The Miami-Dade Medical Examiner found only marijuana in the body of the man who was fatally shot while chewing a homeless man's face over Memorial Day weekend.
The medical examiner's office said on Wednesday that 31-year-old Rudy Eugene's toxicology was complete.
"The department's toxicology laboratory has identified the active components of marijuana," the medical examiner said in a statement. "The laboratory has tested for but not detected any other street drugs, alcohol or prescription drugs, or any adulterants found in street drugs."
The department also ruled out common drugs found in the street drugs called bath salts, which authorities had initially speculated were the cause of the brutal attack on Ronald Poppo.
He has been recovering at Jackson Memorial Hospital's Ryder Trauma Center since the May 26 attack along the MacArthur Causeway.
Poppo was rushed to the hospital after he was attacked by Eugene, who tore off and chewed most of the 65-year-old's face, authorities said. He also suffered trauma to his brain, doctors said.
Poppo also had a couple puncture wounds in his left chest area.
