| Additional information regarding sample selection. | All patients between 13 and 18 years old requesting a “cannabis consultation” are seen by the research psychologist. After checking the inclusion criteria, the psychologist proposes the study to the patient and his/her family. If required, they may be given time to think about it and give their answer during a second consultation with the research psychologist. After reading the information sheet and signing their consent, the family is included in the randomised study and assigned to one of three therapies. The randomisation procedure is required by the European protocol.. The Urn Randomisation procedure is used (Stout 1994; Project Match). This is carried out by the research psychologist. |
