Vaping can cause more damage to DNA compared to smoking regular cigarettes, according to a new study which also found that both vapers and smokers had more than twice the DNA damage of nonusers.
The study, published in the journal Nicotine & Tobacco Research on Feb. 14, collected samples of epithelial cells from test participants’ mouths, testing them for genetic damage. The researchers found that vapers had 2.6 times more DNA damage compared to nonusers while smokers had 2.2 times the DNA damage compared to nonusers. This indicates that vaping can be more damaging to the DNA than smoking cigarettes.
DNA damage to the oral epithelial cells lining the mouth is a change that is associated with a higher risk for several chronic diseases, including cancer….
