For fifty years marijuana has been Australia’s most popular illegal drug; seven million of us have tried it, and more than two-and-a-half million smoke it every day. Michael is Australia’s biggest public advocate for smoking Marijuana. He is ambassador for life at Nimbin’s Hemp Embassy, co-creator of Australia’s annual celebration of all things cannabis, Mardi Grass, a foundation member of the Help End Marijuana Prohibition (HEMP) political party, and a man who has smoked his own body weight in marijuana over the course of his lifetime. Kerryn is a former drug user who is now a passionate school drug and alcohol awareness educator and published author on the topic. Kerryn believes marijuana is the potential gateway to a lifetime of addiction and ruin.
