*Low precision; no estimate reported.
NOTE: Percentages are calculated using a weighted ratio estimate where the numerator is the weighted sum of all lifetime users within each age group for a specific year and the denominator is the weighted sum of all persons within each age group for the same year. Lifetime drug use status and age group, for each specified year, were determined using the age, date of first use, and interview date for each respondent. See Section B.5 of Appendix B of the Results from the 2002 National Survey on Drug Use and Health: National Findings.
