Measure
3mg Nicotine Concentration
15 participants will be randomly assigned to receive ZYN Pouches with 3mg nicotine concentration. ZYN: 30 current non-treatment seeking adult smokers will be switched from smoking cigarettes to ZYN oral nicotine pouches containing either 3mg or 6mg concentration nicotine salts.
6mg Nicotine Concentration
15 participants will be randomly assigned to receive ZYN Pouches with 6mg nicotine concentration. ZYN: 30 current non-treatment seeking adult smokers will be switched from smoking cigarettes to ZYN oral nicotine pouches containing either 3mg or 6mg concentration nicotine salts.

SECONDARY outcome

Timeframe: week 4

Population: This measure was not used in the study and therefore data were not collected.

To evaluate the acceptability of switching, participants will also be asked how likely it is that they will continue to use ZYN oral nicotine patches for cigarette substitution compared to cigarettes on a question designed for this trial.
