The functional overlap of smoking and problem drinking has led researchers to speculate on the need for integrated treatment models. What of online services? With the burgeoning growth of Web-based interventions for smokers and the increasingly common online services for problem drinkers, there is the potential to provide options for smokers to also deal with any alcohol concerns. The integration of these services might also help increase smoking cessation rates, because alcohol consumption is a known trigger to smoking and also for relapse to smoking. This paper presents results of the use of an online personalized feedback assessment for drinking (Check Your Drinking, CYD) by smokers who were recruited from the Stop Smoking Center (SSC; www.stopsmokingcenter.net). Registered users of the SSC (N= 7,741) were invited to complete the CYD (now located as part of an online alcohol reduction program freely available at www.alcoholhelpcenter.net). A total of 963 SSC users responded to the invitation, providing information about their drinking as well as a summary of their current smoking and past experiences of alcohol functioning as a trigger for smoking. One-third of current daily smokers were problem drinkers (24% of occasional smokers and 22% of former smokers were current problem drinkers). Most (82%) daily smokers who were current drinkers reported they frequently or always experienced a strong urge, desire or thoughts about smoking when they drank alcohol. This brief report will explore the implications of the overlap of smoking and drinking by these online participants and will discuss the potential benefits of providing an integrated service for smokers and problem drinkers.
