Which act placed a tax on opium and cocaine products and included registration requirements?

The Harrison Act is significant because it marked a pivotal moment in U.S. drug policy by imposing a tax on opium and cocaine products and establishing registration requirements for anyone involved in the manufacturing, distribution, or dispensing of these substances. This act was enacted in 1914 as part of an effort to regulate the use of narcotics and to combat widespread addiction issues.

By requiring individuals and entities to register and pay tax, the Harrison Act aimed to control the availability of these drugs and reduce misuse. It was one of the first forms of federal drug regulation, moving away from the largely unregulated environment that preceded it. This act laid the groundwork for subsequent and more stringent drug laws.

In contrast, the other options address different aspects of drug regulation and safety standards. The Pure Food and Drug Act focused on mislabeled or adulterated food and drugs, the Controlled Substances Act categorizes drugs into schedules based on their abuse potential, and the Alcohol Tax Act pertains specifically to the taxation of alcoholic beverages. Each of these serves a distinct purpose that does not specifically align with imposing a tax and registration for opium and cocaine products like the Harrison Act does.
