When President Nixon declared war on drugs on June 17, 1971, about 110 people per 100,000 in the population were incarcerated. Today, we have 2-3 million prisoners: 743 people per 100,000 in the population. The U.S. has 5% of the world's population, but 25% of its prisoners. As Senator Jim Webb once put it, Either we are home to the most evil people on earth or we are doing something different and vastly counterproductive.

If you're worried about a kid and drug use, the safest, best thing to do is individual counseling or family therapy, none of which will expose kids to more deviant or problematic peers and both of which are proven to be effective and at the very least, they won't hurt.

I think our drug laws need to be made scientifically, as best as possible, recognizing that values will always be part of that.

Do we really want to base our 21st-century policy on what the colonialist preferred at a certain time in history, not at all based on health or what the preferences of different cultures might be? That's just ridiculous.

I don't have kids, but I've often noticed when people first become parents they seem to completely forget their own adolescence and they start to, as their kids become teenagers, try to do the things that didn't stop them themselves. And I jokingly frame this as: Your brain gets wiped of those memories when you become a parent.

The thing we want for all our kids is that they be connected with a learning community and that they have strong social and familial relationships. If we can do whatever we can do to create that and to reduce bullying and to reduce the kind of pain and shame so many kids feel for so many reasons, that stuff is going to reduce drug addiction.

I know that sounds really extreme, but if you just look at the history, you will find Harry Anslinger [first U.S. commissioner of the Bureau of Narcotics] going on about satanic swing and how reefer will make black people think they're as good as white people - which to him, obviously, was a very horrible outcome. This is the basis of our drug laws.
