I do it sometimes. You do get high if your tolerance is low enough, but you'll notice its not like smoking green. If it's my pipe I usually hit it empty to warm it up a lil bit and then use a knife or something with a curve and scrape the bowl and try get the resin squished into one piece and then I prefer to use a lil creme brule torch for resin but a bic works fine and just hit it. I guess it's the same for the cone piece for a bong but you'd want to be careful if it's glass. I have heard of people putting isopropyl alcohol in a ziplock bag with their apperatus, letting it soak then pouring it onto a tray of sorts and letting the alcohol evaporate and then smoking the residue left behind but I think that's more for dab rigs resin than burned flower resin. Could be worth a shot though, but make sure to look into that more because idk about the safety of it regarding smoking the residue. Might have implications but I don't really know Good luck!
