The Denver coroner says an exchange student from Wyoming fell to his death after eating a marijuana cookie.

Nineteen-year-old Levy Thamba died after falling from the balcony of a Denver hotel on March 11. An autopsy report released Wednesday says he died from the fall but also lists "marijuana intoxication" as a contributing factor in his death.

Officials at Northwest College in Powell, Wyo. say Thamba, a native of the Republic of Congo, started taking classes there as an exchange student in January.

His death is the first publicized fatality since recreational marijuana sales became legal in Colorado in January. Police have not released the findings of their investigation.
