Ritalin is classified as a Schedule II controlled substance in the United States under the Controlled Substances Act, meaning it has a high potential for abuse and dependence, but is also recognized for its medical utility. The Drug Enforcement Administration (DEA) regulates its distribution tightly, requiring careful medical oversight and prescription refills. Misuse or non-medical use of Ritalin, such as for performance enhancement or recreational purposes, can lead to legal consequences, and there is an ongoing debate about the ethics and safety of its use.
