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.
