Lung cell impairment can occur with exposure to e-cigarettes, but other short and long-term effects of vaping remain unknown.
The use of electronic cigarettes, or e-cigarettes, is becoming increasingly popular in the United States, especially amongst teenagers. An e-cigarette is a device that produces an aerosol by heating a liquid, allowing users to inhale the aerosol into their lungs. This is also sometimes referred to as vaping or juuling, named for a popular brand of vaping device. E-cigarettes can appear like traditional cigarettes or cigars, while others look like ballpoint pens or USB devices.
