You edited your answer down from 30 to 26. Which shows me you really haven’t thought about your statement at all. Aside from it being totally asinine to make a relatively harmless drug illegal for a 21 year old to use, there’s about a 0.0% chance you’d be able to enforce that. And why would you want to? If I can vote I should be able to do everything else, too.

Sincerely, a 25 year old who voted so he can legally smoke weed in Canada.
