Nicotine pouches, particularly those like Zyn, have recently gained traction on social media as a purported aid for weight loss, touted as a readily accessible alternative to prescription medications like Ozempic. This trend, sometimes referred to as "gas station Ozempic," raises significant concerns among medical experts, who caution against the potential health risks associated with using nicotine pouches for weight management.
What are Zyn Pouches?
Zyn pouches are small, pillow-like pouches containing nicotine salts and flavorings. They are placed between the lip and gum, allowing nicotine to be absorbed into the bloodstream through the tissues in the mouth. Zyn pouches come in varying nicotine strengths, typically ranging from 3mg to 6mg, and are designed to be kept in the mouth for up to an hour.
The Appeal of Nicotine Pouches for Weight Loss
The appeal of nicotine pouches as a weight-loss aid stems from the belief that nicotine acts as an appetite suppressant. Nicotine can affect appetite in several ways, including altering activity in reward processing brain circuits through stimulating the release of neurotransmitters and influencing the activity of appetite-regulating hormones like leptin and ghrelin. This can make it easier for individuals to reduce their overall calorie intake without experiencing constant hunger or feelings of deprivation, which can be particularly helpful during the initial stages of a weight-loss plan.
The Health Risks of Nicotine Pouches
Despite their potential appetite-suppressing effects, medical professionals strongly advise against using nicotine pouches for weight loss due to the associated health risks.
Short-Term Side Effects
In the short term, nicotine pouches can cause several side effects, especially at higher doses, including:

Long-Term Health Risks
The long-term risks associated with nicotine use are more serious and can include:
- Cardiovascular Issues: Nicotine can have acute cardiovascular effects, such as increasing heart rate and blood pressure, which may pose risks for individuals with underlying cardiovascular conditions. It is also a vasoconstrictive substance, meaning it tightens blood vessels, potentially leading to coronary artery disease, hypertension, heart attack, and stroke.
- Increased Risk of Cancer: Nicotine use is associated with an increased risk of various types of cancer. A 2022 study found that 26 out of 44 nicotine pouch products tested contained cancer-causing chemicals known as tobacco-specific nitrosamines (TSNAs). Oral nicotine products can also contain trace amounts of toxic TSNAs, metals, and formaldehyde.
- Oral Health Problems: Research suggests that nicotine pouches can cause periodontal disease and damage to the gums, potentially leading to tooth loss or decay. A 2023 study found that repeated application of nicotine to the same area of the mouth could lead to periodontitis, the main cause of tooth loss.
- Addiction: Nicotine is a highly addictive substance that can lead to psychological and physiological dependence, as well as withdrawal symptoms upon cessation of use. Nicotine addiction causes strong cravings, a tendency to continue nicotine/tobacco use because it becomes hard to stop, anxiety, sadness, irritability, or trouble sleeping due to withdrawal.
- Neurological Effects: Nicotine changes the brain, leading to the production of more nicotine receptors with each use. When these receptors are empty, the brain signals the need to fill them again, perpetuating the cycle of addiction. The release of dopamine associated with nicotine use can also lead individuals to neglect healthier ways of releasing dopamine, such as exercise, deep breathing, hydration, or meditation.
- Other Side Effects: Nicotine pouches can also lead to anxiety, irritability, insomnia, and mouth sores from the pouches breaking down mucus membranes in the mouth.
Nicotine Pouches vs. Other Nicotine Replacement Products
While nicotine pouches may seem similar to FDA-regulated smoking cessation products like nicotine lozenges, gum, patches, or nasal sprays, there are critical differences. Nicotine pouches are not FDA-regulated, meaning that the exact amount of nicotine and other additives they contain is unknown. This lack of regulation raises concerns about the potential for users to consume even more nicotine than they would from cigarettes.
Debunking Myths About Nicotine and Weight Loss
Many people erroneously believe that nicotine suppresses appetite and increases metabolic rate. However, experts argue that nicotine does not suppress appetite. People attempting to quit smoking or using nicotine substances often gain weight because they replace the craving for nicotine with food. While nicotine may increase heart rate due to its vasoconstrictive properties, potentially boosting metabolic rate, this effect is not proven and poses dangers for individuals with heart or circulatory issues.
FDA Authorization of Certain ZYN Products
The Food and Drug Administration (FDA) authorized the marketing of 20 ZYN nicotine pouch products through the premarket tobacco product application (PMTA) pathway following an extensive scientific review. The FDA determined that these specific products met the public health standard legally required by the 2009 Family Smoking Prevention and Tobacco Control Act, considering the risks and benefits of the products to the population as a whole.
The FDA's evaluation showed that the authorized products pose a lower risk of cancer and other serious health conditions than cigarettes and most smokeless tobacco products due to substantially lower amounts of harmful constituents. The applicant also provided evidence from a study showing that a substantial proportion of adults who use cigarette and/or smokeless tobacco products completely switched to the newly authorized nicotine pouch products.

However, the FDA emphasized that these authorizations are specific to the 20 ZYN products that underwent science-based review and received marketing authorizations by the agency. The FDA has not approved nicotine pouches as safe, nor has it approved them for smoking cessation. The agency will closely monitor the marketing and use of these products and may suspend or withdraw a marketing granted order if the continued marketing of a product no longer meets the necessary public health standard.
Healthier Alternatives for Appetite Suppression and Weight Loss
Instead of resorting to nicotine pouches or other potentially harmful substances, there are several healthy, natural ways to regulate appetite and manage weight:
- Hydration: Drinking plenty of water can help reduce hunger, as thirst is often confused with hunger.
- Fiber Intake: High-fiber foods like fruits, vegetables, whole grains, and legumes can keep you feeling fuller for longer periods.
- Protein Intake: Protein-rich foods can have a similar effect, helping to enhance satiety and reduce overall food intake.
- Mindful Eating: Paying close attention to what and how much you’re eating can help you recognize fullness cues better and prevent overeating.
- Regular Exercise: Physical activity can help regulate appetite hormones and reduce the feeling of hunger.
- Specific Foods:
- Oats: Packed with soluble fiber, which slows digestion and keeps you feeling fuller longer.
- Apples: High in fiber and water, keeping you full and hydrated.
- Eggs: Protein-rich and help enhance satiety.
- Avocados and Nuts: High in healthy fats, which can promote feelings of fullness.
- Water-Rich Vegetables: Cucumbers, zucchinis, and bell peppers have a high water and fiber content, which can help to fill you up.
Addressing Emotional Eating
It’s important to remember that we eat for various reasons, not just because we’re hungry. Factors like stress, boredom, emotional comfort, and social gatherings can trigger eating. Therefore, while controlling hunger through appetite suppression can help, it’s also crucial to address and manage these other factors. Developing a healthy relationship with food, recognizing emotional eating triggers, and finding non-food methods to cope with emotions or stress are equally important for long-term weight management.
The Importance of a Calorie Deficit
A fundamental principle of weight loss is creating a calorie deficit, meaning you burn more calories than you consume. This can be achieved by either eating fewer calories or burning more calories through exercise. Creating a 500-calorie daily deficit can lead to 1 to 3 pounds of weight loss per week. Consuming proper nutrients through a balanced diet is essential for healthy and sustainable weight loss.
Releasing Dopamine Naturally
People who use nicotine to release dopamine need to re-learn how to get a dopamine release from other sources. Simple acts like drinking a glass of water, practicing deep breathing or meditation, hugging someone, or exercising will release dopamine. Establishing a cause-and-effect relationship between exercising and this positive feeling is crucial.

Concerns Regarding Teenage Use of Zyn
The increasing popularity of Zyn among teenagers is a cause for concern. With schools cracking down on vaping and smoking, teens may turn to Zyn as a more discreet way to alleviate nicotine withdrawal symptoms. The appealing flavors and discreet nature of Zyn, combined with its promotion on social media, make it particularly attractive to young people.
Nicotine poses cardiovascular risks for teens, increasing heart rate, blood pressure, and oxygen consumption of the heart. It can also negatively affect sleep, an area where teens are already struggling with the rise of screen time and social media. Moreover, studies have shown that teens who use e-cigarettes are more likely to start using regular cigarettes as they get older.
Recognizing Zyn Use in Teens
Parents and caregivers should be aware of the signs that their teen may be using Zyn, including:
- Finding small, white pouches in their mouth or belongings.
- Discovering round containers that look like mint containers.
- Noticing a decreased appetite or weight loss.
- Observing mood swings, irritability, agitation, or anxiety.
- Seeing them disappear in a suspicious way or for prolonged periods.
Communicating with Teens About Zyn
Communication is key to addressing the issue of Zyn use among teenagers. Parents should initiate conversations with their teens about the risks of Zyn and other nicotine/tobacco products, approaching the conversation with curiosity rather than accusation. It is important to listen and seek to understand their perspective, prepare them for peer pressure, set clear expectations, and create a nicotine/tobacco-free home environment.
If you discover your teen is using Zyn or other nicotine/tobacco products, it is best to have a conversation with the goal to help, not to blame. Assess whether they have a nicotine addiction and consult their pediatrician or family doctor for support and guidance.
