Current Studies / Marijuana Memory Study

Be a part of a study on memory function in marijuana users

What is this study about?
Marijuana is one of the most widely used substances, but the effects of use on brain function are poorly understood. This study aims to measure brain activity and structural differences between those who have used marijuana long-term and those with no extensive history of use. Our neuroscientists measure brain function by using safe, state-of-the-art neuroimaging technology to measure brain structure, as well as brain activity during a memory test.

What will I do?
Participation in this study and all information collected as part of the study are completely confidential.  You will not be asked to ingest any medications. All procedures are non-invasive and consist of the following:

Clinical Interviews: Conversations with members of the research staff to gather background information.
Neuropsychological Testing: Simple tests of memory, attention, and other thought processes.
Laboratory Tests: A urine sample to document recent use of alcohol or other drugs.
Neuroimaging: Several safe, non-invasive, non-radioactive MRI brain scans will be administered. In one session, the structural scan and maps the brain�s anatomy during rest, the magnetic resonance spectroscopy scan (MRS) measures the brain�s chemicals during rest, and the functional scan (fMRI) maps the brain�s activity while performing a task. The MRI session lasts approximately 1 hour.

Who can participate?
We are looking for 18-22-year-olds who are right handed and either have

  • No history of substantial alcohol or drug use.

  • Community members who use marijuana regularly.

Participation in this research study will help us better understand the effects of marijuana on memory functioning.  Every participant will be compensated $20 an hour upon completion of the study. The entire study lasts approximately 4 hours. There is no charge for any test.

How to Be a Volunteer
