      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.},
