They have specific information about this on their website. Interestingly, the California Attorney General Guidelines are more strict than what is required in the state legislation; they "recomend" that records regarding all transactions be kept by all dispenceries. Now you may think these dispenceries are all about privacy, and they are to a degree. If you look at Federal marijuanna arrests, they involve either growers or shop owners and not typically patients. These places do not want to give the state government any reason to bust them and turn them over to the federal government for 100% guarenteed prosecution. So Many of these dispenceries abide strictly with all of the state laws and "suggestions/ recomendation." Be really careful here!
