While electric cigarettes are not the same as smoking real cigarettes, there are things users should be aware of.

What is nicotine?

Nicotine is the primary ingredient in tobacco products.

Nicotine in products is used to aid in smoking cessation. Using a controlled amount helps reduce withdrawal symptoms when you quit smoking and is intended to help curb urges to smoke. It works by providing low levels, which may help you to quit smoking by lessening physical signs of withdrawal symptoms. Remember, you are still taking in nicotine so you are not really getting rid of it but just substituting the delivery method. For some, changing the delivery method is worth it since you don't have the smell, tar, and other chemicals in cigarettes.
