Sorry to tell the people who've had the hemp pulled over their eyes, but cannabis already has a long-standing culture and industry which are threatened by legalisation. Legalisation aka C45/C46 is almost exactly what Stephen Haper was proposing with C10/S10.C15; it's just being called something different now.
Legalisation empowers and enriches government and damns the people. For example, most renters will not be able to grow or use cannabis in their rental unit, not even the balcony. C45/C46 are more like Canada's patriot act. It's legislation that gives polive unprecedented, police-state like powers. Medical users are going to be denied access to forms of cannabis which were previously won by Supreme Court rulings like RV Smith 2015.
