This series uses visual effects and CGI and, for the first time ever, takes the viewer on an entire trip from start to finish inside the human body. With testimony from people who enjoy using the drug and those who have become addicted, the programme reveals how cannabis takes over the inner workings of the brain, creating mind-warping and heart-racing effects.

With exclusive access to cutting edge scientific research, it confronts the myths and controversies that surround cannabis, reveals whether it is addictive, if it destroys our memories and finds out if it can even lead to psychosis.
