The GBI Crime Lab has fully identified the compounds inside the counterfeit pills related to the dozens of overdoses and deaths in central Georgia.
The complete analysis confirms the pills are a mixture of two synthetic opioids -- cyclopropyl fentanyl, and U-47700.
Cyclopropyl fentanyl is chemically similar to fentanyl, but its effects on the human body are unknown since it is not intended for human or animal use.
That particular compound had not been previously seen in Georgia prior to the recent overdoses.
The release says both can be absorbed through the skin and are highly toxic.
The GBI is still investigating the source of the pills.
