Secondhand vapor (which is technically an aerosol) is the vapor exhaled into the atmosphere by an e-cig user. Like secondhand smoke, it lingers in the air long enough that anyone in the same room (assuming the room is small enough) is likely to inhale some of the exhaled aerosol. As the name indicates, the bystanders are not inhaling secondhand (or passive) smoke—because secondhand e-cigarette vapor simply isn’t smoke.
