*
The participant reported smoking marijuana one time during treatment, which fell in the beginning of the 90 days of the TLFB Survey. The participant had not completed the Substance Abuse component at this point in treatment, reported the marijuana use incident to the therapist in the next session, and did not report use since that time (urine analysis was negative at post-treatment as well).
