GOP presidential candidate Gary Johnson says:

So going back to 1999, I came to the conclusion… that 90% of the drug problem is prohibition-related, not use-related. That’s not to discount the problems with use and abuse, but that ought to be the focus. So in 1999, I advocated then, I advocate it now. Legalize marijuana. Control it, regulate it, tax it.It’s never going to be legal to smoke pot, become impaired, get behind the wheel of a car, do harm to others. It’s never going to be legal for kids to smoke pot or buy pot. And under which scenario is it going to be easier for kids to smoke pot or buy pot? The situation that exists today, where it’s virtually available anywhere, and the person that sells pot also sells harder drugs? Or a situation where to purchase it, you would have to produce an ID in a controlled environment, like alcohol, to be able to buy it. I think you can make the case that it would be harder to buy it, in that controlled environment.
