Of the following schedule of drugs, which one deals with drugs that have no accepted medical use in the United States?

Schedule I drugs are classified as substances that have no accepted medical use in the United States and have a high potential for abuse. This classification includes drugs that are considered the most dangerous, such as heroin and lysergic acid diethylamide (LSD). The lack of accepted medical use means that these substances cannot be prescribed by healthcare professionals for any medical conditions, and they are strictly regulated under federal law. The classification underscores the significant risks associated with these drugs, both in terms of addiction and adverse health effects. In contrast, Schedule II, Schedule III, and Schedule IV drugs, while also regulated, do have accepted medical uses and varying levels of potential for abuse.
