What is mescaline classified as in terms of scheduling?

  1. Schedule II

  2. Schedule I

  3. Schedule III

  4. Schedule IV

The correct answer is: Schedule I

Mescaline is classified as a Schedule I substance under the Controlled Substance Act. This classification indicates that it is considered to have a high potential for abuse, no currently accepted medical use in treatment in the United States, and a lack of accepted safety for use under medical supervision. These criteria are established to regulate substances that are viewed as potentially harmful and having no legal medical application. Other schedules, such as Schedule II, Schedule III, and Schedule IV, include substances with accepted medical uses but varying levels of potential for abuse and dependency. Schedule II substances, for example, may be prescribed but are subject to stricter regulations due to their potential for addiction. Mescaline's categorization as Schedule I highlights its status as a drug that is not legally available for medical use and is strictly controlled.
