Numerical/Quantitative Data (110) Reports Descriptive

Survey on Drug Abuse (NHSDA). Several important changes to the NHSDA in 1999 and 2000 affected the estimates of drug use, as well as the estimates for dependence, abuse, and needing and receiving treatment. Following the introduction, the report is organized as follows. Chapter 2 offers estimates of the prevalence and patterns of substance dependence and abuse in the nation. Chapter 3 provides estimates of the prevalence and patterns of the receipt of treatment for problems related to substance use. Chapter 4 discusses the need for and receipt of treatment specifically for problems associated with illicit drug use. Appendix A describes the survey in more detail discussing the sample design, the methodology, and the data processing. Appendix B provides information on the statistical methods and limitations of the data. Appendix C discusses the measurement of dependence, abuse, treatment, and treatment need and describes the changes to these measures in 2000. Appendix D describes other sources of data on substance abuse, dependence, and/or treatment for a substance abuse problem. Appendix
