Is Nicotine Bad for You? What It Does to Your Body

Nicotine pouches look clean. There's no smoke, no ash and no tobacco leaf, just a small white pouch under your lip. But the main ingredient hasn't changed: nicotine. Here is what the research says it does to your body, and what to know before you reach for another tin.

1. Nicotine is highly addictive

The CDC puts it plainly: nicotine is highly addictive. The format doesn't change that. Using pouches every day builds dependence over time, which is how one pouch after lunch can turn into several a day.

2. It speeds up your heart and raises your blood pressure

Nicotine stimulates your sympathetic nervous system, the body's "fight or flight" switch. That releases norepinephrine, which raises your heart rate and blood pressure. A 2020 review of the research describes these effects across different ways of taking nicotine, including nicotine placed under the tongue. The effect is short-lived each time, but daily users repeat it many times a day.

3. It can affect a developing brain

According to the CDC, nicotine can harm brain development, which continues until about age 25. It can affect the parts of the brain that control attention, learning, mood and impulse control. That matters because pouches are popular with young adults, and many users start in their teens or early twenties.

4. Going without it is uncomfortable

Once your body is used to nicotine, missing a dose shows up fast. Common withdrawal symptoms include feeling irritated, anxious and restless, and having trouble concentrating and sleeping. Symptoms can start within a few hours, are usually worst in the first week, and cravings can last for months. For regular users, part of the "lift" a pouch seems to give can simply be relief from that withdrawal.

5. Pouches are dangerous for small children

A study published in Pediatrics in 2025 found a 763% increase in nicotine pouch ingestions among children younger than 6 between 2020 and 2023, based on calls to US poison centers. Compared with other nicotine products children swallowed, pouches were more likely to lead to serious medical effects or a hospital stay. If a child swallows a nicotine pouch, call Poison Control at 1-800-222-1222.

6. It's harmful during pregnancy

The CDC says nicotine is toxic to developing fetuses and can damage a fetus's developing brain and lungs.

"But some nicotine pouches are FDA-authorized"

In January 2025, the FDA authorized the sale of 20 ZYN nicotine pouch products, the first nicotine pouches to get that authorization. The FDA was clear about what that means: it "does not mean these tobacco products are safe." Authorization compares pouches with cigarettes. It doesn't make nicotine harmless.

Want the pouch without the nicotine?

A lot of people like the pouch format itself: it's discreet, there's nothing to drink, and it fits in a pocket. That's why nicotine-free pouches exist.

MVP is one of them. It contains zero nicotine, zero caffeine and zero sugar. Instead, each pouch has 100 mg of paraxanthine, the compound your body makes from caffeine, plus L-theanine, Alpha-GPC and taurine. Read how paraxanthine compares with caffeine. Paraxanthine is still a stimulant, so start with one pouch, and skip it if you're pregnant, nursing or sensitive to caffeine.

MVP is not a quit-smoking product and isn't meant to treat nicotine addiction. If you want to quit nicotine, talk to your doctor, visit smokefree.gov or call 1-800-QUIT-NOW.
