On a sunny day in October, Mike Arnold swings open the door to his barn storehouse outside of Eugene, Oregon, and takes a big whiff. The stench hits him immediately, a sweet and skunky wall of cool air. “Smells like money,” Arnold says in his Missouri drawl, gazing out at row after row of makeshift wood-and-mesh shelving, where 12,000 pounds of marijuana were lying out to dry.
Even as marijuana becomes increasingly mainstream, not everyone is feeling chill about legalization. Pot reeks, and pot being grown or processed at commercial scale reeks even more. Some states and municipalities have included specifications about odor control in their medical and recreational marijuana regulations.
