only 1 experience. me and some friends had each done 2 cherry e pills per person in this dude's room, chilling with our dealer, the guy who's house we were at, and this girl. he had powder k on him. my friend wanted to leave since her roll was starting to kick in and she had to drive. for $5, he gave me a line, and i snorted it a few mins after my roll was kicking in. i dont think i felt the k on its own, but that was a crazy roll. id do it again if i could find it(my dealer's in jail now and will be for awhile).
