Interesting. I dabbled quite a bit myself (and about 20 years ago, when there was always some crazy new research chemical like 2ce to try, as well as the standards like acid and mushrooms), but most people I know who had weed turn on them weren’t into many other drugs. They did have actual mental health issues however, and I always attributed it to that. To be fair though I lost touch with many of the people I used to trip with so perhaps that’s more common than I realize.
