Aren't people always talking about set and setting, after-trip integration, not taking them if there is a history of mental illness, not being on SSRIs, etc? If anyone at any time is telling people that something doesn't come with some sort of risk, they're either lying or ignorant. Especially true when it comes with the mind.
Also, reading this linked person's comment, they were on DMT and it sounds like they have some strong ideas about how the universe works (they mention having been to "heaven" before and keep mentioning hell and evil and devils as if they are real). Yes, people should be careful, especially when they have issues with mental health.
DMT is related to LSD (they're both tryptamines). I think DMT made them hallucinate those things which is why they talk "as if they are real" - that's something they felt like they genuinely experienced, which is what made it so traumatic.
As for the heaven thing, I do not know if they were particularly susceptible to delusions before ever taking anything, but if they were, then it was probably not the right choice, yeah.
Oh for sure, I'm well aware of what DMT is like and I know it's very easy to get confused by things that come up during those trips since they are so vivid, which is why integration is important. He also took 60mg, which is on the high end of a strong dose afaik.
I've wondered if it would be useful to approach psychedelics similar to the way that meditation is taught in vajrayana lineages, where you have to do preliminary mind trainings before you start advancing to other practices. If you encounter "hell" in a bad trip, like the person in the post, but have no way to understand it, it's easy to believe in it literally.
I just watched a few minutes of that video you linked and I'll definitely watch it later, he seems very lucid about his delusions, thanks!
