As I walk around the sidewalks of campus, I pass people smoking cigarettes. Lately, however, something’s different. This time it’s not a normal cigarette, it’s an electronic cigarette (e-cig, also known as a vaporizer cigarette), and this catches me off guard.
E-cigs contain flavored water vapor that has two basic ingredients: vegetable glycerin and propylene glycol. They can also contain nicotine and distilled water. Some e-cigs can be purchased at places such as gas stations and only have nicotine in them, and some can be thrown away. Some also have a variety of flavors varying from candy and fruit to even tobacco, which people can buy at smoke shops.
