Some addicts abuse opioids prescribed for pets. To prevent owners from taking opioids prescribed for their pets, some states now require veterinarians to check pet owners' prescription histories-and to report suspicious conduct. Maine, which saw opioid overdose deaths jump 40% from 2015 to 2016, enacted legislation directing medical professionals, including veterinarians, to check the state prescription drug monitoring program (PDMP) database before prescribing opioids or benzodiazepines. Alaska, Colorado, Connecticut, Oklahoma, and Virginia have also adopted laws or regulations enlisting veterinarians in the battle against human drug abuse. Not all states, however, agree with this approach. Most states prohibit veterinarians from accessing pet owners' prescription histories (some, like California, permit but do not require it), and most do not require veterinarians to report dispensing information to state PDMPs. Further, New Hampshire removed veterinarians from its mandate that medical practitioners check the PDMP database when veterinarians asserted that their duties did not include monitoring pet owners.
