MONDAY, Dec. 15, 2014 (HealthDay News) -- Nearly a third of Hawaiian high school students have tried e-cigarettes, new research suggests.

This finding reflects a growing trend of American teens flocking to the nicotine inhalation devices, according to public health experts.

The overall rate of e-cigarette use in the new study is higher than found in mainland U.S. studies over the past several years. But e-cigarette use is "accelerating very rapidly" across the nation, according to Dr. Norman Edelman, senior consultant for scientific affairs at the American Lung Association.

An e-cigarette is a device that turns nicotine, flavorings and other chemicals into an inhalable vapor. Many e-cigarettes are designed to resemble tobacco cigarettes, according to the U.S. Food and Drug Administration.

The FDA is still reviewing evidence about the safety of e-cigarettes, but the agency has proposed banning sales of the devices to minors. According to the FDA's website, the devices still haven't been fully studied and it's impossible to know their potential risks or even how much nicotine is being inhaled during use.

The new study surveyed more than 1,900 teens in Hawaii. The average age was between 14 and 15 years old. The teens were in ninth and 10th grades, and from both public and private schools, according to the study. The survey assessed e-cigarette and cigarette use, alcohol and marijuana use, and psychosocial risk factors for substance use.

The researchers also found that 12 percent reported using both e-cigarettes and tobacco cigarettes, while 17 percent had used e-cigarettes only and 3 percent used cigarettes only.

Study author Thomas Wills, interim director of the Cancer Prevention and Control Program at University of Hawaii Cancer Center, said his team was surprised by the research results in several ways.

"We had thought that persons who used e-cigarettes would look pretty much like smokers on the psychosocial variables we measured, like sensation seeking, impulsivity and peer smoking," he said. "It turned out that the students who only used e-cigarettes had a lower risk profile than smokers and dual users -- persons who use both cigarettes and e-cigarettes."
