Horizon: Cannabis: The Evil Weed?
Posted on 28th January 2009 in News
Synopsis:Cannabis is the world’s favourite drug, but also one of the least understood. Can cannabis cause schizophrenia? Is it addictive? Can it lead you on to harder drugs? Or is it simply a herb, an undervalued medicine?
Addiction specialist Dr John Marsden discovers that modern science is finally beginning to find answers to these questions. John traces the cannabis plants’ birthplace in Kazakhstan; finds the origins of our sensitivity to cannabis in the simple sea squirt; and finds out just what it does to our brains.
He meets people who have been changed by this drug in drastically different ways – from those whose lives have been shattered to those who lives have been revived.
Key talent John Marsden?
