Issue with resin

I never have any problems with smoking at all but SOMETIMES (not all the time just randomly) I will have this issue only ever with smoking resin, never once had this happen with rock, where I’ll be taking a hit and barely blow out any smoke. Ive burned it differently, I’ve used different pipes, I’ve used old and new chores and it still just randomly happens every once in a while but it drives me insane!!!

Need to know what makes this happen and if it’s something I’m doing does anyone have answers to this or solutions
