Study: History Of Marijuana Use Inversely Associated With In-Hospital Mortality

Greeley, CO: Hospitalized patients who test positive for cannabis are less likely than non-users to suffer from heart failure or cardiac disease, and are less likely to die from cancer, according to data published online ahead of print in the journal Cancer Medicine.

A team of researchers from the University of Northern Colorado, Colorado State University, and the University of Alabama assessed the relationship between marijuana use and health outcomes among a nationwide sample of 3.9 million hospitalized patients.

Researchers reported that marijuana-positive patients were more likely than non-users to seek hospitalization for stroke, but that they possessed lower odds of heart failure or cardiac disease, and that they possessed increased survival rates overall – especially among those patients with cancer. Authors concluded, “Odds of in-hospital mortality were significantly reduced among marijuana users compared with non-users in all hospitalized patients as well as cancer patients.”

Separate data, presented in April at the 2016 meeting of the American College of Cardiology, reported that heart attack patients with a history of cannabis use are less likely than non-users to die during hospitalization. A 2014 UCLA study similarly reported greater survival rates in marijuana-positive patients hospitalized for Traumatic Brain Injury.
