Those little electronic puffers that allegedly confine the smoke and nicotine exposure to the willing lungs of smokers are no longer allowed in American airports nor aboard flights. The use, called vaping, must now be done in approved areas or outside.

The ban is also in effect in many other countries around the world. If you’re a traveling vaper who puffs the nicotine vapor, before you go, check out where you’re permitted to indulge in lung-filling vaping.
