When it comes to e-cigarettes, Congress may have a hard time deciding what to buy

The Federal Communications Commission has launched a review of the legality of e-cigarette sales in the U.S. It’s the latest in a series of regulatory initiatives aimed at quashing the sales of the devices, which are unregulated by the federal government.

Last year, the agency ruled that vaping products sold on the Internet are tobacco products and cannot be sold in public.

But the FCC has been less stringent on e-cig sellers, with its new rules banning e-liquid sales from online retailers such as Amazon, and from certain vending machines.

The rules are still subject to change, though.

On Monday, the FCC also proposed new rules that would prevent e-liquids from being sold in the retail space.

While the FCC is reviewing the legality and the effect of e, e-juice sales, the issue is a hot topic among the public.

A new study by researchers at the University of California, Berkeley, and Columbia University found that e-cigs, which use batteries and nicotine, are more harmful than tobacco cigarettes, because of their high concentration of carcinogens, such as formaldehyde, polycyclic aromatic hydrocarbons, and formaldehyde-releasing agents.

The researchers said e-pipes are also more toxic than tobacco cigarette smoke.

E-cig users also reported higher rates of respiratory ailments, including asthma and bronchitis, than those who smoked traditional cigarettes, according to the study.

E-cigarettes have a “toxic cocktail,” and the inhalation of e will “have a profound impact on a person’s quality of life, health and quality of social interaction,” said the study, published in the journal Environmental Health Perspectives.

But some lawmakers have been vocal about the devices.

Rep. Joe Barton, R-Texas, said he supports efforts to crack down on the sale of e and vaping.

“I’ve been working with some of my colleagues on this issue for some time,” Barton told CNN.

“And I think it’s a good thing to do, and it’s something that should be addressed by the Federal Government, not a private industry.”
