Uniform State Narcotic Act

The National Conference of Commissioners on Uniform State Laws developed the Uniform State Narcotic Drug Act in 1934 due to the lack of restrictions in the Harrison Act of 1914. The act was a revenue-producing act and, while it provided penalties for violations, it did not give authority to the states to exercise police power regarding either seizure of drugs used in illicit trade or punishment of those responsible.

Harry J. Anslinger, a member of the Federal Bureau of Narcotics, campaigned and lobbied for passage of the Uniform State Narcotic Act and the Hearst newspaper media chain was an effective ally in his campaign for passage. The draft of the act was submitted to the American Bar Association at its meeting in Washington in 1932, and it was officially approved by that body and sent to various states the following year. The purpose of the act was to make the law uniform in various states with respect to controlling the sale and use of narcotic drugs. The Commissioners on Uniform State Laws intended to effectively safeguard and regulate narcotic drugs throughout all of the states.

Initially, only nine states adopted the uniform state statute. President Roosevelt supported adoption of the Act in many more states in a message on Columbia radio network in March 1935. Anslinger launched a nationwide media campaign declaring that marijuana causes temporary insanity. The advertisements featured young people smoking marijuana and then behaving recklessly, committing crimes, killing themselves and others, or dying from marijuana use. The propaganda campaign was a success and all states signed on.

Prior to 1890, laws concerning opiates were strictly imposed on a local city or state-by-state basis. One of the first was in San Francisco in 1875, where it became illegal to smoke opium outside of opium dens. It did not ban the sale, import or use otherwise. In the next 25 years, different states enacted opium laws ranging from outlawing opium dens altogether to making possession of opium, morphine and heroin without a physician's prescription illegal.
