Regular use of nicotine pouches causes mouth cancer in users of the product.

Is it true that regular use of nicotine pouches causes mouth cancer in users of the product?

Unclear. The retrieved reviews and reference pages describe oral effects of nicotine pouches as mainly mild and transient, and note that evidence on long-term cancer outcomes for pouches is still lacking; smokeless-tobacco cancer findings are attributed to tobacco-specific nitrosamines, which tobacco-free pouches do not contain. No item directly establishes that regular pouch use causes mouth cancer.
