Terence McKenna talking about drugs in Mexico

 This clips shows philosopher and ethnobotanist Terence Mckenna giving his opinion about drugs and the human freedom to use them. According to Mackenna's view one of the biggest barriers that prevents the debate about drugs is the ambiguous  meaning attached to the word because on the one hand governments talk of the good drugs that cure people while on the other condemn the bad ones that produce hallucinations, sedations, or euphorias. He continues his argument calling for a general debate and more research.
