Primary Outcome Measures

Name	Time	Method
<p>Mean number of smoked cigarettes a daythree months after tDCS treatment, as<br /><br>measured by means of EMA for one week<br /><br><br /><br>Mean craving a day three months after tDCS treatment, as measured by means of<br /><br>EMA for one week<br /><br><br /><br>Behavioral and electrophysiological responses to risk-taking and inhibitory<br /><br>control directly before and after the tDCS treatment week. These measures of<br /><br>inhibitory control can be assessed during NoGo trials on the Go/NoGo task. Mean<br /><br>number of pumps on the BART task will represent risk-taking. Positive and<br /><br>negative feedback during the BART task can be used to study<br /><br>electrophysiological responses (See paragraph 8.3 page 17 of protocol).<br /><br><br /><br>Number of cigarettes (and craving) per day starting on the first tDCS day until<br /><br>one week after the last tDCS intervention (total of 14 days) to study the<br /><br>course of cigarette consumption during and after tDCS.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Levels of carbon monoxide on the days that subjects are visiting the Erasmus<br /><br>Behaviors Lab, to control for EMA logged number of cigarettes.<br /><br><br /><br>Furthermore, the following control variables will be assessed: positive- and<br /><br>negative affect, alcohol/ drug use, life satisfaction, amount of drug use in<br /><br>the past month, starting age of using drugs and current age.</p><br>
