"This is from a group making a full length documentary on the subject, but so far it has only aired as a one hour special on Candian TV. Here's a description of the film:

The film follows the story of two radical doctors and their patients. One is in Peru, and for 30 years has worked hand in hand with indigenous healers. The other is a doctor and bestselling author from Vancouver. He believes the medical system has failed us - by chasing symptoms instead of the root causes of illness. To help his patients - and benefit all of us- he is willing to risk his reputation and go up against Canada’s legal system.

We follow Dr Mate’s attempts to help his patients, and the miracles and disasters along the way. We watch young, cocaine-injecting lovers teeter on the edge, and an aboriginal single mother with a decade-long crack habit reunited with her children. Meanwhile, Dr. Mate relapses into his own addictive patterns, and is forced to face the consequences, and to learn the true meaning of commitment.

Along the road, we meet a Kurdish gangsta, a Catalonian pharmacologist, an indigenous shamanic powerhouse from the Putumayo, a shoeshine boy from Perú, and a very very angry wife. All wrapped around a mysterious visionary drink from the Amazon, outlandish rituals, purgative plants, tears, laughter, epiphanies, relapses, classical music, and the eternal human question: how to live.”
