I dont know why it tastes bad, but I know what you're talking about. I don't know what type of vape you're using, or if it would even make a difference, but I like to use mint leaves in my volcano to combat shitty tasting weed. A little goes a long way and it does a nice job of masking the taste.

we aren't revolutionaries, but we are the revolution! sometimes I think that the whole movement is just me and you, or that maybe we'd all be better off if that were true, because then at least we'd know where we stand. and we could tell our comrades apart from "the man"
