Now, when you say resin ( i hope im wrong ) are you talking about the stuff that is on the inside of your pipe and stem after you smoke a bowl? As in, lets scrape the resin out of your pipe and smoke it... Or are you talking about kief or hash? If its the former, i would advise against it, only cuz thats some icky stuff, and you already got most of the good stuff (and bad) when you smoked the bowl.
However, the latter... I see no reason why not... Kief and hash should work just as well in the alcohol as weed. I would be curious to see how a nice couple gram chunk of hash would dissolve?:stoned:
