This is the 29th annual survey in this series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students are randomly assigned to complete one of six questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and drug use. There are about 1,400 variables across the questionnaires. Drugs covered by this survey include tobacco, alcohol, marijuana, hashish, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), Quaaludes (methaqualone), barbiturates (tranquilizers), cocaine, crack cocaine, GHB (gamma hydroxy butyrate), and heroin. Other items include attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime (both in and out of school).

To protect the privacy of respondents, all variables that could be used to identify individuals have been collapsed or recoded in the public use files. These modifications should not affect analytic uses of the public use files.
Variables omitted from the Western region questionnaires are noted in each codebook.
A user guide is provided with the study documentation. It contains a year-to-year cross-time question index for the MTF 12th-grade surveys that is sorted by subject area, item reference number, and questionnaire form.
Multistage area probability sample design involving three selection stages: (1) geographic areas or primary sampling units (PSUs), (2) schools (or linked groups of schools) within PSUs, and (3) students within sampled schools. Of the 72 PSUs, 8 were selected with certainty, 10 were selected with a probability of .50, and the remainder were selected with probability proportionate to the size of the senior class. In schools with more than 350 seniors, a random sample of seniors or classes was drawn. In schools with less than 350 seniors, all seniors were asked to participate. Each school was asked to participate for two years so that each year one-half of the sample is replaced. Schools refusing participation were replaced with similar schools in terms of geographic location, size, and type of school (e.g., public, private/Catholic, private/non-Catholic). The total sample was divided into six subsamples consisting of an average of 2,300 respondents, and each subsample was administered a different form of the questionnaire, although all respondents answered the "core" drug and demographic questions. The participation rate among schools has been between 66 and 85 percent since the inception of the study.

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
