GREENVILLE, PITT COUNTY -

Police have arrested a suspect and seized almost 1,000 bags of heroin laced with a powerful painkiller-- one that is 100 times more potent than morphine.

According to the Greenville Police Department, 36-year-old Jason Deshon Blount, of Greenville, was arrested after officers saw what they believed to be a drug transaction. Blount is facing numerous trafficking heroin charges and was being held in the Pitt County Detention Center under a $1.5 million secured bond.

Police said the Greenville Regional Drug Task Force concluded a two-month investigation on May 28 and seized 990 bags of heroin with an estimated street value of $19,800.

On June, 26, Greenville Police received lab results from the Pitt County Sheriff's Office, which showed that the heroin were laced with large amounts fentanyl, one of the strongest painkiller used today, police said.  It is 100 times more potent than morphine.

The heroin that were seized were in a white glassine bag with a red stamp that said "Master Mind" on the bag, investigators said.

According to Greenville Police, many cities in the northern part of the U.S. have seen a recent increase in heroin being laced with fentanyl, which has resulted in many overdoses and deaths.

Greenville Police held a news conference Friday to warn people about the drugs. The police brought in their medical expert, Dr. Raj Patel to explain more about the dangers.

"The effects of the fentanyl are far more deadly than the heroin itself," he said. "Of course they're both deadly but fentanyl causes severe respiratory depression depending on the dose."

Overdoses can slow breathing, stop the heart leading to cardiac arrest, and cause death, all in under 15 minutes, according to Dr. Patel.

Greenville Police is encouraging residents to contact local law enforcement or Crime Stoppers if they have information on the sale of the narcotic.
