Students in each grade are randomly assigned to complete one of four questionnaires, each with a different subset of topical questions but containing a set of "core" questions on demographics and drug use. There are more than 500 variables across the questionnaires. Drugs covered by this survey include amphetamines (stimulants), barbiturates (tranquilizers), other prescription drugs, over-the-counter medications, tobacco, smokeless tobacco, vaping, alcohol, inhalants, steroids, marijuana, hashish, LSD, hallucinogens, cocaine, crack, ecstasy, methamphetamine, and injectable drugs such as heroin. Highlights for 2019: A supplemental data file (DS2) has been included this year by the Principal Investigators. This file includes 17 variables (6 administrative and 11 survey questions) and 93,034 cases from the years 2016 to 2018. These same 11 variables are already in the main data file (DS1) for 2019. The front section of the codebook provides details about each of the variables. There are also instructions on how to merge the supplemental data on to the main data files for the previous three years: K1 Alcohol K1 Attitudes K1 Delinquent Behavior K1 demographic characteristics K1 drug education K1 Drug use K1 educational objectives K1 Family relationships K1 Gender Roles K1 High school students K1 Lifestyles K1 Peer influence K1 Prescription Drugs K1 self esteem K1 Substance Abuse K1 Technology K1 Tobacco use K1 vaping K1 Victimization K1 Forschungsdaten DO 10.3886/ICPSR37842.v1
