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

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

Addiction is when you fall in love with a drug instead of a child or a lover and the learning that takes part in that part of the brain is designed by evolution to get us to persist despite negative consequences to do what we need to do - because I don't know anybody who could survive a relationship or parenting if not for the ability to persist despite negative consequences. The problem is when that gets misdirected to a drug and then you can find yourself in some very negative and potentially deadly situations.

Incarceration is as useful for addiction as it is for diabetes - i.e., not useful and potentially harmful, particularly for kids.

We absolutely should legalize marijuana.

Punishment by definition isn't going to help. So what you need to do is to help people to change and recover is to help them find different areas of passion and help them find better ways of coping. Because about 50 percent of people with addiction have a preexisting mental illness, about two-thirds have had some type of severe trauma during childhood, and they are not using to the point where they're risking their lives because it's fun. They're doing something to help them cope.

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.
