You once had all the brains! Now they’re just carpet stains!

Apparently, there could be some truth to the teachings of Reefer Madness, and CBC is delving into the mystery of whether or not pot is damaging young minds. The Downside of High, airing Jan. 28 at 8 p.m. on the Nature of Things with David Suzuki, is a documentary on the link between marijuana and mental illness. Scientists reveal that teenagers who start smoking pot before the age of 16 are four times more likely to become schizophrenic, telling the stories of three young people from British Columbia who believe (along with their doctors) that their mental illness was triggered by their marijuana use. The documentary tackles the debate that super-potent pot is a big part of the problem thanks to increased amounts of THC.

Following this documentary, Cannabiz airs on Doc Zone at 9 p.m. and tells the story of the eccentric border town of Grand Forks, B.C., nestled in the Kootenay Mountains. It was here that draft dodgers and hippies planted the first “B.C. Bud” in the 1960s. Fast-forward to today and marijuana growers find themselves at the crossroads of crime and commerce, battling for a portion of the 20 billion-dollar industry. Canadian drug laws are questioned as Brian Taylor, the “Marijuana Mayor,” and ex-convict Sam Mellace petition for legalized medical marijuana as an answer to the escalating crime and gang violence.
