Behind an imposing barbed-wired fence on a busy commercial stretch of San Pablo Avenue, this 2,500-square-foot cannabis mecca offers patients dozens of pot strands, ranging in price from the really cheap ($10/eighth) to the really expensive ($60/eighth). Make a purchase after consulting the knowledgeable and friendly white-lab-coated staff, then light up using one of the vaporizers or glass pieces available in the smoking lounge. Brownies, cookies, beverages, extracts, concentrates, and seeds round out the medication menu, while free massage, acupuncture, counseling, therapeutic, and educational services are also available on-site. If that's not reason enough to visit, Berkeley Patient Group is open eleven hours a day, seven days a week, and has rewards cards that give customers 5 percent back on every purchase. It's obviously enough to impress at least one stoner demigod; B-Real of the rap group Cypress Hill makes the occasional visit. The selection, services, and celebrity clientele can create a crowded dispensary and long lines for help, but have no fear: the staff is known to pass joints down the cue, letting patients medicate while they wait.
