Intervention

1. Snow Control in the intervention group is a six week self-help intervention tool to reduce cocaine consumption
2. Snow Control in the intervention group is based on classical cognitive behavioural therapy (CBT) approaches for:
2.1. Cocaine addiction
2.2. Motivational interviewing for cocaine using individuals
2.3. Principles of self control
2.4. Relapse-Prevention Model
3. It is structured into three parts and includes the following eight modules that will be activated for access week by week with three additional voluntary modules (module 5, 6 and 7) that can be activated during week 5-6
4. In the control condition, participants receive 8 psycho-educative information on the risks, potential harms and other important information on their cocaine consumption also in a weekly manner within 6 weeks of intervention. After having read this information they participate in a weekly quiz to control their information knowledge.
5. Follow up will be at 6 months for both groups after the 6 intervention weeks
