While Florida lawmakers and local municipalities crack down on the use and sale and use of e-cigarettes, rules regarding when and where they can be used remain inconsistent.

Airports in the Sunshine State, which must follow the Florida Clean Indoor Air Act, prohibit traditional cigarettes. But since e-cigarettes are not tobacco products, most airports don't have any policy.

Orlando International is the exception, having passed a ban on the use of e-cigarettes.

But Florida's other airports, including Jacksonville International Airport, have no policy.

JIA spokesperson Michael Stewart told First Coast News that while airlines have prohibited their use on flights, the airport itself has no policy one way or the other.

Stewart acknowledged that "there will probably be more discussion regarding the use of them as their popularity grows."
