There is a research study interested in
1) patients with nausea/vomiting that use marijuana/cannabis or
2) people that use cannabis/marijuana and develop nausea/vomiting.
Dear Patient,
reports from patients suggest that use of cannabis/marijuana reduces symptoms like nausea and vomiting, other studies suggest that nausea and vomiting may be caused by cannabis/marijuana use.
In order to bring this to a scientific level more detailed information from patients is wanted. We are conducting a study that is assessing the use, the benefits and the side effects of cannabis/marijuana for the treatment of nausea/vomiting or the occurrence of nausea/vomiting as a side effect of cannabis/marijuana use.
This research study has been approved by the University of Calgary, Canada, Conjoint Health Research Ethics Board. You are under no obligation to complete this questionnaire. Your responses to this questionnaire will be kept strictly anonymous.
