Of course government gets involved in personal choices. Every crime committed by a person is a personal choice. Interactions between parties are interactions between people. The distinction you're trying to draw here doesn't exist.
My personal opinion is that most people won't be able to regulate any large caches of the above-commented drugs... but after one or two rides on Salvia most'll keep a wide birth [which I recommend as "the worst experience possible; if somebody suggests you try Salvia they're bullying you; try something else"].
The experience of existing for a short time without the concept of self, experiencing zero sensory filters, and finally having your brain rebooted as it has a kernel panic (and going through the brain kernel load process as it does so) is mind blowing.
It’s enough to convince you that we live in a highly advanced simulation. Or one could just be high af.
Also I’m pretty sure it was based on an old version of Linux because I’m convinced I saw the kernel message “Based upon Swansea University Computer Society NET3.039“.
QED God is a programmer. :-)
