Abstract
INTRODUCTION:
This study examined changes in smokers' readiness and confidence to quit
smoking, smoking behavior, nicotine withdrawal symptoms, and tobacco product
preference following electronic cigarette (EC) experimentation and 1 week of ad
libitum use.
METHODS:
Current cigarette smokers, with no prior use of ECs and uninterested in
quitting, completed 3 study phases: baseline assessment (N = 20),
experimentation (N = 19), and ad libitum use (N = 16). Baseline assessment
consisted of completion of assessment measures and exhaled carbon monoxide
measurements. Experimentation phases consisted of four, 75-min sessions in which
participants completed assessment measures and sampled 3 EC brands and their own
brand of cigarette (OBC). Ad libitum use included participants selecting and
being provided their preferred EC brand from the experimentation phase to be
used "as you want" for 1 week. Outcome measures included readiness and
confidence to quit smoking, nicotine withdrawal symptoms, product
preference/satisfaction, and smoking behavior items.
RESULTS:
Readiness and confidence to quit increased significantly during the
experimentation period and continued to increase during ad libitum use. There
were no significant differences in reported effectiveness in reducing smoking
urges and cravings between OBC and EC though OBC were rated as more enjoyable
and satisfying. During ad libitum use, regular cigarette smoking decreased by
approximately 44% from baseline levels with overall tobacco use (EC + OBC)
remaining the same.
CONCLUSIONS:
Among a small convenience sample of unmotivated cigarette smokers, EC
experimentation and 1 week of ad libitum use increased readiness and confidence
to quit regular cigarettes and reduced regular cigarette smoking.
