  • Here is the rule of thumb: one cigarette per day is the rough equivalent of a PM 2.5 level of 22 μg/m 3. Double that level, and it is equivalent to 2 cigarettes per day. Of course, unlike cigarette smoking, the pollution reaches every age group. The EPA estimates 5 that the average air pollution in the United States in 2013 was 9.0 μg/m 3.
