I tried psychedelic mushrooms when I was younger. They basically unlock new perspectives that you probably never would have experienced otherwise, and the novelty of those perspectives makes them feel rather profound. In addition to new perspectives to experience and consider, it also tends to leave people a bit more open minded and thinking critically because the experience unto itself offers greater awareness of just how much you don't know or notice in your daily life, and to know that you don't know is powerful when it comes to ongoing personal growth. A government that wants mindless herd animals as citizens obviously won't want psychedelics to be normalized, to say the least. Obviously psychedelics need to be respected in the same way firearms need to be respected, ie you need to be responsible, safe and informed. But I can easily see how psychedelics could be healing for many people with unresolved trauma because they offer new perspectives, and people with PTSD and similar struggles are often psychologically "stuck" in one detrimental perspective.
