Note 1: Due to improved procedures implemented in 1994, these estimates are not comparable with those presented in NHSDA Main Findings prior to 1994.
Note 2: Entries are the average (mean) ages of first use of the drugs among those who have used the drug.
Note 3: The mean age should not be used to compare birth cohorts (i.e., groups of individuals born in different historical periods, such as age groups 12 to 17, 18 to 25, and others in this table) because data on the distribution of initiation ages are censored (i.e., unavailable beyond a specified age) for recent cohorts, and the age of censoring depends on the cohort. Thus, comparisons of the mean age across cohorts are biased.
