Vaping and E-Cigarettes: A Practical Checklist

Battery-powered devices that heat a liquid, usually containing nicotine, into an aerosol that is inhaled. E-cigarettes are the most commonly used tobacco product among US middle and high school students, and nicotine harms the developing brain.

Key takeaways

• Nicotine: most e-cigarettes contain nicotine, which is highly addictive
• Brain development: continues until about age 25, and nicotine can harm it
• Most useful single change: Talk openly with teens about vaping and listen to their reasons.
• Commonest mistake: Buying vaping products from informal or online sellers, or THC vapes from unlicensed sources.
• See a doctor if any of the signs under "When to speak to a doctor" below apply to you.

Do

• Talk openly with teens about vaping and listen to their reasons
• Use free help to quit, such as 1-800-QUIT-NOW or smokefree.gov
• Ask your doctor about FDA-approved quit-smoking medicines if you are an adult who smokes
• Store e-liquids locked away from children; swallowing them can be poisonous

Do not

• Buying vaping products from informal or online sellers, or THC vapes from unlicensed sources
• Using e-cigarettes and cigarettes together
• Assuming vaping is harmless for young people

When to speak to a doctor

See your doctor for a cough, chest pain or shortness of breath that does not go away. Call Poison Control at 1-800-222-1222 if a child swallows e-liquid, and 911 if they have a seizure, trouble breathing or are hard to wake.

How this page was put together

Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarized or generalized beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
