A college student from Wyoming died in Colorado after eating marijuana-infused cookies during spring break.

Levy Thamba Pongi, who is a foreign exchange student from Congo, fell from a motel balcony on March 11 and reports from his autopsy reveal that marijuana was a "significant contributing factor" in his death.

Colorado law allows purchase of marijuana and marijuana products for recreational use to individuals 21 years of age and older. Those who provide marijuana to an underage individual can be charged with a felony. Pongi was only 19.

It is believed that one of Pongi's friends, who was at least 21, purchased the cookie to share with Pongi and his friends.

Pongi's friends reported him acting strangely after eating the cookie. They said he was tearing things off walls and speaking erratically.

Pongi's three friends tried to calm him down, but he went outside and jumped off the balcony, falling four stories to his death from multiple skull fractures.

Besides Pongi, one of his friends also tried the cookie but felt sick and discontinued ingesting it, according to Michellle Weiss-Samaras, a spokesperson from the Denver medical examiner's office.

The medical examiner's office tested Pongi's body for over 250 different substances, including marijuana. They noted that bath salts and synthetic marijuana often cause strange behavior.

The only result the office found in Pongi's blood was THC, the psychoactive ingredient in marijuana.

Pongi's level of marijuana concentration in his blood was 7.2 nanograms of active THC per milliter of blood. In Colorado, someone driving with more than 5 nanograms per milliter in their blood is considered driving while impaired.

Pongi and his friends were all foreign exchange students and were traveling to Colorado, where recreational marijuana is legal, to try the drug.

"They come here for spring break to try marijuana. They were young kids," Weiss-Samaras told 7NEWS.

Dr. Scott Bentz, medical director at Presbyterian St. Luke's Medical Center in Aurora, Colo., is surprised of the way the marijuana affected Pongi.

"Marijuana typically, whether it's inhaled or eaten, does not typically affect impulse control in this way." Bentz said.

Pongi had just arrived at Northwest College in Powell, Wyo. in January. He was studying engineering, officials from Northwest College say.

This is the first known death linked to marijuana since it became legal for recreational use in the state of Colorado.
