New research from Linköping University in Sweden has revealed that individuals who stop using snus—a smokeless, often tobacco-free nicotine product—may experience a significant rise in blood pressure and noticeable weight gain.
The study, published in the Harm Reduction Journal, involved 33 participants aged 18 to 70 and offers a new perspective on the health implications of quitting snus.
Key Findings at a Glance:
- Average blood pressure increased by 3.7 mm Hg after snus cessation.
- Participants gained an average of 1.8 kg (4 pounds) over 12 weeks.
- These changes occurred even though participants had normal blood pressure at the start.
- The increase in blood pressure remained consistent over a two-month period.
These unexpected results suggest that stopping snus use may temporarily disrupt cardiovascular stability, especially in individuals already managing heart or blood pressure conditions.
Why This Matters for Your Health
Nicotine, even when consumed without tobacco, is a stimulant that causes immediate spikes in heart rate and blood pressure. When users stop abruptly, the body may react in unforeseen ways—one being a sustained rise in blood pressure. According to Professor Fredrik Nyström, who led the study, this spike is comparable to the effect of consuming large amounts of liquorice, which is known to elevate blood pressure as well.
Who Is Most at Risk?
The study primarily involved healthy adults, two-thirds of whom were men. Despite the generally good baseline health of participants, the physiological effects of snus withdrawal were still significant. This raises concerns for people with existing cardiovascular risks.
Healthcare providers should be especially cautious when advising snus users to quit, ensuring follow-up monitoring for:
- Systolic blood pressure levels
- Unintended weight gain
- Overall cardiovascular function
Healthy Tips for Those Quitting Snus
If you’re trying to quit snus or planning to support someone who is, consider these proactive health tips:
Regular Blood Pressure Monitoring
Check your blood pressure daily for at least the first month after quitting. Home monitors can be helpful for tracking changes.
Healthy Weight Management
Maintain a balanced diet rich in whole foods and consider increasing physical activity to offset potential weight gain.
Gradual Cessation with Medical Support
Instead of quitting abruptly, consult a healthcare provider for a personalized cessation plan. Nicotine replacement therapies or behavioral counseling may help smooth the transition.
Hydration and Sleep
Proper hydration and 7–9 hours of quality sleep per night can aid in regulating metabolism and mood swings often associated with withdrawal.
Watch for Symptoms of High Blood Pressure
These include headaches, dizziness, chest pain, or blurred vision. Report any of these to your doctor promptly.
Still, this study adds to growing evidence that nicotine—even when tobacco-free—can have lasting effects on the cardiovascular system. As such, health professionals and individuals alike should proceed carefully when discontinuing snus, treating it not as a harmless habit but as a product with real physiological consequences.
