I agree w the above r.e. lsd/shrooms .. never done dmt tho.. not particularly interested. I've done salvia which I've been td is like a super light version of dmt, and was not a big fan.. thought at least salvia is only about 15 minutes :D lots of ominous dread.
Check out erowid if you want some high dosage lsd stories. In the early 90s I encountered some "mop up" doses that were claimed to be in the 3000 mic range. I tried them twice.. first time during the Rodney king riots in SF (took half a mopup, started out really fun then devolved into a nightmare. Hid in the garden of a high end restaurant, literally inside a bush, watching the mayhem unfold on market Street.. Second time was while backpacking in pt Reyes and that was the best, most transformative drug experience I've ever had. I talked to a mushroom and learned a lot about my self and humanities relationship to nature.. But, at peak, I was completely disassociated. Basically blind/deaf to external reality for about 3-4 hours. I was with 3 other people.. and I think we were just rolling around in a meadow the whole time. Eventually we somehow ended up at the ocean, and the sunset brought us all to tears. In the 90s, the most commonly available doses here on the street were about 150 mics, and cost around 2 to 6 bucks. And the comedown was ugly. I've been told that cheap/old lsd, degrades into strychnine.. which is why the comedown is so harsh. On the high dose ones I did, the comedown was completely different. Nowadays I stick to the occasional couple of shrooms or a hit of molly once or twice a year. I think today I would have too much emotional baggage and ties to my consentual shared hallucination with humanity to do psychs that powerful again.
I specifically switched to juul from cigs because I knew of nicotine salts vs the type used in most vapes. Its a huge deal and has probably saved my life.
If GDP is the only metric you are going to consider, then the US and China are doing just fine. But, and i don't think this is a stretch, there may be some other factors to consider. For California in particular, i suggest you look up what percentage of the population pays the taxes the state runs on, how many of the state's population subsist on social welfare benefits, and what how much federal assistance ameliorates state debt concerns. I posit that California as a stable state is a house of cards, both economically and ecologically speaking.
