PubMed and Medline were utilized in this searc. A total of twenty articles have been referenced in this project. Most of the information was obtained from studies performed in the United States, Canada, Australia and Uruguay.

Results: Articles were obtained from various countries regarding public health impacts of marijuana and cannabis use as well as increase in adverse events after legalization and decriminalization of marijuana and cannabis. Information was available regarding cardiopulmonary diseases and mental health impacts from marijuana and cannabis use.

Several countries reported an increase in motor vehicle accidents and deaths after legalization or decriminalization of marijuana. Marijuana users were noted to have an increase in negative mental health, including psychosis and suicidal behaviors, when compared to nonusers. Data demonstrates an increase in marijuana use after legalization or decriminalization.
