How does synthetic cannabis show up on a screening test? How does synthetic cannabis show up on confirmatory test? If the person says they have not used SC is it possible the confirmatory test is wrong or specimens were mixed up or tampered with? The same specimen is used for both test correct?
How long does it take to get down to 10ng for cocaine?
I got a positive urine test for alcohol im on zoloft, hydroxyzine, klotopin but olso had 1 sip of kabachu yea and had a drig test a few days later would that do ot and can they determine it

PlZ make videos in hormones recognize and development and hormone tumover
What about the cross projection method?
Great vid, thanks!
Will a b vitamin cause a positive result?
U made my concepts crystal clear thank you sir!
You're welcome. Have a great day!
GHB IS NOT ROOFIES..LOL, ROOFIES ARE ROPHYNOL , A BENZO
I have a question. How much of a substance is needed to accurately test a drug. Can they do it with just residue or maybe even a pill the size of a crumb?
It is possible if the sensitivity of the particular test is good enough for small quantities.
How can be test... The quality of medicine... Like .. Generic vs branded
Thank you! Nice explanation and I like the drawings.
You are welcome!
Very helpful sir..!! Thankyou
Most welcome
Is it possible to have multiple crime scene?
Yes, you can have a primary crime scene as well as secondary crime scene(s).

@@halkreitman7838 how long can they detect Cocain up to??
@@jeremiahrowley2592 2 to 4 days
@@halkreitman7838 no 2-4 days is only if you're a light user, I tested positive 10 days after last using it
@@jeremiahrowley2592 2-14 days, people are usually good within a week, but if you do crazy amounts and binge use like I did it could be 2 weeks, I tested positive 10 days after last using it
You want to take a nap or eat your breakfast first?
This helped me a lot while in police academy thank you 🙏🏿
You're welcome!
Talk so fucking slow
I wish I can just pay the labs to pass my random drug tests. I had to quit smoking weed to work at Facebook construction. Or is adultering urine easy to detect? I have my medical marijuana card and cant even use it.
So say I took a drug screen for a job and the lady said I passed and was negative for all drug but I clearly seen a positive for methadone but I go to a clinic but she said I passed for all drugs so I didn't ask but then I heard that they also send ur specimen to the lab . So what happened? Does the lab test a specimen again even though it was negative ? Why did she say I was negative when I seen I was positive for methadone? I'm confused
Well that's because you're prescribed to methadone since you go to a methadone clinic

Wow, nice powerpoint
LOL the woody woodpecker xD
If gas chrom is used and the specimen is only being tested for xyz will other compounds come up on the test when testing for xyz? Example: if mdma cocaine and benzodiazepines are being tested for will lsd come up on the test?
Geremey Martinez No. Each distinct drug compounds normally have to be extracted or prepared in a way that will only isolate the analyte of interest. Likewise when running samples through a GC, it is tuned to look for and detect whatever drug the quant method is set up for. So if a person uses cocaine, but the testing is only for THC or amphetamines, it will not be detected. Also most labs will only report what the client asked for anyways. If for some reason a wide array of test was done on a sample, but say only THC or Opiates are to be reported, than only those positives will be sent out regardless of what the other tests come up with.
A “roofie” is street slang initially applied to flunitrazepam (Rohypnol). It’s a benzodiazepine approved for use in select countries outside the US.
Wow, I didn't know a roofie, is a benzo
Sir can you please provided more videos please
Very good video sir especially for iit jee make all concepts of jee like this plz.....
I had a false positive for amphetamines I paid 50 dollars for this test. I don't use amphetamines ❗I got this test for a methadone clinic I go to. Man they better get this right because I've been clean for 5 years❗
Hey sorry to hear that @sissy pie I am a phlebotomist and now a MLT medical laboratory technologist.....I would like to know if you had been possible dehydrated? or have been exercising right before the test?... I have seen false cases on stuff like this mostly with (thc in most cases last the longest) in the blood stream as well as urine. I would suggest you drink water and eat a good meal and go to a different place and you should pass! Trying to be informative. Thank you : ML Tech Nico
I just got a positive urine recently, and I have never done anything illegal. They say they are taking away my pain meds.
Unfortunately, it is true that false-positives (as well as false-negatives) can occur and not all labs are as accurate as others. Some facilities may perform a second test or a second run-through. Qualitative tests are generally less sensitive, but they may be easier to use at point-of-care (POC) or in the field or may be used as an initial 'presumptive' test for some facilities. This means that if this first 'presumptive' test comes back as a positive for a class of drugs, for example, then they can send the sample off for more expensive, definitive drug tests whereas if the first 'presumptive' drug test comes back negative then the individual is assumed to be negative for the drugs being tested. (Please note that this last point may be more applicable for health settings or within managed health care and NOT for use within any emergency setting.)
@@daystorms I failed a test ten days after last using amphetamines, I binged use I just can't understand why all these websites say it's out in 3-5 days, I heard some cases of people failing even 14 days later
@@jakedooley5300 the only thing I can think of is that you have so much in your system that it would be almost impossible to get rid of the toxins in a short space of time.
Hard to follow, not a very in depth review. Watching this made each pattern more difficult to understand.
Thank you for this very detailed lecture. I wish you were my professor!
i have a question if you do a drug screen and it was a false positive for say methadone when they sent it to the lab would the lab just look for methadone or would they look for what caused the false positive and report that aswell?
Nate, this protocol would be set up by the lab that did the initial screening. Some labs may only report back "positives" and/or "negatives" whereas other labs may have within their screening protcols a secondary test to determine whether or not it is a false positive and what caused it.
You are somewhat correct the screen is done for reasons of record.... If there is a false positive that would have to be reported and order a new draw or sample to be testing once more ML Tech: Nico
Got it. Thank you!

I love seeing someone else with handwriting as bad as mine. Keep making great videos!
nice
This is something amazing!
Thank you so much! i learnt alot from this lecture!!
I'm not kidding, but this is the best science explanation video I've seen. Extremely clear, and on point. Amazing job, and thank you very much! Keep going, good luck!
