Wishful thinking by Mexico and the libertarians - and various states that want a new tax revenue stream.
The last thing we need is a country of stoners. That’s one of our problems now, in fact. Too many young people with fried brains.
Stoners tend to vote democrat. Therefore legalize their habit and more will start smoking openly. Fewer democrat votes. And those republicans and libertarians who take the occasional hit won’t have to worry about insane criminal penalties. Sounds like a win-win.
