Crushing virtual cigarettes reduces nicotine dependence

Oct 28 2009

Smokers who crushed computer-simulated cigarettes as part of a psychosocial treatment program in a virtual reality environment had significantly reduced nicotine dependence and higher rates of tobacco abstinence than smokers participating in the same program who grasped a computer-simulated ball, according to a study described in the current issue of CyberPsychology and Behavior, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com). The article is available free online at www.liebertpub.com/cpb

Benoit Girard, MD, Vincent Turcotte, and Bruno Girard, MBA, from the GRAP Occupational Psychology Clinic (Quebec, Canada), and St-phane Bouchard, PhD, from the University of Quebec in Gatineau, randomly assigned 91 smokers enrolled in a 12-week anti-smoking support program to one of two treatment groups. In a computer-generated virtual reality environment, one group simulated crushing virtual cigarettes, while the other group grasped virtual balls during 4 weekly sessions. The authors document the results in the article "Crushing Virtual Cigarettes Reduces Tobacco Addiction and Treatment Discontinuation."

The findings demonstrate a statistically significant reduction in nicotine addiction among the smokers in the cigarette-crushing group versus those in the ball-grasping group. Also, at week 12 of the program, the smoking abstinence rate was significantly higher for the cigarette-crushing group (15%) compared to the ball-grasping group (2%).

Other notable findings include the following: smokers who crushed virtual cigarettes tended to stay in the treatment program longer (average time to drop-out > 8 weeks) than the ball-grasping group (< 6 weeks). At the 6-month follow-up, 39% of the cigarette crushers reported not smoking during the previous week, compared to 20% of the ball graspers.

"It is important to note that this study increased treatment retention. All too often individuals drop out of treatment prior to completion. It will be interesting now to go further and compare this to other popular treatments such as the nicotine patch," says Brenda K.
