Hallucinogens are classified under Schedule I of controlled substances, indicating that they have a high potential for abuse, have no currently accepted medical use in the United States, and lack accepted safety for use under medical supervision. Therefore, stating that hallucinogens are Schedule III substances is incorrect. Schedule III substances are defined as having a potential for abuse less than substances in Schedules I and II, have a currently accepted medical use in treatment in the United States, and abuse of the drug or other substance may lead to moderate or low physical dependence or high psychological dependence, which does not apply to hallucinogens.
