Intervention(s)

Integrated smoking cessation and binge drinking intervention
1. Individually tailored mobile phone text messages to support smoking cessation and addressing (a) the risks of smoking, (b) the monetary costs of smoking, (c) the social norms of smoking, (d) outcome expectancies, (e) motivation to reduce cigarette consumption, (f) motivation to use social support for smoking cessation, (g) strategies to cope with craving situations, (h) tips for preparing for smoking cessation, (i) reward for staying abstinent. Participants will receive two weekly text messages over a time period of 3 months.
2. Possibility to register for a more intensive program providing strategies for smoking cessation around a self-defined quit date. Participants will receive one or two text messages per day for a period of 4 weeks.
3. Web-based feedback including individually tailored information on (a) the number of drinks consumed per week in relation to the age- and gender-specific reference group, (b) financial costs of drinking, (c) calories consumed with alcoholic drinks, and (d) number of binge drinking occasions in relation to the age- and gender-specific reference group.
The participants will receive a single web-based feedback immediately after the baseline assessment.
4. Individually tailored mobile phone text messages to stimulate drinking within low-risk limits. Only participants with binge drinking (five or more drinks on one occasion in the last 30 days for male and four or more drinks on one occasion in the last 30 days for female participants) at the baseline assessment will receive these messages (one message per week) over a time period of 3 months.


Smoking cessation only intervention
1. Individually tailored mobile phone text messages to support smoking cessation and addressing (a) the risks of smoking, (b) the monetary costs of smoking, (c) the social norms of smoking, (d) outcome expectancies, (e) motivation to reduce cigarette consumption, (f) motivation to use social s

Primary Outcome(s)

1. 7-day point prevalence smoking abstinence (i.e., not having smoked a puff within the past 7 days) assessed at 6-month follow up
2. Cigarette consumption assessed at 6-month follow up (number of cigarettes smoked on a typical day for daily smokers, typical number of smoking days per month and number of cigarettes smoked on a typical smoking day for occasional smokers)

Secondary Outcome(s)

1. 30-day point prevalence smoking abstinence (i.e., not having smoked a puff within the past 30 days) assessed at 6-month follow up
2. Stage of change according to the Health Action Process Approach (Schwarzer et al. 2008, Applied Psychology) assessed at 6-month follow up
3. Quit attempt within the previous 6 months assessed at 6-month follow up
4. Alcohol consumption assessed at 6-months follow up by a 7-day drinking calendar for which participants are asked to think about a typical week in the past month and, for each day, to record the number of standard drinks they typically consume on that day.
