My understanding is that, today in the US (and other markets so far as I know), it is far easier to know a pharmacist than a genuine LSD chemist, though I am several years out of that particular market.
Would be nice to know there's been a resurgence of access to ergot via improvement in Claviceps growth or some nifty novel synthesis we didn't have a few years ago.
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.
I am calling out a pattern. It's a bit similar to pharma going into the jungle, taking some natural compound (possibly known to an indigenous tribe), modifying the chemistry just enough to patent it and call it a miracle. The dealer gets life in prison, the Sackler family literally killed thousands, but merely had to pay a fine and do some rebranding.
If LSD wasn't arbitrarily outlawed, your concerns wouldn't exist. ID and purity considerations are purely consequences of being made illegal. It was always synthesized by highly educated and responsible chemists, because the chemistry demands it. It was never an honest public health concern, it's not addictive, practically lacking any toxicity.
MDMA also got this treatment. Immersion with the collectivist teachings of Christ was decided a sinful desire, but now treating the PR problem of broken cogs in the war machine may be ruled acceptable in the eyes of God.
