Chart of Scheduled Drugs (I–V): A Guide for Addiction & Mental Health

At a Glance: Chart of Scheduled Drugs

What is the chart of scheduled drugs?It’s the U.S. government’s system for classifying controlled substances into five schedules based on medical use, misuse potential, and dependence risk.

What schedule is Adderall? Adderall is a Schedule II stimulant, tightly controlled due to its high misuse potential.

Is alcohol on the chart? No. Alcohol is not scheduled under the Controlled Substances Act. It is regulated separately.

What are schedule one drugs?These include substances like heroin, LSD, and MDMA, considered to have no accepted medical use and a high potential for misuse.

What are schedule two narcotics? They are powerful opioids such as oxycodone, hydromorphone, fentanyl, and methadone, listed as narcotics due to their potency and misuse risks.

Why does this matter for addiction and mental health?Scheduling affects how drugs are prescribed, researched, and accessed. Understanding it helps people see the balance between medical use, legal status, and treatment barriers.

If you work in addiction and mental health, or you’re simply trying to understand a loved one’s prescription, it helps to know how the U.S. Controlled Substances Act (CSA) classifies medicines and illicit drugs. Below you’ll find a clear chart of scheduled drugs, a concise explanation of what each schedule means, and answers to common questions such as adderall scheduling, the alcohol schedule, and what people mean by a list of narcotics (including schedule one drugs and schedule two narcotics).

What “schedules” mean under the CSA

The CSA places certain substances in five schedules based on three factors: (1) accepted medical use, (2) potential for misuse, and (3) safety/dependence risk. Schedule I is the most restricted; Schedule V is the least restricted. The DEA administers scheduling with scientific evaluations from HHS/FDA, and there’s a formal process for adding, moving, or removing substances from schedules.

Who decides, and how does it change?

DEA initiates rulemaking, requests a scientific/medical evaluation from HHS/FDA, and then issues a final rule. FDA’s scientific findings are binding on DEA, but DEA has the final scheduling authority within the statute. This is why rescheduling can take months or years and may include public hearings.

Schedule I

People sometimes Google schedule i narcotics, but “narcotic” in U.S. law typically refers to opioids and coca‑leaf derivatives. Schedule I contains both opioids (e.g., heroin) and non‑opioids (e.g., LSD, MDMA). The uniting feature is no currently accepted medical use and high misuse potential under federal law. States may treat particular drugs differently, but state laws don’t change federal scheduling.
