You missing the point I'm not disagreeing that the probability is low I'm argueing that 12 people is insufficient to claim it doesn't exist. Also the fact medically its not superior to the current accepted treatment options therefore in a clinic setting lsd has no use
There might be better medications for treating alcohol abuse, like you mentioned, sure, but in terms of psychiatric medicine, really there's nothing like LSD, it's quite unique. It can't really be compared to traditional medicine, which usually have no mental side effects. The emotional and psychological effects of psychedelic drugs are incredibly profound, there's nothing that will emotionally open up the mind like psychedelics.
Therapeutically they're unparalleled. Psychedelics can completely change they way you think about something, how you feel about it. They can show you the world and yourself in a completely different light. Traditional drugs can't do that. You know when somebody is closed off emotionally, you can sometimes never get through that emotional wall. Well MDMA tears it down instantly, it's unbelievable how reliably it works. But at the same time they can't simply be used like traditional medicines, where you simply write a prescription. There have to be guided sessions.
LSD certainly also has a place in cognitive science, the science of thinking. (which is a relatively new science). Again because it dramatically and reliably alters and enhances our consciousness and thinking, it's a real tool which we can use to aid our understanding of how consciousness and thinking work.
