Geneven, I’m so sorry, I certainly didn’t mean to come off as hostile. I too have a healthy skepticism about nootropics, and I don’t see how anyone couldn’t, given (as you and sylass94 have pointed out) how little we know about the brain (and thus what crude tools these are), the borderline efficacy of many of these drugs, the dangers of overdosing, the possibility (again because we know so little) of long-term deleterious effects we don’t yet know about, etc. It’s very much caveat emptor, and I think we’re all just trying to do our due diligence and figure out how much (if any) we’re willing to experiment on ourselves, given unknown risks and possibly small or nonexistent benefits.
It’s your use of the word “scary” to characterize the youtube videos you saw that pricked up my ears, which to me suggests that someone has come upon genuinely concerning negative effects that I may not yet be aware of, but I’d really like to be. If you might be willing to share but don’t want to put yourself on the “firing line,” please feel free to PM me (and agreed, youtube URLs are a pain, but they should be in your watch history). But I guess I would argue that it would be a community service to let everyone see what you found concerning, and who cares if others are persuaded or not? We’re all adults, making our own decisions, and in an area as murky as this, each person’s assessment of risks and benefits and the balance between them will be pretty unique, and if people disagree with you, f**k 'em!
