Are levels really the same as for indoor smoking?
Yes, under some conditions. When measured close to a person who is actively smoking, air pollution can reach very high levels that are similar to levels observed for indoor smoking. However, the difference for outdoor air is that pollution levels disappear rapidly when a smoker stops smoking, whereas indoors they can persist for several hours.
