Drugs were not regulated at all when MDMA was invented, but when Shulgin rediscovered it, drugs were at the very early stages of prohibition.

I should make this very clear about MDMA though, I think people should try it, but MDMA you should be careful with. MDMA is one of the least sustainable drugs to abuse, but the effects it can have if you abuse it, are life-long. At the very least you can lose the magic which is usually permanent.

It is definitely a state that is meant to be respected. If you want to take something similar to MDMA more often, I'd recommend 2CB although you'll have a clearer headspace on that.
