Lawmakers are looking for ways to keep a newer smoking craze out of children's hands.

In order to smoke e-cigarettes, they have to be filled with liquid nicotine. And it’s the marketing of the bottles of liquid nicotine that lawmakers say needs to be regulated.  

The bottles have names like Naked Peach, Juice E Juice and Banana Split, which lawmakers say can attract children who might mistake the bottles for candy. And critics say that could lead to children being poisoned.

U.S. Senator Bill Nelson, D-Florida, announced Friday he has joined other lawmakers in filing new legislation designed to regulate those bottles, and make them child-proof to prevent kids from getting into them.

But long term, Senator Nelson says e-cigarettes in general need to be regulated.  But he says that will be a much tougher fight than the child-proofing.

“The FDA ought to regulate them.  We don’t know what’s in here. If this thing has been manufactured abroad, and a lot of this stuff is coming from China ... we don’t know what’s in it,” said Nelson.

Lawmakers hope by eventually regulating e-cigarettes in general, they will be able to ban advertising that’s now still allowed. 

In 1970, Congress passed the Public Health Cigarette Smoking Act, banning the advertising of cigarettes on television and radio.  That ban went into effect starting in January of 1971.
