Oregon and Maine seemed to offer prudent models for the legalization of medical marijuana, because they envisioned that patients would grow their own cannabis or get it from a trusted source, rather than allow storefronts to open. In many of the states that followed this model, people can legally use marijuana but they can't legally buy it. Instead, they compensate growers for their services, or their labor, a legal distinction that keeps them from running afoul of the law. - Associated Press - September 19, 2010
