“Very commonly substances are criminalized because they're associated with what's called the dangerous classes, you know, poor people, or working people.… Actually, the peak of marijuana use was as I said, in the seventies, but that was rich kids, so you don't throw them in jail. And then it got seriously criminalized, you know, you really throw people in jail for it, when it was poor people.”

Context: If you don't give power to the words that people throw at you to hurt you, they don't hurt you anymore — and you actually have power over those people. … So, if you can, realize that the things that people say about you — they don't really matter — it's who you are. And the older you get, the more you'll understand that — because it gets better. And people get nicer too.
