I haven't twitched for months, even when really high, but last night i scraped my whole pipe and put some small buds under the bowl to get really resinated and smoke the last of those last night, well i had 3 huge hits off this (i usually have about 8-10 hits, to get me fucked) and i was soooo high, twitching uncontrollably, i couldn't walk for long (and didn't want to) as my legs were so numb and twitching lol, it lasted about an hour of constant numbness and twitching
