E-cigarettes inside airports: Should they be banned?

Electronic cigarettes or e-cigarettes are not allowed on flights, but a number of u.s. airports are divided on whether they can be used inside the terminals.

USA Today reached out to some of the busiest airports and found that; Ronald Reagan Washington National Airport, Las Vegas McCarran International Airport, Minneapolis-St. Paul International Airport and Charlotte Douglas International Airport are among airports that permit the use of e-cigarettes inside.

Miami International Airport says e-cigarettes are OK for now, but says it is reviewing its policy.

However, New York City's Laguardia International and John F. Kennedy International Airports both ban and permit e-cigarette use - depending on the terminal you're in.
