2002 State Estimates of Substance Use

End Notes

1 In 2002, the name of the survey was changed from the National Household Survey on Drug Abuse (NHSDA).

2 For a thorough discussion of the impact of these changes, see OAS (2003a) and Appendix C of OAS (2003b).

3 RTI International is a trade name of Research Triangle Institute.

4 For details on how the average annual rate of first use of marijuana (incidence of marijuana) is calculated, refer to Section B.6 of Appendix B.

5 For details, see Volume II, Section B.4 in Appendix B, in the 2000 State report (Wright, 2002b). For a detailed discussion of the small area estimation (SAE) methodology, see Appendix E of the 2001 State report (Wright, 2003b). The methodology used in 2002 is similar to that for 2000–2001, with the exception of the variable selection procedure for modeling (for details on the variable selection procedure used, see Appendix B, Section B.3, of the present report) and the fact that the estimates for 2002 are based on only a single year's data.

6 Tables B.1 through B.4 of Appendix B in this report provide response rates for 2000–2001 and 2002.
