Drugs are bad enough without making this of kind stuff up
I first read this a few years back when I was a 9th grade English teacher (and before it had been officially debunked), and while I didn't let on to the students, I was laughing my a** off because I actually did a few drugs in my day. There is a part, for instance, where the girl becomes a prostitute because she is addicted to LSD. Whatever bad thiongs you can say about LSD (people ending up permanently in mental hospitals or jumping off buildings thinking they can fly) it is NOT addictive and has always been dirt cheap. There's also a scene where she and a friend are raped by some people who inject them with heroin. This is not totally unbelievable, but rings very false because most junkies would NEVER waste their precious heroin to get sex (except maybe a heroin dealer, but then he wouldn't need to go find innocent girls since I'm sure there are plenty of female junkies perfectly willing to exchange drugs for sex). I also didn't quite buy her "friends" being so threatened by her attempts at sobriety that they would dose her. It's not like there was any shortage of people to get high with in the early 1970's.
The students I had were young and they took this book very seriously. If it stops them from experimenting with drugs all the better. But what happens if they experiment drugs like marijuana or even hallucinogens and find out this book is a lie? Are they going to believe what people tell them about much more dangerous drugs like crack, crystal meth, or heroin? It seems like it's better to just tell the truth about drugs, which is bad enough without making stuff up.
