MORTALITY RATES & Cannabis studies completed


There has still never been a documented overdose death due to cannabis/marijuana.

Mortality rate is a measure of the number of deaths (in general, or due to a specific cause) in a population, scaled to the size of that population, per unit of time.

The use of cannabis is associated with lower mortality risk in patients with schizophrenia and related psychotic disorders, according to a forthcoming study to be published in the Journal of Psychiatric Research.
