While short term use may seem harmless, especially as electronic forms of consuming nicotine are often marketed as “safe-alternatives”, long-term use can result in a variety of health problems and those with nicotine dependence can be at risk of abusing other substances.

* Electronic cigarettes, also known as e-cigarettes or e-vaporizers, are battery-operated devices that deliver nicotine with flavorings and other chemicals to the lungs in vapor instead of smoke. E-cigarette companies often advertise them as safer than traditional cigarettes because they don’t burn tobacco. But researchers actually know little about the health risks of using these devices. “Cigarettes and other tobacco products”
