Using e-cigarettes and/or vape pens has become increasingly popular in the past 7-10 years.
In the U.S. alone, there is an estimated 3,500 stores selling e-cigarette and vape pen devices. Many are moving towards vaping because they believe it to be healthier and safer than traditional cigarettes. Since there is no actual smoke being produced while using these devices, there is an associated illusion of fire safety.
