Nicotine mouth pouches are smokeless products placed under the lip to release nicotine without burning tobacco. They do not produce smoke or vapor, but they still deliver an addictive substance. Possible effects include gum irritation, nausea, increased heart rate, and dependence. Long-term nicotine use can affect brain development in teens and raise health risks. These products are intended only for adults and are not risk-free alternatives. Avoid use if you are underage, pregnant, or sensitive to nicotine. Staying informed helps you make safer, healthier choices and avoid habits that can harm your body over time.
