DEA drug schedules
Also known as: controlled substance schedules, csa schedules
The DEA drug schedules are five categories established by the Controlled Substances Act that rank drugs by abuse potential and accepted medical use. Schedule I has the highest abuse potential with no accepted medical use, and Schedule V has the lowest.
The Controlled Substances Act of 1970 created a tiered system administered by the Drug Enforcement Administration. Placement in a schedule reflects three factors: the drug's potential for abuse, whether it has a currently accepted medical use in the United States, and the degree of physical or psychological dependence it may cause.
Schedule I drugs have high abuse potential and no accepted medical use, so they cannot be prescribed — heroin and LSD are examples. Schedule II drugs also carry high abuse potential and can cause severe dependence, but they do have accepted medical uses; this tier includes strong opioids such as morphine, oxycodone, and fentanyl, along with stimulants like amphetamine and methylphenidate. Schedule III covers drugs with less abuse potential than Schedule II, including anabolic steroids, ketamine, and certain codeine combination products. Schedule IV includes benzodiazepines, zolpidem, and tramadol. Schedule V holds the lowest-risk controlled substances, such as antitussive preparations containing limited amounts of codeine.
The schedule determines how a prescription may be handled. Schedule II prescriptions may not be refilled and require a new prescription each time, with emergency oral orders permitted only under narrow conditions and limited quantities. Schedules III and IV may be refilled up to five times within six months of the date written. Schedule V products carry the fewest restrictions, and some may be dispensed without a prescription where state law allows. Pharmacies must also meet recordkeeping requirements, including a biennial controlled substance inventory, DEA Form 222 or its electronic equivalent for ordering Schedule II drugs, and DEA Form 106 for reporting theft or significant loss.
The PTCE tests drug schedules in two places: classification of medications, where you match drugs to their schedule, and the federal requirements domain, where you apply the refill limits, transfer rules, and recordkeeping obligations attached to each tier. The CCMA touches on controlled substance law within its coverage of healthcare regulations.
Key takeaways
- The Controlled Substances Act sorts drugs into Schedules I through V by abuse potential and accepted medical use.
- Schedule I drugs have no accepted medical use and cannot be prescribed; Schedule II drugs are prescribable but have high abuse potential.
- Schedule II prescriptions cannot be refilled, while Schedules III and IV allow up to five refills within six months.
- Controlled substance handling carries extra requirements, including biennial inventories and DEA Form 222 for Schedule II ordering.
