rewatch stoney
Couple of quick things. As he mentions, the reason oxygen goes in to the blood and carbon dioxide goes out of the blood is diffusion because of the difference in concentration. The gasses want to equalize. Secondly, the hemoglobin has an affinity for carbon monoxide as well as oxygen.
And you will have a good pulse oximetry reading with carbon monoxide poisoning 😱
yep, as well as it having a 250 times higher affinity for CO than oxygen
Lungs function a bit like gills on fish, but optimized for exchanging oxygen with oxygen-rich air instead of oxygen-rich water .
Chemistry. Different number of bonds and co2 has a stronger chemical bond so is less reactive hence it being used to extinguish fires.
This guys enthusiasm for peoples deadly/harmful health symptoms made my night man.
5:59 i first had a feel of the lung when I aided with autopsy for the first time. It was so unique I can never forget the feel, it is spongy but crisp, like your popping thousands of mini bubbles but smooth to the touch. If you're curious, buy fresh cow/pig lung
I actually found this one really intriguing. He explained everything so well. The questions were also really good too! Hope To see more people like him.
As a respiratory therapist, this Dr is a breath of fresh air.
..Ok I’ll see myself out lol
It’s entirely too bad that the comment at the top of the pile is someone else making this joke 11 days before you.
So you're a respiratory therapist and an optician?
wow, I just learned more in 15 minutes than I did in 4 years of highschool. I could listen to him talk about lungs all day 😂
It’s astounding that somewhere there’s a kid/adult out there who took the time to type a question about the basic definition of COPD, only to wait for a response days/weeks/months in the future, when all he had to do was type the exact same thing into google for an immediate answer to his question.
The amount of effort taken to avoid the effort of reading and learning boggles the mind
I like the way this doctor speaks, it’s so clear it’s as if he’s a family guy version of himself. Very easy to listen to and keep paying attention to.
There's another big source of lung cancer in the Midwest...a portion of it is called 'the cancer belt' because of it. Some of it is radon in basements, but also because of all the farming people end up inhaling particulates like dust and plant matter, as well as herbicides and pesticides. My grandfather died of lung cancer and never smoked a day in his life. It was the farming.
We've got radon in my area as well. A radon mitigation system is literally thousands of dollars to install, so I guess folks will just go on getting cancer because we can't afford not to.
Yes, I believe non Hodgkins lymphoma is caused by pesticides.
Histoplasmosis too
@@cbpd89There are cheaper mitigation methods than hiring overpriced specialists selling dedicated machinery . One common technique is to ventilate the basement to the outside so the Radon blows away instead of seeping into the living spaces and staying around all day .
I live in Wisconsin, now I’m worried. 😂
The thing I learned with all these videos is the amount of people on Twitter who apparently can't ask a question with a proper sentence and grammar, or without being rude.
This guy is fantastic! He needs another video for sure
I love how he is not even a single millisecond delivering the feeling of him thinking "what kind of dumb question is this". He just goes to the level of the question asked and explains it really well.
This man needs his own TH-cam channel!!
It's so nice when you have a real teacher and expert explaining you something, rather than these wannabe annoying youtubers.
His knowledge is breathtakingly good
Vaping vs. Smoking question is at 12:00
thank you
❤❤
My answer to smoking vs vaping: Don't do either of those things! You're damaging your lung tissues!
I can breathe easy knowing this doctor has answered so many questions about our lungs.
Just had 2 thoracotomies last year. Lungs rapidly filled up with fluid. Tested for everything they could think of. Only thing that hit (and just barely) was histoplasmosis. 2 months in the hospital, 7 drain tubes, 2 thoracotomies, and a bunch of tests. Also drained about 1.5liters of fluid off of my heart, too. Still not back to "normal" 1 year and 3 months later.
Re: the section on ai helping with cancer
My mom had copd and had a couple tiny spots in her x-rays that doctors wrote off as scars due to her COPD
About a month before she died we were back in the ER for her breathing & the ER doc said they noticed a slight change in one of the scars. One biopsy later and it was confirmed cancer.
She had the tumors for YEARS with no change in them, and they were so small that further tests showed the biopsy had fully removed one small tumor.
Because she was 77 and very much in the end stage of COPD the oncologist told us "well, bad news is it is cancer but we can not treat it because of your health. The good news is it's so slow is growing it won't kill you"
That was the beginning of December. She was gone the 6th of January.
I am sorry for your loss and thank you for spreading awareness around the disease!
The way he explained COPD using the example of a balloon and a plastic bag.... Brilliant!
as a medical student this was fun to watch :) great video
0:48 really cool how this comes down to entropy
Top marks to Dr Kalhan. Clear, direct, accessible, stimulating, enlightening, educating.
👏👏👏👏👏👏👏👏
This was surprisingly very enjoyable, and very informative.
All their videos are
My mother got lung cancer at 35 and passed away in few months. We only found out about it when she was severely ill already. Very young, healthy, never smoked at all. But I guess she was just very unlucky.
Check your radon levels.
My cousin, she was around twenty. Found out too late also. So sad.
asbestos induced?
This video got me manually breathing. 😂
Animal bodies are just like pure magic, cannot even grasp how amazing and well thought they are, i mean just imagine every single cell has a purpose for themselves and to entire body altogether . Just amazing.
Need him explaining more. He explains so well 👍🏻👍🏻
thank you wired, im trying to quit vaping right now so it helps
Good luck 🤞
why, dr doesnt state any facts, shows some xray and attributes to vaping, but why. i vape alot, lungs are clear, dr's never ever said they sound bad or congested, was a smoker and dr's always had commented on my breating, not anymore

So well explained. Thank you! Very informational without being boring.
"Vaping", applied to cannabis, is just as likely to refer to vaping pure flower, not juice cartridges. Vape kits for bud like the Pax 3 and Volcano are very popular. I'd love to see an actual answer to the "vape vs combust" question, since I use a lot of flower personally for epilepsy, but everywhere I look I see the same outdated info that only addresses vape carts, as if vape pens & rigs that use raw flower don't exist.
try Level tablets, they metabolize differently than edibles and give you a smokers high. I dont vape flower anymore due to finding these, game changers.
Grow ur own stuff so much better tbh
Hello, fellow epileptic here. Try switching to a sublingual oral spray that goes under the tongue so you risk no lung damage and receive the medication better. Sublingual cbd oil works instantly in a few minutes and you can drive and not test THC positive ever. I get mine at cbdforlife and it's the only thing that prevents my seizures.
I whole herb vap as well with a vapor brothers ceramic heater and a hydrator(bubbler). What is critical here is to try to use organic herb devoid of pesticides and other contaminates. I do not like to smoke anything anymore. Carcinogens are released when something is burned.
Okay this guy is actually getting me invested in learning more about lungs
I don't smoke or vape, or do any drugs really. But when I had COVID-19 I had that wheezing and crackling. It was genuinely painful and scary I felt like I was going to die.
Don't do drugs kids. It will hurt you for life.
