1 doctor agrees
In brief: All of them
Carcinogens and nicotine are present in combusted tobacco, and non-smokers get plenty of it when in proximity to the source.
This is not enough to cause addiction, but it can precipitate asthma attacks, sinus troubles, and high exposure in the long term (e.g. Flight attendants, wait staff and bar tenders) can lead to tobacco related lung disease (cancer and chronic bronchitis for example).
