Vaping, even if it is nicotine-free, can be harmful. Although it is a common substitute for smoking, it involves vaporizing a liquid that may cause irritation to the lungs and throat when inhaled. Furthermore, many of the substances used in e-cigarettes have not been thoroughly tested for safety, so the long-term effects of vaping are still largely unknown. Some studies have even suggested that the chemicals used in e-cigarettes may cause damage to DNA and increase the risk of cancer.
It is important to note that vaping can be addictive and may lead to the use of other tobacco products.
