Owner Jeff Call charges patrons a small fee to become a member of the private second-floor club, which prohibits smoking marijuana, but does permit “vaporizing,” a method that involves heating the marijuana without burning it. Last fall, Washington and Colorado became the first states to legalize marijuana use for adults over 21. (AP Photo/Ted S. Warren)
