DEA Controlled Substance Drug Schedules - Pharmacy Law Test Prep Study Guide NAPLEX, PTCB PTCE
Summary
This video explains the Drug Enforcement Agency (DEA) controlled substance schedules, categorizing drugs based on medical use and abuse potential. It details five schedules, from Schedule I (no medical use, high abuse potential) to Schedule V (low abuse potential), providing examples for each category and clarifying their general uses, such as pain relief, anxiety, sleep, and cough suppression. The core takeaway is understanding how drugs are classified to manage their use and prevent abuse.

Introduction to DEA and Controlled Substances
The DEA enforces US controlled substance laws.
The Drug Enforcement Agency (DEA) is the federal organization responsible for enforcing the controlled substance laws within the United States.
Controlled substances are defined by the CSA of 1970.
A controlled substance is defined by the DEA as any substance listed in the schedules of the Controlled Substance Act (CSA) of 1970.
Drug schedules categorize substances by medical use and abuse potential.
Drug schedules are categories developed by the DEA to classify controlled substances. This classification is based on two main factors: the drug's acceptable medical use and its potential for abuse or dependence.
Overview of Controlled Substance Schedules
There are five DEA-defined controlled substance schedules.
There are five schedules for controlled substances, generally designated by Roman numerals. Each schedule has a different level of medical use and abuse/dependency potential.
Schedule I: No medical use, high abuse potential.
Schedule I drugs have no currently accepted medical use in the United States and a lack of accepted safety for use under medical supervision. They have a high potential for abuse.
Schedule II: High abuse potential, risk of dependence.
Schedule II drugs have a high potential for abuse and dependence.
Schedule III: Moderate to low dependence, less abuse.
Schedule III drugs have a moderate to low potential for physical dependence and high psychological dependence.
Schedule IV: Low dependence and less abuse potential.
Schedule IV drugs have a low potential for abuse relative to Schedule III drugs and are generally associated with low dependence and less abuse potential.
Schedule V: Lowest potential for abuse.
Schedule V drugs have the lowest potential for abuse relative to Schedule IV drugs.
Detailed Breakdown of Each Schedule
Schedule I examples include illegal drugs like heroin and LSD.
Schedule I drugs, such as heroin, LSD, and ecstasy, are considered illegal in the US and have no accepted medical use or safety under medical supervision, despite a high potential for abuse.
Schedule II drugs have accepted medical use but high abuse potential.
Schedule II drugs, including narcotics like methadone, hydromorphone (Dilaudid), oxycodone (OxyContin), fentanyl, and morphine, and stimulants like methylphenidate (Ritalin), amphetamine (Adderall), methamphetamine, and cocaine (used as an anesthetic), have currently accepted medical uses but carry a high risk of severe psychological or physical dependence.
Schedule III drugs include codeine combinations and anabolic steroids.
Schedule III drugs have less abuse potential than Schedule I or II. Examples include products with less than 90 mg of codeine per dosage unit (like Tylenol with Codeine), anabolic steroids such as testosterone, and ketamine. Abuse can lead to moderate to low physical dependence or high psychological dependence.
Schedule IV drugs often used for anxiety and sleep, have low abuse potential.
Schedule IV drugs typically used for anxiety and sleep have a low potential for abuse. Examples include zolpidem (Ambien), benzodiazepines like alprazolam (Xanax), clonazepam (Klonopin), diazepam (Valium), temazepam (Restoril), and lorazepam (Ativan). Other examples include tramadol (Ultram), carisoprodol (Soma), and phentermine.
Schedule V drugs are typically cough and anti-diarrheal preparations.
Schedule V drugs have a low potential for abuse relative to Schedule IV. They mainly consist of preparations with limited quantities of certain narcotics, often used for anti-diarrheal purposes (like diphenoxylate/Imodium), pain relief (like pregabalin/Lyrica), or cough suppression (like Robitussin AC or codeine-containing syrups). These preparations contain not more than 200 mg of codeine per 100 mL or 100 g.
Key Takeaways on Drug Scheduling
Classification is based on medical use and abuse/dependence risk.
Drug schedules are categories created by the DEA to classify controlled substances. The classification hinges on two primary factors: the drug's accepted medical use and its potential for abuse or the dependence it can cause.
Schedule I has no medical use and high abuse risk.
Schedule I drugs are characterized by having no accepted medical use in the United States and a high potential for abuse.
Schedule II includes narcotics and stimulants with high abuse potential.
Schedule II drugs have a high potential for abuse and can lead to severe psychological or physical dependence. This category includes many potent narcotics and stimulants.
Schedule III offers less abuse potential with moderate/low dependence.
Schedule III drugs present a lower potential for abuse compared to Schedules I and II, with associated risks of moderate to low physical dependence or high psychological dependence. This includes certain codeine preparations and anabolic steroids.
Schedule IV drugs are typically for sleep/anxiety with low abuse risk.
Schedule IV drugs are generally considered to have low dependence and less abuse potential. They often include medications used for anxiety and sleep issues.
Schedule V drugs have the lowest abuse potential.
Schedule V drugs possess the lowest potential for abuse among the controlled substances, typically found in cough preparations or medications for diarrhea.
