Police say the marijuana-laced cartridges recovered in last week's bust are flavored and don't produce a pungent smell.
"Honeydew Mango, Sour Diesel, Pineapple Express and Wedding Cake," said Gloucester Township Police Chief Harry Earle, listing some of the flavors of the cartridges seized.
Police are also concerned about the possibility of e-cigarettes becoming a delivery device for even harder narcotics such as cocaine and heroin.
They are urging parents in the area to talk to their kids.
