Has really helped me any time I start overanalyzing what’s going on and how I’m feeling. Psychedelics or otherwise. It’s just the drugs, it will pass.
So I'd introduced a friend to LSD. They liked it a lot, and wanted to trip again the next day. I advised against it, because tolerance would reduce effects.
But no, it had to be. So we took maybe twice as much, and it was still disappointing. And then, being a total dumbass, I suggested that we smoke some marijuana.
Now my friend was impressed. Indeed, they were totally panicked, and convinced that it would never end. Because their short-term memory had become maybe 30 seconds.
So I spent the next three hours saying "It’s just the drugs, it will pass."
Plenty of other drugs that have real benefits without as much potential for a bad trip. MDMA is much more my speed.
