This memorandum argues that the DEA's practice of obtaining Oregon patients' prescription records from the state's Prescription Drug Monitoring Program (PDMP) without a warrant violates the Fourth Amendment. It asserts that individuals have a reasonable expectation of privacy in their prescription records, as these records can reveal sensitive health information. The memorandum maintains that both case law and state statutes recognize privacy interests in medical information. It concludes that the DEA must obtain a judicial warrant supported by probable cause before accessing individuals' prescription records from the PDMP.
