an example of how twisted the legal response to LSD celebrities could be (mind you the silly fcuker did escape from jail!)
LSD has always had a strange 'market' presence.
on one hand its idealised in the media and a huge source of inspiration for stereotypes, marketing and sanitized youth culture - in a way no other drug could be. maybe this is an association with 60s nostalgia, but even still.
then on the other hand is given the highest drug classification possible, even out-bidding heroin. acids deemed to have no value to society at all (heroin was for a long time a prescribed medicine for bronchitis...?!), so users and purveyors are subject to the same penalties as crack and meth defendants.
the penalty is seemingly regardless of the chemical - its based on the amount and intent of the chedules sheduling.
thing is: go out and get 100 methamphetamine users, 100 crack users, 100 crank users etc and compare them to 100 acid users.
i guarantee theres a difference.
whilst the authorities were busy playing spook n dressups to nab a bunch of oxford types, neo-nazis and coke dealers are out there involved in much more unsavoury businesses. for departments underfunded and the subject of public scrutiny, surely theres something wrong with that.
as for flashbacks, its worth looking into the molecular composition of LSD. its part of the indole-ring group that includes all sorts of endogenous chemicals within the human system (melatonin, seratonin, tryptophan etc).
its not impossible that previous use of acid or other indoles creates a pathway for future catabolism of endogenous chemicals to the same receptors acid triggers, with a similar effect.
indeed, the most powerful hallucinogen around - DMT - is endogenous. makes acid look like a water pistol, but is very short lived (10mins or so).
its released when a specific pathway for seratonin is not broken down, allowing the molecule to act on other receptors.
it does this most nights as part of the dreaming process.
whos not to say that acid use (or mushrooms or mescaline which both share the indole-ring family) doesnt mess with the serotonin-DMT catabolism process?
