This video covers the extraction, purification, and modification techniques used in the drug trade to illustrate the types of chemical evidence that will be experienced in the Forensic Chemistry lab.

CORRECTIONS:
In the video I incorrectly state that fentanyl affects the cardiac function. A commenter points out that it more intensely targets pulmonary function. This is seen in the video where the police officer comments that his lungs locked up and he could not breathe at all. His lungs locked up before he went unconscious. Narcan saved his life! https://nida.nih.gov/publications/dru...
