Generally I would say that burning(flame/smoldering) anything is bad for you. Even simplest hydrocarbons (methane, propane, butane) with imperfect combustion have negative effects. You can make it slightly better, but smoke is most likely always carcinogenic.

replyIndeed they are, and you should also minimize exposure to the fumes from cars/trucks/powerplants and try to improve indoor ventilation.
replyI don't generally suck on the tailpipe of my car like a cigarette or vape.
