Okay, but to me, most people would say high blood pressure pills, anxiety, those are normal medications that people receive through a doctor's order whether you're in prison or not, so those shouldn't be the issue.
You seem to imply that some of the addictions in there were to legal drugs. I wouldn't think high blood pressure pills or anxiety pills are necessarily addictive. If I'm wrong, just say so. Give me examples of ones that are addictive.
