Love is great and it does help a lot of people, but a lot of people do have things like depression or schizophrenia or bipolar disorder or other disorders, all of which will need to be addressed in order for people to stay in long-term recovery.

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

In order for people to recover, we can't just say 'love is all we need.'

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

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.

Marijuana is not not harmful, but is the least harmful psychoactive substance that we have, with the possible exception of caffeine.
