Oral nicotine pouches are placed between the gum and lip, allowing nicotine absorption through the oral mucosa (aka: the gums). They typically contain high levels nicotine, flavorings, and other additives. Unlike traditional smokeless tobacco products, nicotine pouches do not contain tobacco leaf.
Nicotine pouches don’t contain tobacco leaf or smoke, so they avoid the harms from inhaling burned tobacco. But that doesn’t make them completely safe. Nicotine is highly addictive. It can raise your heart rate and blood pressure and put strain on your heart.
Nicotine also changes how teen brains develop. It can affect memory, attention, and learning, and may increase the risk of addiction to other substances later on. Scientists are still studying the long-term effects of nicotine pouches.
Nicotine salts, also known as e-liquids, are a form of nicotine not naturally found in tobacco leaves. They are created by combining nicotine with acid. They are chemically altered to be more stable and less harsh when inhaled, allowing for higher concentrations of nicotine to be delivered more smoothly. This modification enables users to inhale higher levels of nicotine.3
Because they deliver higher nicotine concentrations more efficiently, nicotine salts may increase the potential for greater addiction.
Nicotine exposure during adolescence can disrupt brain development, impacting areas responsible for attention, learning, and impulse control. The adolescent brain is particularly vulnerable, and nicotine can cause long-term structural and functional changes.4
Yes, nicotine can increase heart rate and blood pressure, potentially leading to cardiovascular issues. While nicotine pouches don’t involve inhaling smoke or vapors, the nicotine itself poses risks to heart health.
The brain doesn’t fully develop until around age 25. Nicotine changes brain chemistry in ways that last long after the nicotine is gone.
Nicotine hijacks the brain’s reward system, flooding it with dopamine, a feel-good reward chemical. Over time, the brain relies on nicotine for pleasure, motivation, and focus. That’s why young people who use nicotine often feel more anxious, irritable, or unfocused when they don’t have it.
The prefrontal cortex, responsible for decision-making and impulse control, develops last. Nicotine interferes with this process, making it harder to focus, learn, and manage emotions.
The brain adapts to regular nicotine exposure, changing how it responds to stress, mood, and cravings. These changes can make quitting harder and increase the risk of addiction to other substances. Nicotine holds the brain hostage and it’s harder to make your own feel-good chemicals without it.
