So this is givin' me flashbacks to like 2002 and a massive internet argument....
Bottom line? You smoke that shit, you will get high. Chances are that high will come with a headache, and typically the headache comes after you cough your lungs out because resin smoke is harsh as a mother fucker.
You'll get high, it'll quench whatever thirst you feel... but there WILL be immediate side effects. Some people love those side effects (and I feel they're dealing with something akin to Stockholm Syndrome) and some people realize that they're just not worth it.
Either way, you're safe doing this. People have done it for generations at the least. Whether you enjoy the experience, however.... well, let us know how it goes.
Personally, I consider resin and residue as trash. Less than that, really... I mean, it's not even to be considered. And I'm not trying to be snobby when I say that, I just look at a lump of scraped resin from a pipe and then have flashbacks to 3rd grade DARE pictures of a lung just completely fucked with tar... and I look at the resin and see that tar, and think to myself "nah dawg, I'm good."
Like, that's literally my whole bias against resin. Fuckin' DARE classes from the 90s.
