Vaping and smoking cessation


Vaping is the act of inhaling and exhaling aerosol nicotine produced by e-cigarettes or other devices. Nicotine is a stimulant drug that speeds up the messages traveling between the brain and body. It is very addictive substance found in tobacco products. E-cigarettes come in many flavorings, such as mint, bubble gum, cotton candy, and with fruit flavors being the most popular among youth. They can increase the risk of cardiovascular disease when inhaled.

E-cigarettes are battery operated devices that individuals use to inhale an aerosol, which typically contains nicotine, flavoring and other chemicals, and are also known as electronic nicotine delivery systems (ENDS). E-cigarettes mainly contain four components: a liquid chemical, referred to as e-juice, cartridge, battery, the power source and atomizer, which is a heating element. The e-liquid or e-juice is the main component and contains nicotine, propylene glycol, glycerin, flavorings, heavy metals and other chemicals that are harmful. E-cigarettes are most commonly used amongst the youth population. As of 2019, around 5.3 million U.S. middle school and high school students use e-cigarettes.
