The most common side effects associated with electronic cigarettes include nausea, vomiting, throat irritation, coughing, and shortness of breath. Additionally, there is some evidence that they may increase the risk of heart disease and lung cancer due to their high levels of nicotine. In addition, many users have reported experiencing a variety of other symptoms such as dizziness, headaches, and difficulty concentrating.
