Marijuana use among orthopedic patients has not been extensively studied. The purpose of this study was to investigate the prevalence of marijuana use among orthopedic surgery patients. Additionally, the authors sought to better characterize how and why their patients use marijuana. Patients presenting at 3 institutions in 2 states for orthopedic surgery were asked to complete a voluntary survey. In addition to basic demographic information, the survey contained questions regarding the frequency of, methods of, and reasons for marijuana use. Patients who had used marijuana in the past year were categorized as marijuana users. A total of 275 patients completed surveys, of whom 94 (34%) endorsed marijuana use in the past year. A majority of marijuana users (55%) endorsed using marijuana either daily or weekly. Smoking was the most common means of marijuana use (90%), followed by edible products (35%) and vaporizing (24%). Pain management (54%) and recreation (52%) were the most commonly cited reasons for using marijuana. Eighty-six percent of marijuana users indicated that they would stop using marijuana if told by their physician that marijuana use would adversely affect their surgery. Marijuana use is common among orthopedic patients. Many patients believe marijuana is beneficial for managing pain and other medical conditions, although most would be willing to stop using marijuana if told it would negatively impact their surgery. Further study into the effects of marijuana use on musculoskeletal health is warranted because marijuana use may be a risk factor easily modified to improve surgical outcomes.
