A traffic stop leads to a drug investigation. Wednesday night, Lafayette Metro Narcotics Agents pulled over a vehicle on I-10. Two men were inside. When detectives searched it, they found a large amount of suspected bath salt inside. Then, one of the men admitted there was more of the drugs in his house. There, authorities found more suspected Bath Salt, packing material, labels and a printer used to make them. It's believed the man was lacing the synthetic marijuana with the Bath Salt, packaging the substance and selling it to local stores. The man was not arrested pending further investigation.
