Smuggling drugs by swallowing them isn’t only illegal — it’s dangerous.

Miguel Rodriguez, 51, allegedly gulped down 27 bags of heroin in order to carry them into the United States, according to police in Salem, MA. Rodriguez recently returned from a visit to the Dominican Republic, and after family members found him unresponsive, he was transferred to Salem Hospital. Hospital staff ran imaging scans and found the heroin in his stomach, one bag of which had broken open.

Hospital staff gave Rodriguez the opiate blocker Narcan, and he will be arraigned as soon as he is conscious, reported The Salem News. Doctors removed the bags, which contained a total of 163.4 grams of heroin, from Rodriguez’s stomach, intestines, and rectum during emergency surgery Tuesday. Police obtained a warrant to search the bags after a nurse called them in, concerned Rodriguez may have been a drug mule.

Police say the drugs could have a street value of more than $16,000.
