Abstract Background and aims Oral nicotine pouches (ONPs) contain varying proportions of freebase nicotine (FBN), with higher FBN expected to increase nicotine delivery across the oral mucosa. Because ONPs contain fewer toxicants than moist snuff and may serve as a reduced harm alternative for smokeless tobacco, we compared how the FBN in ONPs affects ...
