Brain Imaging of Cocaine Craving in Recreational Cocaine Users

Completed

Conditions studied: Cocaine Related Disorders

In brief

The purpose of this study is to compare individuals with cocaine dependence to recreational users of cocaine in terms of their brain reactivity to cocaine cues, in hopes that this comparison may help us better understand the transition from recreational to compulsive cocaine use.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subjects must be able to provide informed consent and function at an intellectual level sufficient to allow accurate completion of all assessment instruments.
• Subjects must report having used cocaine within the past 3 months. Subjects may meet criteria for abuse, but not dependence on any other substance with the exception of nicotine, marijuana and alcohol.
• Use of one of the following methods of birth control by female subjects: birth control pills, barrier methods (diaphragm or condoms with spermicide or both), surgical sterilization, use of an intra-uterine contraceptive device, or complete abstinence from sexual intercourse.
• Subjects must live within a 50-mile radius of the research facility and have reliable transportation.
• Subjects must consent to remain abstinent from all drugs of abuse (except nicotine) prior to the experiment.
• Subjects must be right-handed.

You may not qualify if…

• Women who are pregnant, nursing or of childbearing potential and not practicing an effective means of birth control.
• Subjects with evidence of or a history of significant hematological, endocrine, cardiovascular, pulmonary, renal, gastrointestinal, or neurological disease including diabetes, as these conditions may affect heart rate or skin conductance measurement.
• Subjects with a history of or current psychotic disorder as this may impact cue reactivity.
• Subjects who are unwilling or unable to maintain abstinence from alcohol and other drugs of abuse (except nicotine).
• Subjects meeting DSM-IV criteria for substance dependence (other than nicotine, marijuana, or alcohol) within the past 60 days. Subjects may not meet criteria for cocaine dependence at any time.
• Subjects currently taking B-blockers, anti-arrhythmic agents, psychostimulants or any other agents known to interfere with heart rate and skin conductance monitoring.
• Subjects with a history of epilepsy or seizure disorder.
• Subjects with significant liver impairment.
• The need for maintenance or acute treatment with any psychoactive medication including anti-seizure medications which could potentially interfere with fMRI.
• Clinically significant psychiatric or medical problems that would impair participation or limit ability to participate in scan.
• Persons with ferrous metal implants or pacemaker since fMRI will be used.
