Amy Winehouse's death a lesson?

I agree with all this and just want to add that another measure to help your kids to not go down the road to addiction is to address any emotional issues they might have or be developing. From my own personal experiences (wild adolescence and early adult life; have known many addicts) and from watching shows like Intervention, it seems that the truly devastating addiction stems from trauma, abuse, and/or mental health issues. The addicting drug is used to self-medicate against the pain they are feeling, rather than more positive measures such as therapy.

I guess what I want to add is that if your (general you, of course) kids are troubled, get them help before they begin a spiral of self-medication that will lead them to a possibly deadly addiction.
