It’s regulated quite tightly. But if you can’t shut down the illicit street drug market you aren’t going to be able to shut down the illicit make-your-life-better black market either.

I think what’s happening now is about right. FDA approval process for the vast majority of people, and make those who want to play drug astronaut biohacker find it via underground methods. No reason to crack down super hard on such folks since the societal impact is likely net positive - unlike fentanyl or what have you.

Perhaps there could be better enforcement for the folks being totally blatant about it as it risks going “mainstream” and hitting people who don’t have informed consent, but I imagine that’s coming as law enforcement catches up.
