Narcotics


The term narcotic derives from the Greek word for stupor.  Narcotic use is associated with a variety of unwanted effects, including drowsiness, inability to concentrate, apathy, lessened physical activity, constriction of the pupils, dilation of the subcutaneous blood vessels causing flushing of the face and neck, constipation, nausea and vomiting and, most significantly, respiratory depression.  With repeated use of narcotics, tolerance and dependence develop.  Users of narcotics, such as heroin, codeine, morphine, and opium, are susceptible to overdose that can lead to convulsions, coma and death.
