(WHDH) -- Police in Quincy, Massachusetts say the designer drug Molly is showing up there.
After a dozen people were arrested at one club, police are now using some new technology to help identify the drug.
Using a cutting edge laser drug detection device called TruNarc, an undercover detective in Quincy is able to test drug samples on the spot.
"When we hit the scan button the laser will strike that sample in question," one detective said.
