Treatment development, implementation, and participant baseline characteristics: A randomized pilot study of a...

Approximately 57,000 dual users of cigarettes and e-cigarettes call state tobacco quitlines in the U.S. each year.

This paper describes a behavioral intervention for dual users of cigarettes and e-cigarettes designed to increase cigarette abstinence. It also presents baseline data from a randomized pilot comparing the Enhanced E-cigarette Coaching (EEC) intervention with quitline treatment as usual (TAU). Oklahoma Tobacco Helpline callers were recruited at registration and randomized to EEC (n = 46) or TAU (n = 50). Treatment included 5 coaching calls and free nicotine replacement therapy (NRT). EEC treatment included enhanced e-cigarette assessment, education, a shared decision-making quit plan development approach, and tailored behavioral support.

Participants averaged 40.6 years of age and 19.2 cigarettes per day; 85% smoked daily, 48% vaped daily, and 53% reported medium to high e-cigarette dependence. Most reported using e-cigarettes to quit (43%) or to cut down (26%) on smoking. Most had previously tried to quit smoking (91%) and had tried FDA-approved cessation medications (79%). Beliefs about vaping, NRT, and smoking included misinformation. After discussing the relative risks of NRT, vaping, and smoking, most EEC participants (89%) selected a quit plan that incorporated both NRT and vaping.

At baseline, most participants reported a history of failed quit attempts with NRT and were vaping to quit or cut down on smoking, but they may need more support to completely quit smoking. If the EEC improves smoking outcomes, it would provide needed guidance on behavioral support best practices for individuals who vape and want to quit smoking.
