The study titled, “Electronic Cigarette Use and Cigarette Abstinence Over Two Years among U.S. Smokers in the Population Assessment of Tobacco and Health Study,” aimed to determine the relationship association between vaping and smoking cessation in a nationally representative cohort of U.S. smokers.
“..daily but not non-daily e-cigarette use was associated with higher odds of prolonged cigarette smoking abstinence over two years, compared to no e-cigarette use. Daily use of e-cigarettes may help some smokers to stop smoking combustible cigarettes.”
Data about the selected participants was extracted from Waves 1 to 3 of the PATH study, and their tobacco related behaviour was monitored for two years. The researchers led by Dr. Sara Kalkhoran, from the Tobacco Research and Treatment Center at Massachusetts General Hospital, found that daily e-cigarette use at Wave 1 was associated with higher odds of prolonged cigarette smoking abstinence at Waves 2 and 3, compared to non-use of e-cigarettes.
On the other hand non-daily use of e-cigarettes was not associated with successful smoking cessation. Additionally, amongst daily e-cig users in Wave 1, 63% were using e-cigarettes at Wave 3.
The researchers concluded that “daily but not non-daily e-cigarette use was associated with higher odds of prolonged cigarette smoking abstinence over two years, compared to no e-cigarette use. Daily use of e-cigarettes may help some smokers to stop smoking combustible cigarettes.”
