What is the mnemonic to help remember the schedule I controlled substances?

• A. H - Heroin, L - Lysergic acid diethylamide, M - Marijuana, M - Methaqualone
• B. H - Hallucinogens, L - LSD, M - Methamphetamine, M - Marijuana
• C. H - Heavy metals, L - Limiting substances, M - Morphine, M - Methaqualone
• D. H - Heroin, L - Legal drugs, M - Medical marijuana, M - Methamphetamine

Answer: (A)

The correct mnemonic to remember the schedule I controlled substances is the one that lists heroin, lysergic acid diethylamide (LSD), marijuana, and methaqualone. This selection is accurate because all these substances are classified as schedule I drugs under the Controlled Substances Act. Schedule I substances are defined as having high potential for abuse, no accepted medical use in the United States, and a lack of accepted safety for use under medical supervision.

Heroin is an opioid that is not legally prescribed and has no accepted medical use. LSD is a hallucinogenic drug with similar legal status. Marijuana, despite some states legalizing it for medical or recreational use, remains classified as a schedule I drug at the federal level. Methaqualone was used as a sedative but is also classified as schedule I due to its high potential for abuse.

Other options incorrectly list substances or classifications that do not fit the criteria for schedule I drugs. For example, some choices may include drugs that are recognized for medical use or are classified under different schedules, thus failing to adhere to the definition necessary to be remembered with a schedule I mnemonic.
