Nicotine pouches
Researchers interviewed 44 regular oral nicotine pouch users to understand how they use these products. Users reported varying habits including where they place pouches in their mouth, how long they keep them in, and whether they use multiple pouches at once—all of which affect how much nicotine they absorb.

Researchers found that when reviewing evidence on e-cigarettes for quitting smoking, one large study (Hajek et al.) overwhelmingly influenced the overall conclusion, potentially distorting the true picture. They propose a new testing method to detect when single studies unfairly dominate systematic reviews, helping policymakers better understand the actual strength of evidence.
