Intensive Longitudinal Study of the Relationship Between Cigalike E-cigarette Use and Cigarette Smoking among adult Cigarette Smokers Without Immediate Plans to quit Smoking.

Introduction:
This text is a summary of the study "Intensive Longitudinal Study of the Relationship Between Cigalike E-cigarette Use and Cigarette Smoking among adult Cigarette Smokers Without Immediate Plans to quit Smoking" published in Nicotine & Tobacco Research. The study investigated the relationship between the provision of cigalike e-cigarettes and cigarette smoking among adult smokers who were not immediately interested in quitting. The study used a mixed-methods intensive longitudinal design with ecological momentary assessments (EMas) to collect data on cigarette consumption and e-cigarette use.

Key Points:

* The study provided participants with cigalike e-cigarettes and asked them to use them for 21 days.
* Participants reported cigarettes per day, e-cigarette puffs per day, and e-cigarette satisfaction using text-message-based surveys.
* The study found that providing e-cigarettes to smokers who did not intend to quit reduced their cigarette smoking on days when they used e-cigarette more frequently.
* however, this relationship did not hold for menthol smokers.
* Satisfaction with e-cigarette use was predictive of continued use 30 days later.
* a greater amount of cigalike e-cigarette use resulted in less smoking among adult daily smokers without immediate plans to quit, but a lack of nicotine delivery and satisfaction for these devices may have limited their utility as a replacement for cigarette smoking.
* The global concept of "satisfaction" may be an important driver of e-cigarette use among adult smokers.

Main Message:
The study suggests that providing e-cigarettes to adult smokers who are not immediately interested in quitting can reduce their cigarette smoking, but the utility of these devices as a replacement for cigarette smoking may be limited by a lack of nicotine delivery and satisfaction. The study also highlights the importance of satisfaction as a driver of e-cigarette use among adult smokers. Regulators should consider these findings when developing policies related to e-cigarettes.
