The United States Drug Enforcement Administration (DEA) organizes drugs, substances, and chemicals used to make drugs into five separate categories, or “schedules.” These five schedules are defined by the drug’s “acceptable medical use and the drug’s abuse or dependency potential,” according to the DEA website. They are organized in descending order from highest potential for abuse to least potential for abuse.
For example, Schedule 1 drugs (shown at the top of the pyramid in the infographic) have a high abuse potential and can possibly create severe physical or psychological dependence. Schedule 5 drugs, in comparison, have limited quantities of certain narcotics, a low risk of dependence, and can be used safely for medical purposes.
To understand the differences between each schedule and types of drugs that belong in each category, read on.
Schedule 1
Schedule 1 drugs have no currently accepted medical use in the United States, a high potential for abuse, and a lack of acceptable safe use under medical supervision.
Examples of Schedule 1 drugs include:
- Heroin
- Lysergic acid diethylamide, or LSD
- Marijuana*
- Peyote
- Methaqualone
- Methylenedioxymethamphetamine, or ecstasy
In 2012, Colorado Amendment 64 legalized the production, sale, and use of adult recreational marijuana. While it is legal for adults to purchase, use, or possess marijuana in Colorado, there are some restrictions.
Schedule 2
Schedule 2 drugs, substances, or chemicals have a high potential for abuse. Use may possibly lead to severe psychological or physical dependence. They are also considered “dangerous” according to the DEA.
Examples of Schedule 2 drugs include:
- Cocaine
- Morphine
- Codeine
- Hydromorphone
- Opium
- Combination products with less than 15 milligrams of hydrocodone per dosage unit (Vicodin®)
- Meperidine (Demerol®)
- Fentanyl (Sublimaze®, Duragesic®)
- Amphetamine (Adderall®)
- Methylphenidate (Ritalin®)
- Methadone (Dolophine®)
- Oxycodone (Percocet®)
- Methamphetamine (Desoxyn®)
Schedule 3
Schedule 3 drugs have a moderate to low potential for abuse and psychological or physical dependence. The abuse potential is less than Schedule 1 and Schedule 2 drugs, but more than Schedule 4.
Examples of Schedule 3 drugs include:
- Products containing less than 90 milligrams of codeine per dosage (Tylenol® with codeine)
- Buprenorphine (Suboxone®)
- Ketamine
- Anabolic steroids
- Testosterone
Drugs in Schedule 2 and Schedule 3 are often used to treat pain or induce sedation.
Schedule 4
Schedule 4 drugs have a low potential for abuse and a low risk of dependence.
Examples of Schedule 4 drugs include:
- Alprazolam (Xanax®)
- Carisoprodol (Soma®)
- Clonazepam (Klonopin®)
- Clorazepate (Tranxene®)
- Diazepam (Valium®)
- Lorazepam (Ativan®)
- Midazolam (Versed®)
- Temazepam (Restoril®)
- Triazolam (Halcion®)
Some Schedule 4 drugs are used to treat anxiety disorders, panic disorders, or insomnia.
Schedule 5
Schedule 5 drugs, substances, or chemicals have the lowest potential for abuse of the five, and consist primarily of preparations containing limited quantities of certain narcotics.
Examples of Schedule 5 drugs include:
- Cough preparations containing less than 200 milligrams of codeine per 100 milliliters or per 100 grams (Robitussin AC®, Phenergan with Codeine®)
- Ezogabine
- Lomotil
- Motofen
- Lyrica
- Parapectolin
Schedule 5 drugs are generally used for analgesic, antitussive, or antidiarrheal purposes.
Frequently Asked Questions About Federal Drug Schedules
Federal drug schedules are often discussed in news reports, criminal cases, and drug policy debates, but many people are unsure what these classifications actually mean. Understanding how controlled substances are categorized can provide helpful context if you are facing drug-related allegations in Colorado. The answers below address common questions about federal drug schedules and their relationship to criminal drug charges.
What are federal drug schedules?
Federal drug schedules are categories used to classify controlled substances based on factors such as accepted medical use, potential for misuse, and the risk of dependence. Substances are placed into one of five schedules, ranging from Schedule I to Schedule V. The classification of a substance can affect how drug-related offenses are investigated and prosecuted.
What is the difference between Schedule I and Schedule V drugs?
Schedule I substances are considered to have a high potential for misuse and no currently accepted medical use under federal law. Schedule V substances are generally considered to have a lower potential for misuse and may have accepted medical uses. The schedule assigned to a substance reflects how lawmakers and regulators classify the drug under existing laws.
Does the drug schedule determine whether I will be charged with a crime?
Not by itself. Prosecutors also consider factors such as the type of substance, the amount involved, alleged possession, and whether there are claims of manufacturing or distribution. While the schedule can influence the severity of a case, the specific facts and evidence remain critical to how charges are handled.
Are federal drug schedules the same as Colorado drug schedules?
Not always. Colorado has its own laws governing controlled substances, and classifications may differ from federal schedules in certain situations. When someone faces drug charges in Colorado, state law often plays the most direct role in determining how the case proceeds. Understanding both systems can be important when evaluating a drug-related allegation.
Can prescription medications be classified as controlled substances?
Yes. Many prescription medications are classified as controlled substances and placed within various schedules. Possessing or using these medications without a valid prescription can potentially lead to criminal charges. The type of medication and circumstances involved may affect how a case is prosecuted.
What types of charges can result from controlled substance allegations?
Drug-related allegations can lead to several different types of charges, including:
- Possession Charges: Allegations involving possession of a controlled substance.
- Distribution Charges: Claims involving the sale, transfer, or delivery of drugs.
- Manufacturing Charges: Allegations related to producing or creating controlled substances.
- Possession With Intent to Distribute: Claims that a person intended to sell or distribute drugs rather than possess them for personal use.
The specific charge depends on the facts of the case and the evidence available to prosecutors.
How do prosecutors prove drug-related charges?
Prosecutors may rely on several forms of evidence, including laboratory testing, law enforcement reports, witness statements, physical evidence recovered during a search, and electronic communications. The reliability and admissibility of this evidence can often become important issues during a criminal case.
Can evidence be challenged in a drug case?
Yes. Drug cases frequently involve questions about searches, seizures, laboratory testing, and the handling of evidence. Defense attorneys may challenge whether law enforcement followed constitutional requirements or whether evidence is reliable enough to be used in court. Every case requires a careful review of the facts and circumstances involved.
What are the long-term consequences of a drug conviction?
A drug conviction can affect more than just the immediate penalties imposed by the court. Individuals may face challenges related to employment opportunities, housing applications, educational programs, and professional licensing. Understanding these potential consequences is an important part of evaluating any criminal case.
