| − | '''Opium''' is a narcotic and a derivative of poppies. It is exported frequently from [[Afghanistan]] and [[Myanmar]]. Opium is a Schedule II narcotic as determined by the Drug Enforcement Administration (DEA). Opium can cause euphoria, followed by a sense of well-being and a calm drowsiness or sedation. Breathing slows, potentially to the point of unconsciousness and death with large doses. Other effects can include nausea, confusion and constipation. Use of opium with other substances that depress the central nervous system, such as alcohol, antihistamines, barbiturates, benzodiazepines, or general anaesthetics, increases the risk of life-threatening respiratory depression.
