"Lifetime classic psychedelic use was associated with a significantly reduced odds of past month psychological distress (weighted odds ratio (OR)=0.81 (0.72-0.91)), past year suicidal thinking (weighted OR=0.86 (0.78-0.94)), past year suicidal planning (weighted OR=0.71 (0.54-0.94)), and past year suicide attempt (weighted OR=0.64 (0.46-0.89)), whereas lifetime illicit use of other drugs was largely associated with an increased likelihood of these outcomes."
In my experience a lot of people with their own issues are drawn to psychedelics as a means managing their demons. In the right setting, they can be incredibly healing. However, for some people, psychedelics become a means of coping, tripping becomes their default state and reality becomes too much for them.
One of them was also a friend of mine. By the time he killed himself he was clinically insane and should have been hospitalized, sadly the services didn't get to him in time.
I realise this is about psylocibin, but I think its still appropriate here. Psychedelics are no joke.
