• Scientists at the National Institute on Drug Abuse Intramural Research Program (NIDA/IRP) studying the effects of cocaine withdrawal on brain opiate receptors are seeking volunteers. Volunteers should be heavy, chronic users of cocaine and in relatively good health.

  This study is being conducted by physicians and psychologists at the NIDA/IRP located in Baltimore, in collaboration with scientists at Johns Hopkins University. Measures of brain opiate receptors are done by positron emission tomography (PET) scans conducted over the course of 13 weeks while volunteers reside on the Clinical Ward as an inpatient. Volunteers are compensated for their participation.

• Scientists at the National Institute on Drug Abuse Intramural Research Program (NIDA/IRP) need volunteers to study how drugs like methamphetamine, cocaine and codeine get into body specimens like hair, nails, and skin. All volunteers should be experienced users of illegal drugs and be willing to live on the Clinical Unit of the IRP for 10 straight weeks.

  This study is being conducted by researchers at the NIDA/IRP located in Baltimore. Volunteers must be willing to provide samples of body specimens (e.g., head hair, nails, skin, urine, sweat, blood, and saliva). Volunteers will be paid for their participation.

• Scientists at the National Institute on Drug Abuse Intramural Research Program (NIDA/IRP) studying cocaine craving are seeking volunteers. Volunteers can be experienced cocaine users or persons who have never used cocaine; all should be in general good health.

  This study is being conducted by psychologists and physicians at the NIDA/IRP located in Baltimore and includes brain imaging (Positron Emission Tomography [PET] and Magnetic Resonance Imaging [MRI]), neuropsychological and cognitive testing, and medical evaluations including blood work, ECG and a complete history and physical examination. The study requires 2 PET scans separated by at least one week and involves an overnight stay at our facility. All volunteers will be compensated for their participation.

• Scientists at the NIDA/IRP, located in Baltimore, are conducting studies to determine if nicotine withdrawal leads to functional changes in specific regions of the brain. Healthy individuals who are either current, heavy smokers, past smokers or non-smokers are needed for the study.

  Volunteers will receive a battery of cognitive tests and undergo a PET scan and MRI scan as part of the study. All participants will also receive a complete physical examination including blood work, electrocardiogram and medical history. Participants will be required to make 7 visits to the NIDA\IRP including 2 PET sessions separated by at least one week. All volunteers are compensated for their participation.

  For more information contact the Recruitment Unit, (410)550-1502 or 1-800-535-8254.
