Internet Survey of Cannabinoid Experiences in OCD

Purpose and Overview

The purpose of this study is to learn more about the experiences of individuals with obsessive-compulsive disorder (OCD) who have used marijuana (cannabis) or other substances related to the marijuana plant called cannabinoids, such as cannabidiol (CBD). This study may help us to understand more about how these substances affect people who suffer from OCD so that we may improve OCD treatments in the future. You are being asked to participate because you are more than 18 years old, report having symptoms of OCD, and have used marijuana or cannabinoids in the past.


Participation in this research study is voluntary. You are under no obligation to participate and may decline participation at any time. If you are interested, you will have the option to be contacted about other studies from our group.

Alternative Treatments/Alternatives to Participation

This is not a treatment study. Information being collected is for research purposes only and will not provide information that will be medically useful for you. The alternative to participating would be simply not to participate.

You do not have to participate in this study to receive treatment for OCD. Recommended treatments include medicines called serotonin reuptake inhibitors (SRIs) or a form of cognitive-behavioral therapy (CBT) called exposure and response/ritual prevention (ERP). If you are interested in treatment, please contact your primary care doctor.


This study involves a single online questionnaire which should take a little less than half an hour to complete. You will be asked questions about your medical and psychiatric history, as well as your experiences using marijuana/cannabinoids.

Risks and Inconveniences

1.       The main risk of the questionnaire is that it can be boring and can ask you about difficult or personal topics. If you find the questions uncomfortable, you can stop your participation in the study at any time.

2.       Any time information is transmitted over the internet, there is a risk that it may be released to someone other than the person or group that was meant to receive it. For this reason, we will not be asking you information about your personal identity such as your name, date of birth, address, or I.P. address.


This study was not designed for your benefit. Your participation in this study may help us understand more about the relationship between OCD and marijuana/cannabinoid use.

All records will be kept confidential to the extent permitted by law. Your responses and email address (if you choose to provide it) will be stored electronically in secure, password-protected systems at the New York State Psychiatric Institute. Your name and other personal identifying information will not be collected. Records will only be available to research staff, and Federal, State, and Institutional regulatory personnel who may review the records as part of routine audits.

Study Compensation

At the end of the study, all participants will have the chance to be entered into a raffle to receive a $100 Amazon gift card.

In Case of Injury

Federal regulations require that we inform you about our institution's policy with regard to compensation and payment for treatment of research-related injuries. If you believe that you have sustained an injury as a result of participating in a research study, you may contact the Principal Investigator at (646) 774-8118 so that you can review the matter and identify the medical resources that may be available to you.


Please feel free to contact the Principal Investigator, Dr. Kayser, at (646) 774-8118 or if you have any additional questions. Take as long as you need to decide whether or not to participate in the study. If you have any questions about your rights as a research participant, want to provide feedback, or have a complaint, you may call the NYSPI Institutional Review Board (IRB - a committee that protects the rights of human subjects in research studies). You may call the IRB Office at (646) 774-7155 during regular office hours.
