What? ...."potent" LSD?
...as opposed to?
Isn't LSD a substance who's properties are already set, by nature of its classification as LSD... and unless an entirely different substance is being discussed, potency is simply a matter of dilution... or lack thereof...
If anything, I would suspect any of a wide range of chemical substances that are far less well studied... I think LSD has never been more potent then when it was still legal and being tested on mental health patients (and a select few beatniks volunteering to assist with testing for pay... Including best selling author Ken Kesey, who wrote "One flew over the cookoo's nest" under the influence, and during his employment as night watchman in the same mental health facility that provided him the "medicine) ...so, it's a ludicrous stretch to make a connection between the aforementioned abomination, and a defined chemical compound with extensive research showing a far more peaceful behavioral response!
