- Karin Legert's Karolinska Institute study of 272 adults aged 18–30 found gingival recession in 45% of nicotine pouch users, 52% of snus users, and just 6% of non-users.
- The gum recession typically appeared at the exact site where users placed the pouch or snus under their top lip.
- Nicotine pouches appeared to cause more gum irritation (redness, discomfort) than snus, with researchers pointing to flavoring—especially minty varieties containing synthetic cooling agents—as a likely driver.
- Legert cautioned that the absence of tobacco 'should not be interpreted as evidence of long-term safety,' even though it eliminates exposure to tobacco-specific carcinogens.
- Gita Gale at the University of Gothenburg noted that 'almost all tobacco-free pouches sold in Sweden derive from tobacco leaves' and observed users struggled to quit even when reporting high discomfort.
- Nicotine pouch use in Britain rose tenfold, from 0.1% of adults in 2020 to 1% in 2025, the first years they were widely available in the US and UK.
Why it matters: With nicotine pouch use in Britain climbing tenfold from 0.1% to 1% of adults between 2020 and 2025, the Karolinska findings suggest a rapidly growing user base faces a 45% gum recession rate—nearly matching snus. The mint flavorings and synthetic cooling agents that fuel adoption may themselves be causing irritation, complicating the 'tobacco-free = safe' marketing pitch.
