Marijuana Use Associated With Decreased Mortality

Boston, MA: A history of marijuana use is associated with decreased in-hospital mortality among patients undergoing certain orthopedic surgeries, according to data published in the journal Substance Abuse.

Investigators from Tufts University in Boston and the University of Alabama at Birmingham assessed the relationship between marijuana use and in-hospital mortality in a cohort of 9.5 million patients who underwent five common orthopedic procedures: total hip arthroplasty (THA), total knee arthroplasty (TKA), total shoulder arthroplasty (TSA), spinal fusion, and traumatic femur fracture fixation.

"In this study, marijuana use was associated with decreased mortality in patients undergoing THA, TKA, TSA and traumatic femur fixation," researchers concluded. "Given the statistically significant associations between marijuana use and in-hospital outcomes in the orthopedic surgical population, more research is needed to elucidate the potential ramifications of these findings.

Other studies have previously reported that prior cannabis use is associated with decreased in-hospital mortality among trauma patients, heart attack patients, and those requiring surgery for traumatic brain injuries.
