Large quantities of drugs were found inside merchandise from at least two Home Depot stores in Massachusetts, and authorities are investigating, police said Wednesday. A contractor late last week discovered two 50-pound "bricks" of marijuana wrapped in plastic bags inside a bathroom vanity he had purchased at a Home Depot store in Tewksbury, said Chief of Detectives Lt. Dennis Peterson. The estimated street value of the marijuana is around $145,000, Peterson said. Similar incidents have occurred in other parts of the state.
