Abstract

Electronic cigarettes (ECs) are battery-powered nicotine delivery devices that have rapidly gained popularity and attention globally. ECs work by heating a liquid to produce an aerosol that usually contains nicotine, flavoring compounds, and other chemicals, which are inhaled during vaping. EC aerosols are depicted to contain a lower number and overall quantity of harmful toxicants than conventional cigarettes (CCs). However, emerging research indicates that EC aerosols contain harmful ingredients including ultrafine particles, volatile organic compounds, and heavy metals. One common ingredient found in both CCs and ECs is nicotine, which has been shown to be both highly addictive and toxic. Particularly relevant to our current review, there is an enormous amount of literature that shows that smoking-derived nicotine exacerbates ischemic brain damage. Therefore, the question arises: will EC use impact the outcome of stroke? ECs are highly popular and relatively new in the market; thus, our understanding about the long-term effects of EC use on brain are lacking. The current review strives to extrapolate the existing understanding of the nicotine-induced effects of conventional smoking on the brain to the possible effects that ECs may have on the brain, which may ultimately have a potential for adverse stroke risk or severity.
