The Addictions Research Center (ARC) at Dartmouth College is conducting a study using magnetic resonance imaging (MRI) of the brain to explore:





· The differences in the brains of people who smoke marijuana and those who don't smoke



· The short-term effects of marijuana on the brain







Each year, more states have legalized marijuana for medical or recreational purposes. It is more important than ever to understand how marijuana and brain affect each other. We need your help to complete this study.





People in this study will be paid for their participation. If you smoke marijuana and would be interested in helping with this study, then answer a few questions to see if you might qualify. Your answers will be kept confidential. Or, if you prefer to speak to us about the study please contact our study staff at 1 (877) 491-4451.
