The document reports on substance abuse issues. It finds that substance abuse is one of the top 10 causes of death in Brooklyn, though not nationwide. In Brooklyn in 2002, nearly 90% of drug-related hospitalizations were due to heroin use, and rates were highest among black residents and in certain neighborhoods like Williamsburg. The costs of substance abuse are high both in terms of health effects, like 100,000 deaths annually from alcohol, and economic costs estimated at $276 billion in 1995. Early intervention and treatment can help reduce these impacts.
