Electronic cigarettes: what are they and what do they do? #MMPMID26774031
Ann N Y Acad Sci 2017[Apr]; 1394 (1): 5-30 PMID26774031show ga
Electronic cigarettes (ECIGs) use electricity to power a heating element that aerosolizes a liquid that often contains solvents, flavorants, and the dependence-producing drug nicotine for user inhalation. ECIGs have evolved rapidly in the past 8 years, and the changes in product design and liquid constituents affect the resulting toxicant yield in the aerosol and delivery to the user. This rapid evolution has been accompanied by dramatic increases in ECIG use prevalence in many countries, including among adults and especially adolescents in the United States. This increased prevalence of a novel product that has the potential to deliver nicotine and other toxicants to users? lungs drives a rapidly growing research effort. This review highlights the most recent information regarding the design of ECIGs and liquid and aerosol constituents, the epidemiology of ECIG use among adolescents and adults (including correlates of ECIG use), and preclinical and clinical research regarding ECIG effects. The current literature suggests a strong rationale for an empirical regulatory approach toward ECIGs that balances any potential ECIG-mediated decreases in health risks for smokers who use them as substitutes for tobacco cigarettes and against any increased risks for nonsmokers who may be attracted to them.
