The Addictions Unit is currently involved in conducting research aimed at improving services and outcomes for patients. In addition, some studies are being conducted to further understand the genetic, biological and psychological factors that contribute to the development of addiction. Patients attending the Addictions Unit may be asked to participate in one of several ongoing studies. For example patients could be asked to participate in a medication trial, a brain imaging study, or a follow-up study aimed at measuring the outcome of our inpatient detoxification program or the effectiveness of our outpatient addiction treatment program. It is important to note that anyone invited to participate in a study will be given extensive information on the objectives of the research as well as the risks and benefits of participating, and they will be asked to sign an informed consent form. Patients are free to refuse participation, and refusal will not affect treatment in any way.
