Tobacco (64) Q5. What are the pros and cons of electronic nicotine delivery systems (vaping)?

21 March, 2023

According to the CDC,

- Most e-cigarettes contain nicotine, which is addictive and toxic to developing fetuses. Nicotine exposure can also harm adolescent and young adult brain development, which continues into the early to mid-20s. E-cigarette aerosol can contain chemicals that are harmful to the lungs. And youth e-cigarette use is associated with the use of other tobacco products, including cigarettes.

- E-cigarettes are not currently approved by the FDA as a quit smoking aid. The U.S. Preventive Services Task Force, a group of health experts that makes recommendations about preventive health care, has concluded that evidence is insufficient to recommend e-cigarettes for smoking cessation in adults, including pregnant adults.

However, e-cigarettes may help non-pregnant adults who smoke if used as a complete substitute for all cigarettes and other smoked tobacco products.

- To date, the few studies on the issue are mixed. A Cochrane Review found evidence from two randomized controlled trials that e-cigarettes with nicotine can help adults who smoke stop smoking in the long term compared with placebo (non-nicotine) e-cigarettes. However, there are some limitations to the existing research, including the small number of trials, small sample sizes, and wide margins of error around the estimates.

- A recent CDC study found that many adults are using e-cigarettes in an attempt to quit smoking. However, most adult e-cigarette users do not stop smoking cigarettes and are instead continuing to use both products (known as “dual use”). Dual use is not an effective way to safeguard your health, whether you’re using e-cigarettes, smokeless tobacco, or other tobacco products in addition to regular cigarettes. Because smoking even a few cigarettes a day can be dangerous, quitting smoking completely is very important to protect your health.

Tobacco-free policies should be adopted and enforced in all public locations, especially in those that cater to or are frequented by children and youths, including all educational institutions, sports arenas, cultural facilities, shopping malls, fast-food restaurants, and transit systems.

All organizations involved with youths should adopt tobacco-free policies that apply to all persons attending or participating in all events sponsored by the organizations, and should actively promote a tobacco-free norm.

Parents should clearly and unequivocally express disapproval of tobacco use to their children, and, if smokers themselves, should quit smoking.
