With MDMA if you have 150 mg of powder, you have 150mg of powder, i.e. this is the upper bound on how much substance you will take (be it MDMA or not), i.e. there can't be MORE than 150 mg.
With LSD it's always a solution (either in paper or in liquid), so you can only trust the producer.
Sure it can’t be more than 150mg of MDMA, but that doesn’t tell you how much meth / fentanyl / whatever is in there, so it’s not like you’re somehow in a safer boat with it. At least it’s easier to test LSD for adulteration due to it being such a different chemical than what it could be adulterated with.
That's why I don't vape nicotine. Small molecule, sold in concentrate, mixed by who knows who. A high school chemistry experiment. If a butcher offers you a 4-ton pork chop by mistake at least it's obvious you shouldn't stand underneath it. Cigs are cigs but nicotine in solution is an assassination weapon. Ask the CIA.
People who long for the old days must realize there were serious mental issues in society. It wasn't a simple case of the dids and the didn'ts. People were batsh*it insane, and I don't mean hallucinogens, especially not LSD that is not directly toxic at all. People were literally driven to hysteria by the ~thought~ of LSD.
The juggernaut opposing LSD and set the stage for the endless war on drugs. It was the boogeyman that could justify any legal atrocity. Lives could be destroyed, tripping teenagers were treated as if it was a life threatening medical emergency, which is trauma and sadism. The monkey brain slides that implied chromosome damage was deliberately not replicated after the mistake in handling was found, and the study was cited for a decade after author retracted it. Just too convenient to repeat the lie.
It is not surprising that G. Gordon Liddy a toady in Nixon's cabinet, spoke up at a meeting briefly to suggest putting LSD on opposition journalist Jack Anderson's steering wheel. As if it's presence would cause an instant accident that flipped the car 5 stories into the air. He was showing off his ignorance and trying to boost his reputation as a 'fixer'.
But far more dangerous than LSD, a few impaired people here and there was the mass hysteria to the 'plot' and 'scandal' that wouldn't work anyway and 3/4 of the country was consumed by it. That was in 1972.
Then along comes fentanyl that is really scary and not much serious pushback, until 'recently'.
