E Cigarettes... There is more to know

E-cigarettes and other vaping products are on track to out-sell cigarettes by the end of 2023. And more and more young people are trying e-cigarettes. So what do you need to know about them? Are they less harmful than using cigarettes or other burned tobacco products?

What Are E-Cigarettes?

First, they are not burned tobacco products. Most often, they contain nicotine solutions that are heated to make a vapor (hence the terms vape or vaping), and they’re usually powered by batteries. Some look like cigarettes and others can resemble flashlights. The first e-cigarettes were not produced by cigarette companies, but the cigarette companies have gotten into the business. E-cigarette and vaping products are available in specialty stores and convenience stores around the US with varying restrictions on purchase by youth under 18.

E-cigarettes don’t necessarily contain nicotine. Some popular products contain little or no nicotine and levels can vary from brand to brand. And nicotine isn’t always the reason someone might try e-cigarettes. In Canada – where nicotine-containing e-cigarettes are not approved, but still widely available – only 38% of adult cigarette smokers who also use e-cigarettes “always use nicotine” and 30% “sometime use nicotine” when vaping. And only 4% of those who never smoked tobacco reported using nicotine when vaping.

Why Do Young People Use E-Cigarettes?

A 2014 national high school survey finds more monthly vapers than monthly smokers: 17% of US 12th-grade students report using e-cigarettes in the past 30 days compared to 14% for tobacco cigarettes. We also know that patterns of infrequent, non-daily use of various tobacco and nicotine products may be increasing among young people. But trying e-cigarettes does not automatically lead to daily use.

Young people might also be influenced to try e-cigarettes because of how they are priced and promoted. They can be cheaper than traditional cigarettes and may be perceived as safer. Other features, like flavors can also support use in all age groups.

As e-cigarettes become more popular and more visible, young people will start trying and using these products. And because products keep changing, they will often try different kinds of e-cigarettes.

Youth is a time when individuals experiment with and get into trouble with psychoactive substances, including nicotine-containing e-cigarettes. In 2014, 44.4% of 12th-graders had ever used marijuana/hashish, and 35.1% had used in the past year; 41.4% reported being drunk in the past year. Users of one type of psychoactive substance are more likely to use others, like caffeine, alcohol, nicotine, THC or prescription drugs.

Is Vaping Safer Than Smoking?

The best evidence to date shows that using e-cigarettes is very dramatically less dangerous than cigarette smoking. Death from all causes within the ages of 25 to 79 is three times higher for smokers than never smokers. Compared to smoking, long-term health effects of e-cigarettes have been judged as likely “much less, if at all, harmful to users or bystanders.”

The 2014 Surgeon-General Report concluded that “The burden of death and disease from tobacco use in the United States is overwhelmingly caused by cigarettes and other burned tobacco products; rapid elimination of their use will dramatically reduce this burden.”

Recent reports suggest that vapers should be cautioned about how they use high-voltage devices because they can produce high levels of the carcinogen formaldehyde. But that, however, is not one of the common ways people use e-cigarettes. High voltage devices and long puffs can produce a bad taste that is avoided.

Burned cigarettes contain many carcinogens: the FDA lists 79 “harmful or potentially harmful” carcinogens in tobacco products and tobacco smoke.

Keep in mind that reports of a product being “not safe” in some way does not necessarily mean that it cannot overall be much safer than another product.
