ATLANTA (WXIA) - The Georgia Bureau of Investigation is sounding the alarm after three separate cases of drugs laced with deadly elephant tranquilizers were discovered in the past week.

Officials believe the drug is responsible for hundreds of overdoses in the Midwest in just the last month.  Now investigators believe the synthetic opioid carfentanil has made its way into illegal drugs in metro Atlanta.

The drug was found in three separate drug seizures of suspected heroin and is believed to be 100 times stronger than fentanyl and toxic in even small doses.

Given its use in large animals, it's so powerful that the overdose reversal drug Narcan may only be effective after multiple doses.

Adding to concerns is the fact that the drug can be absorbed through skin or inhaled forcing lab scientists to take special precautions around the deadly drug when identifying it.

And with drug making its way onto Georgia's streets, officials with the GBI said their concern is with officers who may come into contact with the substance on the job.  The officers are being warned to take extreme precaution when handling any opioid. 

The agency also warns the public to be aware of the dangers of handling or consuming the drug.
