phenazepam is a benzodiazepine developed in the Soviet Union in 1970s, which is always a good start. it's a benzodiazepine, with low-sub-milligram therapeutic doses, strong anretrograde amnesia, and a staggering SEVENTY TWO HOURS half-life
seriously read these stories https://www.reddit.com/r/Drugs/comments/1mlemu/the_drug_that_ruined_my_life_in_two_weeks/ccaglu3/

one of those stories involves people completely blacking out in a delirium for THREE MONTHS. another didn't get back their short-term memory after two weeks of use and five months of recovery

@whitequark HOLY FUCKING SHIT this is TERRIFYING

@er1n I know right

@whitequark currently imagining some dipshit who thinks it would be a fun experience to take a '''small amount''' of phenazepam
god, these are utterly terrifying drugs
like, a SEVENTY TWO HOUR HALF LIFE. are you fucking kidding me.

@er1n @whitequark some folks will do anything if they get bored enough, I suppose.

@munin @er1n I don't judge them, at least if they manage to not fuck up the lives of people around them needlessly

@whitequark @munin that's true. but also. consider. THREE MONTHS.
*mind blown*

@er1n @whitequark Fairly literally in that case ;-)
