People can always find a way around the rules.

A state-wide smoking ban in Arizona is no exception.

This may look like a willful disregard of the state's law, but what he's doing is far from illegal.

That’s a smokeless cigarette Ron McDonald’s smoking.

And the "smoke" that's coming out is actually an odorless water vapor.

It’s about the size of a pen with a water container and nicotine cartridge inside so smokers can get their fix without breaking the law.

McDonald holds exclusive rights to importing the cigarette, called Crown7, to the US.
