Primary Outcome Measures:
  • Change in Cocaine Use by Self Report [ Time Frame: 12 weeks ]
    Self-reports of substance use will be documented at each contact via the Substance Use Calendar. Similar to the Form-90 and the Time Line Follow-Back, which have been shown to be reliable and valid instruments for monitoring substance use and other outcomes in longitudinal studies202-204, the Substance Use Calendar allows a flexible, continuous evaluation of substance use on a daily basis.

  • Change in Cocaine Use by Urine Toxicology Results [ Time Frame: 12 weeks ]
    We will use the Roche onsite TESTCUP system for detection of cocaine, methamphetamine, THC, benzodiazepenes, and opioids.
