A marijuana sharing club is expected to open today in Bend.   Even one of the operators says it's sure to create a stir. Chris Smith plans to open Central Oregon Alternative Therapy today. He talked to the Bend City Council last week: “There is going to be an interesting subject broached here in Bend.  I am opening a business named “Coat.” It's an acronym. It stands for Central Oregon Alternative Therapy.” It's a marijuana sharing club where people using marijuana for medicinal use can share it in a controlled environment with each other.   At least one nearby business has already complained to the City.   Smith expects more and says he welcomes questions from the City or others.  COAT will be located on NE Division Street. COAT's website says they will be open today for paperwork only for prospective patients to submit applications. City Council members say there is nothing they can do right now as long as the club's follow the law, but will continue to monitor the situation.
