Strengthening Self-Control Is Better Than a “Quit Date” to Kick the Smoking Habit

The desire to quit smoking — often considered a requirement for enrolling in treatment programs — is not always necessary to reduce cigarette cravings, argues a review of addiction research published July 30TH 2015 in Trends in Cognitive Sciences. Early evidence suggests that exercises aimed at increasing self-control, such as mindfulness meditation, can decrease the unconscious influences that motivate a person to smoke.

A release from the publisher explains that scientists are looking to the brain to understand why setting a “quit day” isn’t a surefire way to rid oneself of a cigarette habit. Recent neuroimaging studies have shown that smokers have less activity in the brain regions associated with self-control, raising questions around whether targeting these neurobiological circuits could be a way to treat addiction.

The release quotes senior study author Nora Volkow, Director of the U.S. National Institute on Drug Abuse, as saying, “We are interested in trying to probe how repeated use of drugs ultimately influences our ability to control our desires. We are starting to work through how drugs affect areas of the brain that normally enable us to self-regulate, to create goals and to be able to achieve them, and how those changes influence the behavior of the person addicted.”

One study highlighted in the review explored how improving self-control can help smokers with their cravings. Texas Tech University and University of Oregon researchers recruited 60 undergraduate students (27 cigarette smokers and 33 nonsmokers) to participate in an integrative body-mind training program that included relaxation training techniques. Each of the students came into the program expecting to learn meditation and relaxation techniques for stress reduction and cognitive improvement. The students were split into two groups so that half received mindfulness meditation training (e.g., becoming self-aware of one’s experience) and half received relaxation technique (e.g., relaxing muscle group).

Before and at the end of 2 weeks, after 5 hours of 30 minute sessions, the students received brain scans, filled out self-report questionnaires, and received objective measure of carbon monoxide on their smoking amounts and habits. Even though many of the students said they smoked the same number of cigarettes before and after the training, for those who received mindfulness meditation, an objective measure of carbon dioxide percentage in their lungs showed a 60 percent reduction in smoking over 2 weeks after the study.

“The students changed their smoking behavior but were not aware of it,” says lead study author Yi-Yuan Tang, a Professor of Psychological Sciences at Texas Tech. “When we showed the data to a participant who said they had smoked 20 cigarettes, this person checked their pocket immediately and was shocked to find 10 left.”
