What are the ingredients in electronic cigarettes?

Electronic cigarettes typically consist of a few main ingredients. The primary component is the e-liquid, which commonly contains propylene glycol (PG) and vegetable glycerin (VG). PG and VG act as the base for the liquid and help produce the vapor when heated. The e-liquid also contains various flavorings, ranging from traditional tobacco flavors to fruity and dessert options. Additionally, nicotine is present in some e-liquids, although it can be omitted entirely. Other than these core ingredients, electronic cigarettes may include optional components such as water, menthol, or cooling agents. It's important to note that e-cigarettes do not contain the numerous harmful chemicals and toxins present in traditional cigarettes, making them a potentially safer alternative for adult smokers looking to quit or reduce their tobacco consumption.
