While I agree that I'd love to have a guarantee on purity, the way to do that is just to make LSD legal, rather than have some private equity backed pharma company tie up the supply. LSD should be a case like insulin or the polio vaccine, as it offers an immense amount of potential for the planet.

Sure, if they want to make money by offering retreats in clinical settings for people too afraid to spend an afternoon with a loved one on 100ug of LSD, by all means. But jumping through hoops to lock up the supply of a truly revolutionary molecule that could improve the lives of millions just feels bad to me.

Edit: Also, no one is putting 2c-i on a tab of LSD. The doses are way different (~100ug vs 15mg) and chemists that make LSD tend to be pretty sold on it's potential to help humanity and try to keep the supply as pure as possible.

You may be thinking of "tusi" or pink cocaine, which is a drug mixture that tends to have ketamine and mdma mixed, and often has had fentanyl creep into the supply. Someone just decided to name it similar to Shulgin's 2C class of drugs for some reason, which is annoying and dangerous.
