How do you stop the overdoses?
I don't know. But the best thing that comes to mind at the time, is that maybe a lot of those who are dying were not well educated about how to use the drug. Doctors in todays world are very busy, and they don't seem to have time to sit down with their patients and educate them. This is a problem (one that i don't know how to fix), but it seems likely that there are a lot of doctors out there that just give people strong pills and tell them "take this much, no more, no less", and they just send them on their way. If the patient sticks to the dose, then they'll probably be fine, but unfortunately, it takes more than that to prevent a tragedy. I think the best thing is to somehow make sure that anyone taking any strong medication be as thoroughly educated as possible about it; including dosing and drug interactions. You can't just limit access. Those types of regulations will never work. There is no way to make drug use less dangerous except by making the only people who truly have control of the situation (the patients), as knowledgeable as possible.
