Vaping

With the recent increase in e-ciggs' popularity, evidence is beginning to emerge on what they do to people's health.

Here is a roundup of what scientists learned about marijuana during 2015.

A significant minority of teen e-cigarette users are vaping marijuana with the devices.

The percentage of U.S. college students who say they smoke marijuana daily or nearly every day is at its highest in more than three decades, according to a new survey.

Teens who "vape," or use electronic cigarettes may be more likely to start smoking regular cigarettes than teens who have never tried e-cigarettes, according to a new study.

A new study adds to the growing body of evidence that e-cigarettes might put adolescents at risk for taking up traditional cigarettes. Teen use of e-cigarettes is skyrocketing.

Depending on whom you ask, e-cigarettes are either a great tool to get people to quit smoking or another way to get people hooked on nicotine.

Smoking an electronic cigarette may come with unforeseen risks, such as exploding charging devices and accidental poisonings from nicotine exposure.

While vaporizing marijuana may be less irritating to the lungs, inhaling vapor from extracts or tinctures could create stronger withdrawal effects, researchers say.

Nicotine inhalers, which are devices similar to electronic cigarettes, have existed for years, but they were just not cool enough to catch on, researchers say.
