An enterprising New Jersey man raked in up to $20,000 a day running illegal marijuana vending machines — with at least 80 locations across the state, prosecutors said. Ben Gross, a 40-year-old Toms River resident, was arrested Friday after investigators identified him as the owner of the Barbwire vending machine company. Cops in Ocean and Monmouth counties spent more than two years tracing the operation, officials said. Prosecutors said Gross made between $17,000 and $20,000 per day from the machines.
