Edit: I was not fair to Trump on this. He apparently isn't a drug warrior. Still gonna be an easy vote for me though!
(Edited to remove sarcasm. That wasn't really necessary.)
The OP is probably referring to Sanders, but Trump has said let the states do whatever they vote for.
Not just that, but Trump supported marijuana legalization as far back as 1990. That was right around the height of the war on drugs, in between "Just Say No" of the Reagan years and the anti-drug, tough-on-crime propaganda of the Clinton years.
I can't really endorse pretty much anything else Trump says, but it really can't be overstated how rare it was for anyone to be standing up for marijuana legalization (publicly) 25 years ago.
In oti's collection of quotes shows that he's personally anti-drug but believes it is a states issue.
Yep. Gary Johnson.
