The cultivation of opium in Afghanistan reached its peak in 1999, when 225,000 acres - 350 square miles - of poppies were sown. The following year the Taliban banned poppy cultivation, a move which cut production by 94 per cent. By 2001 only 30 square miles of land was in use for growing opium poppies. A year later, after American and British troops had removed the Taliban and installed the interim government, the land under cultivation leapt back to 285 square miles, with Afghanistan supplanting Burma to become the world's largest opium producer once more.

Cocaine use among men is almost twice then women. Based upon additional data sources, the office of National Drug Control Policy estimates the number of chronic cocaine users at 3.6 million.

The past five years have seen a consistent year-over-year increase in emergency room visits related to heroin of 10% - 15%.

Another one of the risks of heroin use is that all heroin users--not just those who inject the drug-- becoming addicted. Individuals who abuse heroin over time develop a tolerance for the drug, meaning that they must use increasingly larger doses to achieve the same intensity or effect they experienced when they first began using the drug. Heroin ceases to produce feelings of pleasure in users who develop tolerance; instead, these users must continue taking the drug simply to feel normal. Addicted individuals who stop using the drug may experience withdrawal symptoms, which include heroin craving, restlessness, muscle and bone pain, and vomiting.
