Many teens who use e-cigarettes say they enjoy performing tricks with the vapor, such as blowing smoke rings or creating funnels of smoke that look like tornadoes. Performing tricks is one of the top two reasons teens say they enjoy using e-cigarettes, Reuters reports.
The other top reason is the flavoring in nicotine liquid. The wide range of flavors include cappuccino, pomegranate and single-malt scotch.
The findings about vapor tricks come from a study by researchers at Yale School of Medicine. The Yale team asked 5,400 Connecticut teens to explain what they found “cool about e-cigarettes.”
