This information answers frequently asked questions about electronic smoking devices, such as electronic cigarettes.
What are electronic smoking devices?
Electronic cigarettes (e-cigarettes), vaporizers, vape pens, Juuls, hookah pens, and e-pipes are all electronic smoking devices. Electronic smoking devices are battery-powered devices that can look and feel like regular cigarettes. Instead of burning tobacco like regular cigarettes, electronic smoking devices use pods filled with a liquid containing nicotine, flavorings, and other chemicals. The battery heats up the liquid, turning it into a vapor or mist that you breathe in. Using electronic smoking devices is also referred to as vaping, vaporing, juuling, or e-smoking.
Are electronic smoking devices safe to use?
The long-term health risks of using electronic smoking devices are still unknown. The US Food and Drug Administration (FDA) and other public health organizations agree that we need more research studies on the safety of electronic smoking devices.
While they don’t fill your lungs with harmful smoke like cigarettes do, electronic smoking devices still have nicotine and other chemicals in them. Vapors in e-cigarettes are made up of water as well as chemicals that can cause breathing problems in some people.
In 2016, the FDA started setting rules around the making, selling, and marketing of all tobacco products, including electronic smoking devices. People younger than 18 can’t buy any type of tobacco product. Health warnings have been placed on all tobacco products.
Is using a Juul safer than vaping?
Using a Juul isn’t safer than vaping. While Juuls come with liquid-filled pods in different flavors, these pods still contain nicotine. The nicotine in a Juul is more easily absorbed into your blood stream, making the vapor lighter and easier to breathe in. This makes you more likely to breathe in more nicotine for longer periods of time.
The amount of nicotine in 1 Juul pod is the same as in a pack of cigarettes. Juul pods also have more benzoic acid compared to other electronic smoking devices. Benzoic acid is known to cause coughs, sore throats, abdominal (belly) pain, nausea (feeling like you’re going to throw up), and vomiting (throwing up). Using a Juul isn’t safer than using any other electronic smoking device and can actually be more harmful.
Is using an e-cigarette with Vitamin E acetate safe?
While vitamin E is found in many foods and skin care products, research studies show that breathing in vitamin E acetate may cause breathing problems. Do not add any substances, including vitamin E acetate, to electronic smoking devices, even if you buy them from a reliable store.
Can electronic smoking devices help people quit smoking?
We don’t know whether electronic smoking devices can help or make it harder for people trying to quit smoking. They aren’t an FDA-approved method of quitting. We recommend that you use safe and proven methods, such as nicotine patches, gum, or lozenges.
Although research is still needed, some people are using electronic smoking devices to:
- Reduce the amount of harmful chemicals in regular cigarette smoke
- Help manage nicotine withdrawal cravings
- Cut down or quit smoking
- Keep from starting to smoke again (prevent smoking relapse)
While some people may smoke fewer regular cigarettes if they use electronic smoking devices, they may also be less likely to quit smoking altogether.
