Cannabis legalization proponents in Canada are rejoicing in the wake of the Oct. 19 elections that gave the Liberal Party a clear majority and position its leader Justin Trudeau to become prime minister. The son of Canada's revered former prime minister Pierre Trudeau, Justin openly advocates legalization. He even admitted to Huffington Post in 2013 that he had toked since becoming an MP representing Montreal in 2008. He also revealed that his late brother, Michel Trudeau, was facing cannabis possession charges before his death in an avalanche in 1998, and that the experience influenced his position. In vivid contrast the Conservative Party's incumbent Prime Minister Stephen Harper has been leading a crackdown on Canada's medical marijuana program, and even recently called cannabis "infinitely worse" than tobacco. But how easy will it be for Trudeau to follow through on his promise to legalize?
