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.

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

Science could never get you to make alcohol and tobacco legal and marijuana illegal. Only racism can do that.

Because addiction is a developmental problem, the developmental stage is important, things like employment are important, things like having a sense of purpose, meaning and hope are important, and this is why there's been so many spiritual cures for addiction, because those things often give people a sense of meaning and purpose.

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.

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.

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.
