1. Hazardous drinking and cannabis were reportedly frequent. 
2. In cannabis users, MI participants had scored higher than control group participants on the 10-point readiness to change scale. 
3. There was no difference between groups in type or number of usual care psychiatry clinic visits between intake and six month follow-up
4. No significant effect for the treatment group regarding cannabis use 
MI at three months were less likely than controls to report hazardous drinking.

Results 

1. Intervention session of MI 
2. 2 15-minute telephone sessions 
3. The control group got brochures on substance use and risks specific to the substances they reported
4. 20-minute follow-up interviews during month 3 and 6

California Baptist University

Participants: 
1. People who are 18+ and looking for outpatient services in the Langley Porter Hospital and Clinics (LPPHC) at the University of California, San Francisco (UCSF) Medical Center.
2. Patients are referred by their insurance carrier, self-referred, or referred by the providers in their community. 
3. The study was conducted in the Adult Psychiatric Clinic and Partial Hospitalization Program, two LPPHC programs. 
4. The APC focuses on evaluation, psychotherapy, and medication management for patients with a range of mental health problems.
5. PHP: more intensive outpatient service where patients attend individual and group treatment for 5 hours daily for ten weeks.

Usual depression care:
1. All study participants received usual depression care based on current best practices for medication management and empirically supported forms of individual and group psychotherapy.
2. Treatment decisions were made collaboratively by clinicians and patients.
