Just over 3% of American adults regularly use e-cigarettes, and 15% say they've tried it, according to 2016 data from the Centers for Disease Control and Prevention (CDC). This means that millions of Americans vaporize consistently or sporadically – and there is evidence that the number is increasing.
As they become more common, e-cigarettes – which are typically used as an alternative to traditional cigarettes or as smoking cessation aids – are increasingly being reviewed by physicians and regulatory agencies. In particular, the recreational use of adolescents has attracted the attention of legislators and health professionals, as trends such as "juicing" and "dripping" have spread to schools nationwide.
Meanwhile, research on the health effects of e-cigarettes will continue to accumulate. Some of the latest studies say about the habit, and what is still unknown.
The chemicals in E-Cigs are likely to come with health risks […] While e-cigarette aerosol "generally contains less harmful chemicals than smoke from burnt tobacco products," according to the CDC, it may still pose some risks. The formulas vary, but many e-cigarettes expose users to particles that can enter the lungs, possibly carcinogenic chemicals, heavy metals and other toxins, according to the CDC. A new study published in Scientific Reports also found that e-cigarette aerosol may contain more formaldehyde than previously thought. Formaldehyde may be carcinogenic at high exposure levels, according to the Environmental Protection Agency (EPA).
E-cigs come in a variety of flavors, from strawberries to creme brulee, and the chemicals they use are under review. A 201
E-cigarettes Can Help Teenagers to Smoking
E-cigarettes can not legally be sold to anyone under the age of 18, but that has not stopped teens from exploding over the years. A 2015 study found that teenagers who smoke e-cigarettes are likely to use other tobacco products than others, perhaps because of the habit of smoking nicotine.
Faced with this risk, the Food and Drug Administration (FDA) has made restricting the use of teenage e-cigarettes a priority and requested information from Juul and other e-cigarette manufacturers as part of this campaign. "There are no acceptable numbers of children using tobacco products," said FDA Commissioner Scott Gottlieb in an April statement. "These products should never be sold to children, sold or used by children – and we must do everything we can to protect children from nicotine."
It's not clear if e-cigarettes help you quit smoking  Many people turn to e-cigarettes as a bridge between traditional cigarettes and total smoking cessation because they typically give off nicotine and mimic the smoking ritual , But more research is needed to see if that is actually an effective strategy.
Several studies, including a study published in The BMJ in 2017, have found that e-cigarettes can increase the likelihood of a smoker being successful, but others have found the opposite. For example, a study published in the Annals of Internal Medicine in March found that those who used e-cigarettes consumed tobacco more than non-users at six months. Another study published in the New England Journal of Medicine in May 1945 found that money incentives encouraged smokers to quit as free e-cigarettes.
Different smoking cessation strategies may work for different people, but currently data on the effectiveness of vaping as a smoking ban tool is cloudy.
