Many teens who start with e-cigarettes may be condemned to struggling with a lifelong addiction to nicotine and conventional cigarettes.-Former CDC Director Tom Frieden
Habitual E-cigarette Use Elevates CV Risk.
Habitual use was associated with a shift in cardiac autonomic balance toward sympathetic predominance and increased oxidative stress in a cross-sectional case-control study of habitual e-cigarette users and nonuser controls, aged 21-45 years. Both are associated with increased cardiovascular risk.
No END in Sight.
While the prevalence of tobacco smoking has been declining, the use of electronic nicotine delivery systems (ENDS)-e-cigarettes, vaporizers, hookahs-has been rising, especially among adolescents. Youths often perceive ENDS as safe, but nicotine exposure may have deleterious effects on the developing brain and ENDS may be a “starter” drug that may lead to further tobacco, drug, or alcohol use.
E-cigarette use did not predict elevated depressive symptoms in a study of college students in Texas, but depressive symptoms predicted e-cigarette use. Additional research was recommended to further establish the mechanisms for causality.
E-Cigarettes and “Dripping.”
About 1 in 4 high school adolescents who had ever used e-cigarettes also reported using them to inhale vapors produced by dripping e-liquids directly onto heated atomizers. Reasons for dripping: “produced thicker clouds of vapor” (63.5%), “made flavors taste better” (38.7%), “produced a stronger throat hit” (27.7%), and “curiosity” (21.6%). Study authors called for examination of the progression and toxicity of dripping and for educating youths about potential dangers.
Nicotine, but with Fewer Toxins.
Not all of the latest findings about e-cigarette use are gloomy. Former combustible cigarette smokers with long-term e-cigaretteâonly or nicotine replacement therapy (NRT)âonly use may obtain levels of nicotine roughly similar to those obtained by smokers of combustible cigarettes only. However, long-term NRT-only and e-cigaretteâonly use is associated with substantially reduced levels of measured carcinogens and toxins.
E-cigarette Answers for Patients.
French medical experts developed practice guidelines for managing e-cigarette smoking and providing information to answer patients’ questions: (1) E-cigarette risks are much lower than tobacco risks. (2) A dual user is at high risk for returning to exclusive tobacco use. (3) A smoker who wants to use e-cigarettes to quit smoking should be encouraged. (4) A vaper who is tired of vaping should be encouraged to quit. Specific guidelines are provided for various patient subgroups
E-cigarette smoking has been hailed as a safer alternative to combustible cigarette smoking, but e-cigarettes may have health risks of their own and the nature of the risks often is uncertain.Several clinical studies have added some clarity to the potential risks of smoking e-cigarettes.
