How drugs work. Part 1, Cannabis.

The first in a three-part series which uses visual effects and CGI to trace the effects of drugs on the body. This part focuses on cannabis and includes accounts from those who use the drug and have become addicted. We see how cannabis takes over the workings of the brain, creating mind-warping and heart-racing effects. Cutting edge scientific research also reveals whether or not it is addictive, the effects it has on our memories and if it is connected to an increased risk of psychosis.
