Aren't campfires and barbeques also polluting?

Some have argued that exposure to toxic chemicals can result from being near campfires or barbeques (outdoor grilling) -- in addition to from cigarettes -- but that no one is talking about banning these sources. This argument is a red herring and irrelevant to the consideration of smoking bans. Other sources should be considered independently from tobacco. In fact, we are unaware of the ability of people to indiscriminately burn campfires or have BBQs at cafes and on city sidewalks. But they can currently generate similar kinds of air pollution in many locations by smoking a cigarette or cigar. If people do not want to be exposed to the substantial air pollution caused by outdoor smoking in places they visit, then they are justified in pushing for smoking bans.
