    Prescription Monitoring Program: Controlled Substance Prescriptions by Drug Schedule

    Metadata Updated: March 1, 2026

    This dataset shows the number of prescriptions for each drug schedule category. This only includes dispensations to CT residents reported to the CT Prescription Monitoring & Reporting System (CPMRS).

    Controlled substances are classified into 5 drug schedules which are determined by the U.S. Drug Enforcement Administration (DEA) and the CT Drug Control Division. The classification is based on a drug’s medical use and potential for misuse and dependency.

    Please note that in mid-2022, NDC numbers for medical marijuana changed causing the majority of these dispensations to not be categorized as schedule II drugs during that time. Although medical marijuana is a schedule II drug in CT, these dispensations will be reported out separately beginning in 2023.
