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
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:
Conversations with members of the research staff to gather background
Simple tests of memory, attention, and other thought processes.
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 brainís
anatomy during rest, the magnetic resonance spectroscopy scan (MRS) measures
the brainís chemicals during rest, and the functional scan (fMRI) maps the
brainís 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
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.
