简要总结
This study will determine whether a range of products along the reduced-risk continuum can reduce smoke exposure for individuals who fail to quit smoking using current medically approved nicotine replacement therapy (NRT) products. The strategy will be to offer 325 smokers four weeks of NRT of their choice (gum, lozenge, or nicotine patch) and assess them for quit-smoking status at the end of the period. Seven-day point abstinence will be used to determine responder status at the end of the four-week period (CO of <6 ppm at both CO collection points during that seven-day period and self-report of no smoking during that seven-day period). Those who have not quit, and who therefore have a very low chance of later success (a consistent finding in prior studies and to be verified in the proposed study), will be randomly assigned to either receive a potential "rescue" product (nicotine pouch or ENDS (electronic nicotine delivery system), or remain on NRT (control group).
