Yeah, drugs can really fuck up families. Yeah, sometimes things get really bad between parents and teenagers and it is a fool who thinks the answer is to start moralising about someone else's pain. I know there 'but for the grace of', go my family or other people I love.
But a book? That's just the narcissism of the self obsessed media classes. It helps no-one's pain, and spreads the family damage into the future.
P.S. Having posted this I went to bed and wondered if it was, perhaps, a bit over-personal and ungenerous. This morning however I find I am the very model of fair-minded reasonableness. Well, at least I am by the standards of potlatch.
