Fentanyl and dartgun myths. A biologist explains.

It is a common misconception that fentanyl can be absorbed through the skin, but it is not true for casual exposure. You can't overdose on fentanyl by touching a doorknob or dollar bill. The one case in which fentanyl can be absorbed through the skin is with a special doctor-prescribed fentanyl skin patch, and even then, it takes hours of exposure. Dart guns in movies/TV are wildly inaccurate, drugs often take 10 minutes or more to act on the body when a dart gun or blow dart is used..never instant.
