So what exactly is an acid flashback? Do you get totally messed up again like you just dropped 'cid?
When I was young and foolish I messed around with this drug and I hear people say stuff like, “You could have a flashback 50 years from now…”
I used acid roughly 25-30 times over 5 years and didn’t have a flashback. I know one or two people that have had them, though, and they describe them as very similar to the actual experience except that it only lasts a minute or two.
Nobody is positive why they occur, but the general consensus is that it’s a purely psychological phenomenon. I’m pretty sure nobody gets flashbacks for more than years after they’ve done acid. Probably a lot less than that. Here is the section on flashbacks from the LSD FAQ.
More than 5 years is what I meant to say there.
