Several chapters in Beautiful Boy refer to brain studies and evidence of addiction. He also consults with experts regarding the best treatment approaches, particularly for those addicted to methamphetamines. What are the best structures for recovery?

I think lengthier treatments and more support after treatments would be beneficial and likely crucial. I think a stumbling block is that many people with addictions do not have the family support and financial resources (and possibly intellect) that was evidenced in this situation.
Education before addiction would seem to be helpful, with more resources for coping with feelings and situations in one's life as an alternative to using substances.
