Problem #2. Little is known about heroin and cocaine use in Afghanistan. Opium was known to
the ancient Persians and has traditionally been used for recreation, pain relief, and treatment of
mental disorders. Data were gathered from 306 consecutive addicts who sought treatment an
identified addicts center from July to September in a recent year. An interview was conducted
with the subject and a close rélative. The data collected revealed that the mean (average) age of
the subject was 37.0 years; that 97.7% were male, of whom 73.9% were married and 24.2% were
single. About 36 % of the addicts reported that they had been using the substance for more than
10 years. Only 2.3% reported use of one-year or less. The Table below gives the frequency
distribution for the longest duration of abstinence. 74.3% gave a history of abstinence. Only
1.6% reported 5 years or more as the longest period of abstinence. 18.3% indicated one to three
months as the longest period of abstinence. Overall, 62.1 % relapsed before one year of
abstinence had elapsed.
