Sure. OTOH, if they're smoking and the hotel is ventilated in such a away that I can smell it, that is certainly inconveniencing me, and the threshold between smelling it and setting off my wife's asthma if she's along is not
that high.
If I can smell it in my room or the hallway, and I'm in a non-smoking room in the US, I'm complaining, and escalating as far as necessary. Outside the US, norms are different, although I try to stick to hotels that have a non-smoking floor or wing and not just non-smoking rooms.
