Nicotine is the proof that mouth-absorbed delivery works. A pouch parks under your lip and some goes straight into your blood through your gums.
A small, fat-friendly molecule that crosses the thin skin inside your mouth on its own - no special helper needed. That is why pouches, gum and lozenges work and why swallowing it does not.
THE PROOF OF CONCEPT for buccal delivery. 40+ years of ZYN/NRT clinical data. ~95% bioavailability via pouch/lozenge. Entire buccal delivery industry built on this pharmacokinetic foundation.
