Withdrawal from methamphetamine can produce effects such as craving, exhaustion, depression, mental confusion, restlessness and insomnia, deep or disturbed sleep sometimes lasting up to 48 hours, extreme hunger, psychotic reaction, and anxiety reactions. In general, most heroin comes from opium poppy farms in SW Asia (the “Golden Crescent,” primarily Afghanistan and Pakistan), SE Asia (the “Golden Triangle,” primarily in Myanmar), and Latin American (primarily Colombia). Heroin trafficking is heavy worldwide. According to U.N. sponsored survey, as of 2004, Afghanistan accounted for production of 87 percent of the world's heroin. As with abusers of any addictive drug, heroin abusers gradually spend more and more time and energy obtaining and using the drug. Once they are addicted, the heroin abusers' primary purpose in life becomes seeking and using drugs. The drugs literally change their brains and their behavior. On the psychological level, the study cites a number of research reports indicating many heroin addicts also suffer from psychiatric disorders, including depression, antisocial personality disorder and post-traumatic stress disorder. |
