I found an E-cigarette in my 16 y/o's Room. Should I be worried about Vaping?

E-cigarettes were invented in 2003 in China by a Chinese Pharmacist named Li Chak, and have spread to every corner of the Globe. Sales in the United States have increased exponentially. Common age of the first e-cigarette in America is often adolescence; 15-16 years. The addition of various flavors and other additives make the e-cigarette highly attractive and marketable to youth. Unlike cigarettes, tobacco, and other tobacco related products, current FDA restrictions allow unfettered access to e-cigarettes.
