I've been hearing a lot about e-cigarettes. What are they and are they safe?

E-cigarettes are devices that deliver nicotine in aerosol form, usually through the use of a heating element. They come in many different shapes and sizes, with various levels of nicotine delivery. The main benefit is that they are much safer than traditional cigarettes, as they do not contain tobacco or combustion byproducts. However, some people have reported side effects such as throat irritation, coughing, dizziness, headaches, nausea, and difficulty breathing. It's important to consult your doctor before using an e-cigarette.
