With Kaiser at least, if a doctor sends an Rx to the pharmacy the pharmacy can likely see the history. If the doctor sends a 90 day Rx and the last fill date was around 90 days prior, it's plain from that data the abuse is unlikely. They can also easily ping the doctor to verify the Rx and after so many Rx'es would flat the Rx as ok for 90 day supplies. But that's just me spitballing. Some random pharmacy can't see the fulfillment history from other pharmacies. They only way they could see abuse would be after the fact. They don't want to set themselves up for a lawsuit or criminal investigation so they just limit their Rx amounts.
