Neither smoking nor vaping are beneficial to human health. Based on available evidence, smoking seems more harmful than vaping, but this doesn't mean that vaping is safe. Vaping is largely perceived as a safer alternative to smoking. While vaping does not expose users to tar or carbon monoxide, two of the most dangerous elements in tobacco smoke, vaping is far from safe and has its own health risks.
Vaping involves inhaling an aerosol containing several chemicals, such as nicotine and flavorings, through an e-cigarette or vaporizer.
