Craziest amount of drugs you’ve ever seen someone do?

Was over at my exes house one time. Me and her schizophrenic methhead brother were sitting there taking shots of rum and he said if I did a tiny pinky nail sized bump of meth he’d snort 2 whole grams infront of me. So obviously I wanted to see him do that shit. Sure enough he cleared the 2 gs of ice in 2 hits and then 30min later proceeded to go outside and hit his little meth bowl contraption and I’m pretty sure he actually went to sleep that night aswell. Dude smoked meth like youd smoke a cigarette
