They are also given preoperatively to relieve pain and anxiety. Common side effects include constipation, nausea, and allergic reactions. In large doses narcotics can be highly dangerous, causing stupor, coma, convulsions, or death. All narcotics are addictive; several morphine derivatives as well as chemically dissimilar narcotics that have been developed for medical use have fewer side effects and are less addictive than morphine, but they are also generally less potent.

Attempts at Control There are strict controls on narcotic prescription and administration in the United States. Nevertheless, addiction to narcotics, especially heroin, which has no legal use, continues to be a serious problem. There have been nationally and internationally based attempts to control the production of narcotics and to limit their export and import to medical use only. Large quantities are nonetheless grown in SW Asia (e.g., Afghanistan, Iran, and Pakistan), in SE Asia (the "Golden Triangle" region of Myanmar and Thailand; cultivation in Laos was largely eradicated in 2005), Lebanon, Colombia, Mexico, and Guatemala, and a large illicit traffic in these substances continues. Bibliography See publications of the Drugs & Crime Data Center and Clearinghouse, the Bureau of Justice Statistics Clearinghouse, and the National Clearinghouse for Alcohol and Drug Information. Narcotic a substance of plant or synthetic origin whose abuse leads to narcomania. In Soviet medicine the term “narcotic” is also applied to substances used for anesthesia. In addition to narcotic plants and their derivatives (the opiates; Cannabis indica and its derivatives, hashish and marijuana; Erythroxylon coca and its alkaloid, cocaine; cola, betel, and maté leaves), narcotics also include alcohol, synthetic morphine analogs, and psychotomimetics. Narcomania may result from the abuse of barbiturates, central nervous system stimulants (am phetamines and others), and other drugs that act on the nervous system. V. V. PARIN Soviet criminal law provides punishment for the making and supplying of narcotics and other potent, toxic substances. For example, according to Article 224 of the Criminal Code of the RSFSR, the making and supplying of narcotics may be punished by imprisonment of up to ten years, with or without confiscation of property. Theft of narcotics is punishable by imprisonment of up to five years, with or without confiscation of property. Criminal responsibility is also specified for planting opium poppy, Indian hemp, and southern Manchurian or southern Chu hemp without appropriate permits. Penalties exist for violating laws concerning the storage, distribution, registration, transport, and sending of narcotics, as well as for involving minors in the use of narcotics. Several international agreements deal with efforts to control the spread of narcotics. At the International Conventions of 1912, 1925, 1931, 1936, and 1945, special control was placed on the manufacture and distribution of narcotics and on the smuggling of opium, morphine, and cocaine. The 1948 Protocol placed the newest narcotics under international regulation. The International Narcotics Control Board and the United Nations Commission on Narcotic Drugs exercise general supervision over the international traffic, production, and distribution of narcotics. The USSR participates in most of these conventions for the control of narcotics. narcotic[när′käd·ik] (pharmacology) A drug which in therapeutic doses diminishes awareness of sensory impulses, especially pain, by the brain; in large doses, it causes stupor, coma, or convulsions. narcotic any of a group of drugs, such as heroin, morphine, and pethidine, that produce numbness and stupor.
