Weed linked to death of exchange student

An exchange student fell to his death after ingesting marijuana in Colorado - the first death linked to the drug since it was legalised in the US state according to A BBC report.
Levy Thamba, 19, plummeted from the balcony of a Denver hotel on 11 March 2014 after eating a cannabis-laced cookie. A post-mortem examination found marijuana intoxication was a factor in the Wyoming student's death.
Colorado became the first US state to legalise recreational use of the drug in January. Mr Thamba, a native of the Republic of Congo, had reportedly begun taking classes at Northwest College in Powell, Wyoming, the same month.
Currently, 20 US states as well as Washington, DC allow for the sale of medical marijuana, while Washington state is set to introduce legal sales later this year.
