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

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.

A lot of addiction actually ends by age 30 - something like 50 percent of all addictions with the exception of tobacco - and I think a lot of what's going on there is that the self-control areas of the brain are finally developed enough to be able to stop yourself from relapsing or just continuing. There is a maturational aspect to it as well.

I also had my own addiction to cocaine and heroin in my 20s. I knew that it was driven not by the things that the drug workers were telling me; in fact, I couldn't believe any drug information that was given to me by authorities because I knew from my own experience that it was wrong.

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

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.

We should not be putting kids in cages and hoping that is going to fix their psychological problems of any type.
