As far as friendships go things change even without the fame. People start moving on. I have a few friends that are married and are starting to have kids and I'm like 'Oh my goodness gracious - that's so insane.' I also have friends who are just doing their own thing which is cool.
Addiction should never be treated as a crime. It has to be treated as a health problem. We do not send alcoholics to jail in this country. Over 500 000 people are in our jails who are nonviolent drug users.
