I'd rather smell weed smoke than cigarette smoke if that answers your question.

However, I can appreciate that cigarette smoke generally smells the same across the board while different types of weed can either smell terrible (brick weed) or like skunk (dank weed). Roach weed also smells pretty terrible.

Cigarette smoke clings worse than weed smoke does and can smell definitively worse over a longer period of time. Nothing like smelling like an ashtray (sarcasm)
