The short answer
The available research does not establish that cannabis causes GERD or relieves reflux. One large inpatient database analysis found different associations across esophagitis, stricture and cancer outcomes; its cross-sectional design cannot determine cause and effect. A systematic review also describes heterogeneous, limited GI evidence. These findings are not a personal treatment guide.
A useful way to discuss symptoms
Record when reflux occurs, meals, cannabis product and route, other substances, and medicines, then discuss persistent symptoms with a qualified clinician. Do not start, stop or substitute cannabis for prescribed GERD treatment because of observational findings. For interactions, see our medication overview.
