What schedule is methaqualone classified under?

Methaqualone is classified as a Schedule I substance under the Controlled Substances Act. This classification indicates that methaqualone is considered to have a high potential for abuse, has no accepted medical use in treatment in the United States, and lacks accepted safety for use under medical supervision. Thus, it is illegal to manufacture, distribute, or possess methaqualone in the U.S. for any purpose. The Schedule I designation highlights the risks and concerns associated with the substance, which historically was known for its misuse, leading to severe legal restrictions.

Other schedules such as II, III, and IV categorize substances based on their accepted medical uses, potential for abuse, and safety profiles. However, methaqualone's classification in Schedule I reflects its status as a drug that poses significant risks without any medical justification for its use.
