U.S. health officials are sounding the alarm on e-cigarettes, with the surgeon general saying the product is a growing threat to the nation's youth.
"These effects can lead not only to (nicotine) addiction, but also deficits in attention and learning, reduced impulse control and mood disorders," he says.
E-cigs include a wide range of devices which all involve heating a nicotine fluid into an aerosol that users inhale. They are also known as e-hookahs, vape pens, vapes and tank systems.
Nicotine comes from tobacco, and Reynolds American is among the tobacco companies moving aggressively into the market as demand for traditional cigarettes continues its decades-long slide. Reynolds' brand is called Vuse.
Reynolds spokesman David Howard says he hasn't had time to read the full report but agrees with its message to youth.
The surgeon general acknowledges that there is still much confusion and uncertainty about e-cigarettes, and says more research is needed.
