Each day in the United States, about 4,000 kids smoke their first cigarette. “For teens, it may seem cool to smoke. But tobacco use at a young age can cause immediate and long-term health problems like cancer,” says Dr. Alexander Prokhorov, M.D. And, the tobacco industry may be to blame. The industry advertises products, like e-cigarettes, flavored cigarillos and hookahs, as “safe” and is capturing the attention of kids.
