> LSD being the particular substance has nothing to do with it, in my opinion. I was young, dumb, reckless, and played with fire then got burned. It could have happened with any of the other dozen psychedelics I took, but it just so happened to be LSD the one time that it did.

I have a close friend who had the same experience with excessive use of marijuana, but my money would be on psychedelics being far more likely to produce the outcome you unfortunately experienced. He's much better today, but not entirely "ok".
> But I want to add, that while giving me the most nightmarish, traumatizing experience of my life, the best/most positively-profound experience has also been on the same substance. I grew up in a pretty abusive household and didn't do well forming relationships growing up, and had a lot of anger and resentment in my worldview. After taking psychedelics (LSD, 2C-B, Shrooms) and MDMA with the right group of people a few times, my entire perspective shifted. For the first time in my life, it felt like I understand how it felt to be loved, and what "love" was, and how we're "all in this together" so we may as well be good to each other while we're here.
This sounds rather similar to my friend's story.
Can Taking Ecstasy (MDMA) Once Damage Your Memory?
https://www.sciencedaily.com/releases/2008/10/081009072714.h...
According to Professor Laws from the University’s School of Psychology, taking the drug just once can damage memory. In a talk entitled "Can taking ecstasy once damage your memory?", he will reveal that ecstasy users show significantly impaired memory when compared to non-ecstasy users and that the amount of ecstasy consumed is largely irrelevant. Indeed, taking the drug even just once may cause significant short and long-term memory loss. Professor Laws findings are based on the largest analysis of memory data derived from 26 studies of 600 ecstasy users.
> (from your comment below) I took 300ug of LSD recklessly on a particularly bad day for me, in a particularly uncomfortable setting.

imo 300ug is the point where you need to have some serious experience with tripping to be able to handle yourself. because if you're coming up, the acid is already circulating your bloodstream, and you get that horrible sinking sensation of thinking you've taken too much... you're in for a really bad time if you don't know how to control the trip.
I think it's difficult to say how big a dose really is until you've had a bad trip on it. only then can you see how insidious everything can get and as such just how intense 300ug can be. the reason people say not to start on doses like that is so they will AVOID those horrible experiences. so yeah, 300ug is a large dose, just because if shit goes wrong on it then you're fucked.
