Ada has been trying to stop her heroin use on her own, but muscle and bone pain, insomnia, vomiting, and other withdrawal symptoms have caused her to repeatedly relapse. Dr. Hirsch is holding a clinical trial combining pharmacological and behavioral interventions for the treatment of heroin. The doctor explains the trial and the possible effects.
Ada asks questions about the study, demonstrates her understanding of the procedures, signs and dates the consent form for the study.
