My first experience was late 30s, I don’t know what it would have been like having that experience 17 or 18. I don’t know if I’d want my kids to have that experience at such a young age.
Psychedelics are profoundly strange. My before-the-experience expectations about what it would be like (having read an absolute shitload of literature and trip reports) and what it’s actually like were orthogonal.
A bad trip does equip you with a lot of confidence and resilience in yourself and your mental strength to almost get through anything. Once you’ve been through that (like seriously believing your reality is broken) a lot of other things in life seem easier.
