Which of the following is a common Schedule II drug?

Cocaine is classified as a Schedule II drug primarily because it has a recognized medical use in the United States, particularly as a local anesthetic in specific medical situations. Schedule II drugs are substances that have a high potential for abuse, which can lead to severe psychological or physical dependence, but they also have approved medical applications. This regulatory classification means that cocaine can be prescribed by healthcare professionals under strict controls.

In contrast, heroin is classified as a Schedule I substance, meaning it has no accepted medical use and a high potential for abuse. LSD, also a Schedule I drug, is known for its hallucinogenic properties and is not recognized for medical use. Marijuana has varying classifications in different contexts but is often not considered a Schedule II drug given its broader acceptance and state-level legal status, despite being classified as Schedule I at the federal level.
