We all know that cannabis prohibition is on the way out in California, but there are still a lot of questions in the air. That’s where the Sonoma Blossom Festival, now in its second year, comes in. This all-day educational event is the best way to get information on medical cannabis and more. Early in the day, there’s advocacy training, “know your rights” role-playing exercises, a legal panel and more, before live music, collaborative painting and other entertainment takes over in the evening. This is an alcohol-free event, but food will be on hand and a medical marijuana area for patients with paperwork. The festival takes place on Sunday, Aug. 30, at the Arlene Francis Center, 99 Sixth St., Santa Rosa. 2pm to midnight. $15–$20.
