The evidence base around oral nicotine pouches is expanding quickly. An updated scoping review published in Nicotine & Tobacco Research in September 2026 identified 73 new studies since an earlier review, examining areas including product characteristics, patterns of use, perceptions, toxicity, nicotine delivery, sales and marketing.
The findings provide a more developed picture of the category, but they also reinforce the need for careful interpretation. Evidence increasingly supports important differences between nicotine pouches and combustible cigarettes, while questions remain around long-term health effects, youth uptake and patterns of continued or dual use.
Lower Toxicity Does Not Mean No Risk
One of the review’s important findings concerns relative toxicity. The authors concluded that oral nicotine pouches are considerably less toxic than cigarettes, although their long-term health effects remain understudied.
This distinction matters when communicating nicotine risk. Cigarette smoking exposes users to products of combustion, which account for much of the serious disease associated with smoking. Tobacco-free nicotine pouches do not involve combustion, but avoiding combustion does not make them harmless.
A risk-proportionate approach therefore needs to hold two ideas at the same time: nicotine pouches should not be presented as risk-free, but neither should their risks automatically be treated as equivalent to those of combustible cigarettes.
Nicotine Delivery Varies With Product Strength
The review also examined nicotine delivery. It found that nicotine uptake generally increased with pouch strength and that higher-strength products could produce nicotine exposure exceeding that from cigarettes among adult smokers.
At the same time, nicotine pouches received lower positive subjective ratings than cigarettes in the studies reviewed.
These findings illustrate why product standards are an important part of nicotine pouch regulation. Policymakers need evidence on nicotine content, formulation and delivery rather than relying solely on the presence of nicotine as the basis for regulation.
Clear standards can help address excessive nicotine delivery while providing manufacturers and consumers with predictable rules.
Smoking Reduction and Dual Use Require Further Study
Preliminary evidence reviewed by the authors suggests that nicotine pouch use can reduce cigarette consumption among daily smokers. However, the available short-term studies generally found dual use rather than complete switching away from cigarettes.
That distinction is important.
Reducing cigarette consumption may change exposure, but the greatest potential reduction in smoking-related harm would be expected when combustible tobacco use stops completely. Longer-term studies are therefore needed to understand whether people who initially use both products eventually switch completely, continue dual use or return exclusively to smoking.
Youth Uptake Remains a Legitimate Regulatory Concern
The review also identified increasing use among young people in US surveillance data. Estimates differed between datasets, with current use reported at 1.8% among middle and high school students in the 2024 National Youth Tobacco Survey and 2.6% among 10th and 12th graders in Monitoring the Future.
These findings support strong age restrictions and responsible marketing standards.
Protecting young people and recognising differences in risk between nicotine products are not competing objectives. Regulation can restrict youth access and inappropriate marketing while preserving accurate information for adults about the substantial differences between combustible and non-combustible products.
A Growing Evidence Base Still Has Important Gaps
The updated review demonstrates how rapidly nicotine pouch research is developing. It also shows why definitive claims in either direction remain premature.
Long-term health outcomes remain insufficiently studied. More evidence is needed on complete switching from cigarettes, sustained dual use, effects among people who previously did not use nicotine, and the population-level consequences of growing nicotine pouch availability.
For GINN, the regulatory implication is straightforward: policy should evolve with the evidence. Product standards, youth protections and responsible marketing controls can address identifiable risks, while relative-risk differences between combustible cigarettes and non-combustible nicotine products should remain visible in public-health policy.
As the evidence base grows, maintaining that distinction will be essential to proportionate nicotine regulation.
