The House Transportation Committee has approved a ban on electronic cigarettes on flights, even as a Congressman voiced his disapproval by vaping an e-cig during the session.

The measure, which was attached to a funding bill for the Federal Aviation Administration, would extend an existing ban on smoking traditional cigarettes in-flight to include e-cigarettes.

The amendment, filed by Del. Eleanor Holmes Norton (D-DC), was approved on a 33-26 vote.

During discussion, Representative Duncan Hunter (R-Calif) took a puff from a nicotine vaporizer. “This is called a vaporizer. There’s no combustion. There’s no carcinogens,” Hunter said after exhaling a white cloud. “Smoking has gone down as the use of vaporizers has gone up.”
