Abstract

Tobacco use is associated with increased post-operative complications and is often underreported by patients. Recent literature also suggests that cannabis use may be correlated with post-operative complications. The prevalence of tobacco has been reported as disproportionately high in the veteran population and little is known about the population's cannabis use. Traditional biochemical testing methods, including serum and urine cotinine assays, do not differentiate active smoking from nicotine replacement therapy (NRT), and total joint arthroplasty patients are not regularly screened for the use of cannabis. This study intends to determine the prevalence of cigarette smoking, nicotine replacement therapy (NRT), and cannabis use in the population and evaluate the effectiveness of a novel point-of-care carbon monoxide (CO) breath test to verify smoking status.
