According to a study published by The Journal of Trauma and Acute Care Surgery, trauma patients who tested positive for cannabis upon admission to the intensive care unit were less likely to die during hospitalization than those without any in their system.

Researchers from the University of Arizona analyzed the in-hospital mortality rates of adults admitted into the ICU over a five year period, of which 2,6678 were matched (1,339 tested positive for cannabis, 1,339 tested negative).

They concluded patients with a positive cannabis screen had a lower mortality rate (5.3 percent versus 8.9 percent) compared to patients with negative screenings.

Prior studies had reported greater survival rates among cannabis-positive patients hospitalized for brain trauma and heart attacks as compared to control groups.
