In a criminal justice setting, it's very hard to create a therapeutic environment where people do feel safe, but the real important thing to do is to do your best to do that.

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 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.

I don't think there's a single child who's ever benefitted from being arrested for marijuana or for underage drinking; this does not solve the problem. It makes worse problems because a) it puts them into the system, and b) it gives them a potential criminal record to have to deal with and it can have consequences for school.

The thing about our drug laws is that they're not based on science.

A lot of the stuff that we say about drugs is just wrong.
