Americans and Canadians don't often see their federal politicians engage in extended conversations about cannabis. Most of them shy away from the issue altogether, or give quick, non-committal answers and avoid follow-up questions. Check out this conversation from 2013 that's been shared on social media since Liberal Leader Justin Trudeau's election win Oct. 19.

The incoming prime minister is fully - and fearlessly - engaging a Canadian voter on an issue where there's sharp disagreement. He's pro-legalization, and she's an opponent with concerns about youth and people with addictions. Even though they have opposing viewpoints, they treat each other with respect and really talk it out - very impressive in an age where most politicians seem to have pre-screened and controlled conversations with voters and constituents.
