A foreign student at Korea University who smoked marijuana in the dormitories had to be rushed to the hospital when he suddenly began having convulsions. According to Korea University Hospital and local police on the 27th, 18-year-old N, an international student from Kazakhstan, was smoking something with two Russian friends in the dormitory on the 23rd. A paramedic who took N to the hospital said that “at first he was unconscious and having convulsions.” An official at the hospital said that “at first N was unconscious and convulsing, then began to laugh and attempted to leave the bed… we reported to police that he appeared to have used drugs.”

Police who arrived were told that “we thought we had smoked marijuana” but, police said, urine testing showed that “it was likely neither marijuana nor a synthetic drug… further forensic testing will determine its true nature.”
