A note before we begin: When we use the word "tobacco" on this page, we are referring to commercial tobacco products manufactured and sold by the tobacco industry that are designed to create addiction. This is different from traditional tobacco, which holds deep cultural, ceremonial, and spiritual significance for many Native and Indigenous communities and is used in a sacred, intentional way. These are not the same thing. To learn more about traditional practices and Native and Indigenous well-being, visit our Native & Indigenous Youth page.

What is Tobacco?

Tobacco is a plant that contains nicotine, a highly addictive chemical that stimulates the brain and causes dependency. Just as cannabis is a drug class, tobacco is a drug class. Commercial tobacco products come in many forms, but they all have one thing in common: they contain and deliver harmful chemicals, with nicotine as the focal point.

Nicotine is a toxic substance — the addictive chemical found in all commercial tobacco products. Historically, nicotine was sourced from the tobacco plant. Today, it's also produced synthetically in a lab. Regardless of its source, nicotine is harmful to the body and brain.

Commercial tobacco use is the single most preventable cause of disease, disability, and death in the United States. No commercial tobacco product is safe to use. And "safer" never means "safe."

Two sources of nicotine

Plant-based nicotine Nicotine sourced from the tobacco plant. As the tobacco plant grows, it absorbs chemicals from soil and fertilizer, including cadmium, lead, and nitrates. During manufacturing, additional chemicals may be added to help nicotine absorb into the body more quickly. Plant-based nicotine is found in cigarettes, cigars, pipes, and many e-cigarettes and oral nicotine products (such as Velo, on!, Zyn™, and Lucy™).

Synthetic (lab-made) nicotine Synthetic nicotine is made in a laboratory. Tobacco companies often label products containing synthetic nicotine as "tobacco-free" or "tobacco-leaf free" — but this is misleading. These products still contain nicotine and are still classified as tobacco products. Synthetic nicotine is used in some e-cigarettes (such as PUFF Bar™) and oral products (such as Rush®).

Important: "Tobacco-free" does not mean nicotine-free — and it doesn't mean safe.

Some brands also add nicotine salt (nic-salt) to products to reduce the harsh feeling of nicotine on the throat, which allows the body to absorb even higher levels of nicotine more quickly.

Types of commercialized tobacco products

Tobacco products come in many forms. All of them deliver nicotine and other harmful chemicals to the body.

  • E-cigarettes / vapes — electronic devices that heat a liquid into aerosol. Nicotine delivery can be very high.
  • Nicotine pouches — small pouches placed between the lip and gum (e.g., Zyn, on!, Velo). Contain 1.5–16 mg of nicotine per pouch — the equivalent of up to 4–5 cigarettes in a single pouch. (Source: Stanford REACH Lab)
  • Cigarettes — smoked tobacco; menthol varieties make nicotine more easily absorbed.
  • Cigars and cigarillos — available in many flavors; not regulated the same way as cigarettes.
  • Hookah tobacco — often used socially; a single session can deliver significantly more smoke than a cigarette.
  • Smokeless tobacco — snus, dip, and chewing tobacco placed in the mouth.
  • Oral tobacco products — includes gum, lozenges, toothpicks, and tablets. These can be mistaken for FDA-approved nicotine replacement therapy (NRT) but are sold as commercial tobacco products where tobacco products are sold.
  • Pipe tobacco

If it's sold where tobacco products are sold, it IS a tobacco product.

Nicotine: It's a numbers game

The FDA does not regulate how much nicotine can be added to tobacco products. This means nicotine levels vary widely and can be deceptively high.

One disposable e-cigarette can deliver the nicotine equivalent of an entire pack of cigarettes, yet many users go through one in a day or two, not three weeks.
Add some sort of graphic here - either a chart OR a picture of cigarettes and a vape side by side

Here's how the math works:

Some brands of disposable e-cigarette have 6% nicotine (= 60 mg/mL) and 6.5 mL of e-liquid. That's 390 mg of nicotine total — equal to 19.5 packs of cigarettes — in a single device.

Oral products vary widely, too:

  • Nicotine pouch: 1.5–16 mg per pouch (up to 4–5 cigarettes per pouch)
  • Nicotine gum: 2–6 mg per piece
  • Nicotine lozenge: 2–4 mg per lozenge
  • Nicotine toothpick: 2–3 mg per toothpick

There is no safe level of nicotine in any tobacco product.

The danger of flavors

Flavors are one of the biggest reasons young people try tobacco products. Four out of five young adults who have ever used tobacco reported that their first product was flavored. (cite Truth Initiative here?)

Flavors aren't just appealing. They're harmful. When flavoring chemicals are heated, they transform into new compounds linked to tissue inflammation and suppressed immune function. Cinnamon, mint, and menthol are among the most chemically dangerous. Tobacco companies also use terms like "ice," "frost," "chill," and "freeze" to disguise menthol, a flavor that makes tobacco products more addictive.

"Banana ice" isn't just appealing. It's addicting.

Is one tobacco product safer than another?

This is a question many teens ask. Here's the honest answer:

When someone asks, "Is vaping safer than cigarettes?" a better question is: "Is this a safe product to use?" The answer is always no.

Tobacco companies sometimes compare their products to cigarettes, one of the most researched causes of disease and death in history. That's not a high bar. No matter what tobacco product is being discussed, none of them are safe. Whether it's a nicotine pouch, an e-cigarette, or a cigarette, each delivers a toxic substance to your body.

Nicotine toxicity/poisoning is a medical emergency, and is a serious risk of using high-nicotine products. Signs include:

  • Nausea and vomiting
  • Dizziness and headache
  • Stomach pain and confusion
  • Abnormal heart rhythms
  • Shaking, facial twitching, staring blankly, or fainting (signs of seizure-like activity, per the FDA)

If you or someone you know experiences these symptoms, stop using immediately and contact a doctor or trusted adult.

Why It Matters

Tobacco and nicotine products are designed to create addiction, and they're effective at it. The adolescent brain is especially vulnerable. Nicotine changes how the brain develops and wires itself, increasing the risk of lifelong dependency. These aren't just short-term concerns. The damage tobacco causes shows up both today and years from now.

  • Brain Impact

    Your brain doesn't fully develop until around age 25. This means teens and young adults are at significantly higher risk of becoming addicted to nicotine than adults. Nicotine acts on the brain's reward system — creating intense cravings that make it very hard to stop.

    Nicotine can disrupt normal brain development, making it harder to:

    • Remember information

    • Focus and pay attention

    • Learn new things

    • Manage emotions and impulse control

    Nicotine can also worsen mental health conditions, including anxiety and depression.

    How nicotine travels to the brain matters:

    • When smoked or vaped, chemicals are inhaled into the lungs, where the heart pumps them rapidly to the brain and the rest of the body.

    • With oral products like nicotine pouches, chemicals are absorbed through the gums and the lining of the mouth, traveling to the brain through the mucosal membrane. This creates a slower, steadier delivery, but one that is just as harmful and easier to use discreetly.

  • Physical Health Impact

    Nicotine and tobacco chemicals affect nearly every organ system in the body — both immediately and over time.

    Cardiovascular effects:

    • Raises heart rate and blood pressure

    • Narrows blood vessels, reducing blood flow to the brain and organs

    • Causes blood to clot faster, increasing the risk of heart attack, heart disease, stroke, and circulation problems

    Gastrointestinal effects:

    • Nausea, vomiting, diarrhea, and indigestion

    Neurological effects:

    • Dizziness, headache, anxiety, nervousness

    Sleep effects:

    • Insomnia and disrupted sleep patterns

    Other physical harms:

    • Increases risk of many types of cancer

    • Raises blood glucose, increasing risk for diabetes Damages gums and causes tooth decay

    • Secondhand smoke and secondhand aerosol are also dangerous to those around you, including pets

    Note for teens and dual users: Many teens also consume high amounts of caffeine. Nicotine and caffeine used together compound stress on the cardiovascular system, increasing risk of heart-related effects.

    Lung Impact

    Tobacco products, whether smoked, vaped, or used in other inhaled forms, cause serious damage to the lungs.

    • Damages cilia, the hair-like structures in the airways that sweep out germs, dust, and particles

    • Irritates and inflames the airways

    • Triggers asthma flare-ups

    • Lowers the amount of oxygen in your bloodstream, causing shortness of breath

    • Weakens the lungs' ability to fight off infections

    • Can cause chronic obstructive pulmonary disease (COPD) and emphysema

  • Mental Health Impact

    Nicotine addiction and the disruption it causes to brain chemistry can have lasting effects on emotional well-being.

    • Nicotine use is strongly linked to increased anxiety and depression

    • Withdrawal from nicotine, even brief periods without it, causes irritability, restlessness, trouble concentrating, and intense cravings

    • Nicotine can make existing mental health conditions worse

    • The developing brain is particularly vulnerable to the mood-altering effects of nicotine

  • Social Impact

    Tobacco and nicotine use can affect relationships, school performance, and social life in ways that are easy to overlook at first.

    • Tobacco use is often framed as social, but peer pressure to participate can quickly turn into dependence

    • Nicotine addiction can affect focus, memory, and motivation, impacting academic performance

    • Use of tobacco products can create friction with family and caregivers

    • Students who use tobacco may face disciplinary actions at school

  • Financial Impact

    Tobacco products aren't cheap, and the addiction they create keeps the spending going.

    • Regular use of nicotine pouches, e-cigarettes, or cigarettes can cost hundreds to thousands of dollars per year

    • Disposable vapes and single-use products are particularly expensive relative to how quickly they're used up

    • Underage purchase or possession of tobacco products can result in fines and legal consequences

    • Money spent on tobacco products is money that could be invested in education, savings, or experiences that actually build your future

  • Environmental Impact

    Tobacco products cause damage well beyond the people who use them.

    • Discarded cigarette butts are one of the most common forms of litter worldwide and leach toxic chemicals into soil and water

    • E-cigarette devices, pods, and cartridges contribute to electronic waste

    • E-liquid spills and improperly disposed of devices release harmful chemicals into the environment

    • Many tobacco product components include plastics and metals that do not biodegrade

  • Extracurriculars & Athletics Impact

    For teens involved in sports, performing arts, or other activities, tobacco and nicotine can directly undermine performance and commitment.

    • Nicotine affects lung capacity and cardiovascular performance, making physical activity harder

    • The body's ability to heal and recover from injury is impaired

    • Fatigue and health issues can lead to missed practices, games, or auditions

    • Many athletic organizations test for tobacco/nicotine use and may have eligibility rules
