Six people in America have died from lung illnesses tied to vaping e-cigarettes, and health officials continue to investigate the root cause of the illnesses.

Medical ethicist Arthur Caplan told Boston Public Radio Thursday it makes sense to pull vaping products off the market for the time being.

“The fact is, pulling this one off the market makes sense. I’m not going to bemoan it, even though there’s more to be done.”

While President Donald Trump's administration is leading the charge to ban e-cigarettes, his critics argue he could prevent more deaths by taking action on firearms.

Caplan noted an e-cigarette ban is a politically easier move than banning tobacco products altogether.

“To tell you the truth it’s pretty clear the FDA was getting ready to go after vaping … They were in their wind up if you will, to go after these guys, then they had these outbreak of deaths, they don’t have the lobbying influence and the huge number of addicts (as the tobacco industry,)" he said. "So its hard, difficult, next to impossible, to really go after tobacco, but this thing is new so I think politically they just saw an opening. It’s pragmatic.”

Art Caplan is the Drs. William F and Virginia Connolly Mitty Chair, and director of the Division of Medical Ethics at NYU Langone Medical Center. He’s also the co-host of the everyday ethics podcast.
