E-cigarettes produce vapor rather than smoke, which means that they do not produce the harmful tar and carcinogens found in cigarette smoke. This may make them less harmful to users and those around them.

Vaping can be less expensive than smoking over time. While the initial cost of purchasing a vaporizer or e-cigarette may be higher than a pack of cigarettes, the long-term cost is often lower because e-liquid (the substance used in e-cigarettes) is cheaper than cigarettes.

E-cigarettes do not produce the unpleasant smells associated with smoking. This can be particularly beneficial for people who are concerned about the impact of their smoking on others.
