Map of the World of Heroin
The 'Golden Crescent' is the name given to
Asia's principal area of illicit
opium production, located at the crossroads of
Central,
South, and
Western Asia. This space overlaps three nations,
Afghanistan,
Iran, and
Pakistan, whose mountainous peripheries define the crescent.

United Nations Office on Drugs and Crime (UNODC)
heroin production estimates for the past 10 years show significant changes in the primary source areas. Heroin production in
Southeast Asia declined dramatically, while heroin production in
Southwest Asia expanded.
[ Interpol: Drugs Sub-Directorate: Heroin ] In 1991, Afghanistan became the world's primary opium producer, with a yield of 1,782
metric tons (U.S. State Department estimates), surpassing
Myanmar, formerly the world leader in opium production. The decrease in heroin production from Myanmar is the result of several years of unfavorable growing conditions and new government policies of forced eradication.
[ Afghan heroin production increased during the same time frame, with a notable decrease in 2001 allegedly as a result of the Taliban's fatwa against heroin production.][ Afghanistan now produces over 90% of the world's opium.]
History

Black tar opium seized in Afghanistan, spring 2005
The Golden Crescent has a much longer history of opium production than does Southeast Asia's Golden Triangle, even though the Golden Crescent emerged as a modern-day opium-producing entity only in the 1970s, after the Golden Triangle did so in the 1950s.
Markets
Although the Golden Triangle heroin dominates the Asian illegal drug markets, the Golden Crescent is increasingly becoming a source of illicit drugs trafficked into western China, particularly Xinjiang Province.
