Second-hand smoke from a cigar is actually many times worse from the second-hand smoke of a cigarette because of the way it's designed and the gas particulates that are released from the burning end of a cigar. Carbon monoxide levels in second-hand smoke are much higher from a cigar than from a cigarette, and if you are someone who happens to frequent a cigar bar, often in a set off room in a restaurant where cigars are offered with every course in a meal and many tables of people are in there smoking cigars, what we have found with testing from the EPA is that the levels of carbon monoxide and toxins in that room where multiple people are smoking cigars exceed the human safety limits by the Environmental protection Agency.
