Alcohol and Drug Related Arrest Data
The Uniform Crime Reporting System is a national database for law enforcement programs to report arrests. The data represent reported crimes in the vicinity where the arrest occurred, rather than the area of residence of the arrestee. The reporting uses only four drug categories: 1) Opium, cocaine and their derivatives, 2) marijuana, 3) other dangerous non-narcotic drugs such as barbiturates and Benzedrine and 4) synthetic narcotics such as Demerol and methadone.
The arrests reported at this website represent the following types of crimes: homicide, aggravated assaults, sexual assaults, other assaults, robbery, burglary, larceny-theft, auto thefts, driving under the influence, violations of liquor laws, public drunkenness, stolen property, prostitution, and violations of drug laws. Note that some arrests are directly related to alcohol and drug use (e.g. public drunkenness) and others are indirectly related (e.g. homicide). The number of alcohol and drug-related arrests was determined by applying a fraction that represents the association that each type of arrest has with alcohol or drug use. For example, driving under the influence is directly related to alcohol use and violating drug laws is directly related to drug use. Each of these arrests were counted as one arrest in computing rate of alcohol and drug arrests, respectively. In contrast, larceny-theft is linked indirectly with alcohol use (.028 of an arrest) and drug use (.296 of an arrest), and was therefore counted as a fraction of a single arrest. The fractions, .028 and .296, were assigned to represent the proportion of larceny-theft arrests associated with prior alcohol and drug use, respectively. The alcohol and drug associated fractions used for the arrest data came from the FBI's Uniform Crime Reporting System.

After all associations with prior alcohol and drug use were computed, all alcohol-related and drug-related arrests were totaled.
Easy Access to FBI Arrest Statistics (EZAUCR – http://www.ojjdp.gov/ojstatbb/ezaucr/) presents arrest statistics at the national, state, and county level. Arrest statistics are presented for 29 detailed offense categories, including drug offenses. Users can select displays based on counts or rates for juveniles, adults, or all ages combined. Only data from jurisdictions that have coverage rates of 90-100% are considered reliable and are reported. Jurisdictions with less than 90-100% coverage are considered unreliable and are therefore not reported. The site includes sections on data coverage, Use the following links to obtain information on data coverage, methods, arrest stats, and data dictionary: Use the following link (http://www.ojjdp.gov/ojstatbb/ezaucr/asp/coverage.asp) to find out what jurisdictions within a particular state have reported data of sufficient quality (i.e., a coverage indicator at or above 90%) to be deemed reliable by the U.S. Department of Justice, Office of Juvenile Justice. Jurisdictions that meet this criterion are presented in bold. Use the pull down menu provided on the web site link above to select your area of interest.
