Inclusion algorithm for final study population.
Inclusion and exclusion criteria used to select the final study cohort. Individuals ≤ 18 years of age and those ≥ 70 years of age were excluded. Individuals who had used alcohol, cocaine, or methamphetamine prior to admission for acute myocardial infarction were also excluded from the study to reduce confounding co-substance influences.

Rates of adverse outcomes in patients with acute myocardial infarction reported cannabis use vs. no cannabis use.
Patients who reported marijuana use has decreased short-term risk of death, shock, and IABP placement in hospital while they had an increased risk of mechanical ventilation when compared to patients that reportedly did not use marijuana prior to admission for AMI.
