NCT06315881

Brief Summary

This clinical trial evaluates the characteristics of oral nicotine pouches (ONPs) to determine if they are a comparable substitute to cigarette or smokeless tobacco (ST) products. ONPs contain nicotine but no tobacco and are used primarily by adult tobacco uses in the United States (US). ONPs are recognized by the Food and Drug Administration as having lower risk than combustible cigarettes and are approved as a modified risk tobacco product. While ONPs have lower toxic risk than other tobacco products, acute and longer term harm related to their use has not been studied. Information gathered from this study may identify product characteristics of ONPs that improve successful switching from high-risk cigarettes or ST to lower risk ONPs.

Outcome Measures

Primary Outcomes (5)

  • Increased nicotine delivery

    Data will be used to assess the effects of nicotine concentration, form and isomer on the addiction potential and appeal of oral nicotine pouches (ONPs) relative to cigarettes and smokeless tobacco (ST). Generalized mixed effects models will be used to assess differences between the four ONP conditions and the usual product.

    Up to 3 months

  • Liking

    Data will be used to assess the effects of nicotine concentration, form and isomer on the addiction potential and appeal of ONPs relative to cigarettes and ST. Generalized mixed effects models will be used to assess differences between the four ONP conditions and the usual product.

    Up to 3 months

  • Craving/withdrawal suppression

    Data will be used to assess the effects of nicotine concentration, form and isomer on the addiction potential and appeal of ONPs relative to cigarettes and ST. Generalized mixed effects models will be used to assess differences between the four ONP conditions and the usual product.

    Up to 3 months

  • Rate of switching to ONP

    Data will be used to assess the effects of nicotine concentration, form and isomer on the addiction potential and appeal of ONPs relative to cigarettes and ST. Generalized mixed effects models will be used to assess differences between the four ONP conditions and the usual product.

    Up to 3 months

  • Rate of switching to ONPs

    Data will be used to evaluate the effects of nicotine concentration, form and isomer on switching from cigarettes or ST to ONPs either partially or completely. Logistic regression models will be used to examine whether differences in form and isomer significantly impact switching.

    Up to 3 months

Secondary Outcomes (1)

  • ONP and Tobacco Purchase Task

    Up to 3 months
