In states with legal weed things are a bit different today. Every gram of legal weed is tracked using sophisticated surveillance networks and many dispensaries keep meticulous records of their customers’ information, including their phone number and address, even if they aren’t required to by law. Privacy groups like the Electronic Frontier Foundation are concerned this customer data may be sold to third-party data brokers or handed over to federal law enforcement officers.
Some states with legal pot, such as Oregon and Alaska, have explicitly prohibited the collection and sale of cannabis customer data. But until recently the privacy implications of legal pot have mostly gone unchecked in California, which is expected to become home to the largest marijuana industry in the United States.
