"I recently moved to California and got my medical marijuana card here, but I don’t yet have a CA license; I still have my Indiana driver’s license."
This really depends on the dispensary. If you have a California recommendation and a government-issued ID there is nothing in the state law that prevents you from purchasing cannabis. Still, many dispensaries don’t realize this and only allow those with California licenses to purchase. Call ahead to dispensaries in your area and ask about their particular policies. I’ve had good luck finding places that are willing to let out of state patients shop there, but sometimes it can take a little looking around.
