LA CROSSE, Wis. (WKBT) -

E-Cigarettes are commonly marketed as alternatives to smoking and even a way to quit.

However the World Health Organization now says they are still dangerous. They're especially concerned about nicotine contents and other chemicals that can cause cancer. It wants to see global regulation on the devices to prevent the devices from getting in the hands of kids and stopping potential health risks are further research is conducted.

"Electronic cigarettes contain nicotine and other chemicals and usually a few cancer causing substances although a much lower level than a conventional cigarette, it doesn't mean that there not without risk,” said Dr. Armando Peruga, of the W.H.O.’s Tobacco Free Initiative.

E-Cigarette companies say only water vapor is released into the air but a local health educator says more research needs to be done.

"We need to slow down and think about this technology, this emerging product to know is it safe? Is it a reliable method for quitting? What else is in the water vapor?” said La Crosse County Health Educator Paula Silha.

Silha said she's most concerned about promotions that seem to be targeting young people.
