The scene in Seattle is not what it seems at first glance. The market is only possible because, officially speaking, the stallholders and their customers are not potheads, but ''patients’’ certified under local laws to use medical marijuana. To enter, everyone must show their ''green card’’ authorisations and sign a declaration promising not to resell on the street. Officially, the market is not a market, but a “meeting point” for licensed marijuana growing collectives, and an “access point” for the patients to get their “medicine” in return for a “donation”. A heavily air-conditioned room is available for patients to “medicate” themselves for conditions that range from terminal cancer to a mildly arthritic neck.
