How many people have overdosed on LSD? None? I don't see why you would include LSD on this list (I may be missing the point of the list, though). I do understand a small percentage can have long-term, negative reactions. However, the mechanism for this is not well understood, and what we do know suggests many of these individuals were already at risk for mental illness. Thus, this is something that can likely be prevented with more awareness and research, to a large degree. I'm discounting "bad trips" here -- my understanding is that the large majority of people who have experienced a bad trip report learning something from the experience and don't regret it [1].
