An Indiana man found out that advertising doesn't always pay off – when cops busted his synthetic marijuana operation after following a hand-scrawled sign reading "Drugs This Way."

Jeremiah Scales was taken into custody after officers saw the sign, which pointed down an alley to his girlfriend's house, and staged a buy-and-bust sting that netted a sizeable amount of Spice. One neighbor said she was not surprised by the arrest, and noted there were "lots of strange people coming and going at all sorts of hours ..."

Scales is being held on drug and drug paraphernalia charges. (WTHR)
