  1. Arrestees’ Drug Use Trajectories Using the ADAM Drug Use Calendar to Model Patterns of Illicit Drug Use Brad Myrstol University of Alaska Anchorage Justice Center

  2. Toward a developmental perspective The Drug–crime connection

  3. Drug Use – Criminal Behavior • Robust association between drug use and crime • How do we explain the association? • Drug use causes crime • Crime causes drug use • Drug use–crime correlation is spurious • At a minimum >>> complex relationship 4. Drug use–crime mutually reinforcing

  4. Developmental Trajectories • Great deal of drug use–crime research is correlational • Cross-sectional, binary indicators of use correlated with criminal behavior • Prior drug use (ever, past-year, past-month) • Intoxication (under the influence when offense occurred) • Phenomena don’t just “happen” all of a sudden • Most social, behavioral, biological processes evolveover time (Nagin, 2005) • Developmental approach conceptualizes drug use in terms of an evolving pattern of behavior • Examine the relationship between developmental of drug use and criminal offending, not drug use per se

  5. Adult male crack cocaine users An Example

  6. Data • Arrestee Drug Abuse Monitoring program (2000) • 35 sites (26 states + D.C.) • Adult Males (n=21,161) • “Ever used CRACK COCAINE?” • 32.7% (n=7,160) “Yes” • “Used CRACK COCAINE in past 12 months?” • 19.7% (n=4,170) “Yes” • Level of use, each month, past 12 months • Values: 0-3 • Cases with missing values dropped • 17.9% (n=3,801) of adult male sample • 53.1% of male arrestees who have used crack cocaine in lifetime • 91% of male arrestees who have used crack cocaine past year
