  5. Drugs of Abuse and Crime are Linked • Alcohol Use at Time of Offense1 • Violent crime: 37% state; 23% federal prison • Property crime: 37% state; 13% federal prison • Drug trafficking: 21% state: 19% federal prison • Costs3 • $107 Billion for Drug Related Crime • Regular Drug Use1 • 69% state, 64% federal prisoners • Drug Dependence/Abuse1, 2 • 53% jail; 53% state prison; 45% federal prison • Drug Use at Time of Offense1 • violent crime: 28% state; 24% federal prison • property crime: 39% state; 14% federal prison • drug trafficking: 42% state; 34% federal prison SOURCES: 1: BJS 2004 Survey of Prisoners (Mumola & Karberg, 2006/7); 2: BJS 2002 Survey of Jail Inmates (Karberg & James, 2005); 3:ONDCP, 2004

  6. Smoking in Criminal Justice • Rates of smoking 4 times higher in CJ than general population1, 2 • Among Prisoners: 70% males; 80% females smoke3 • 50% adolescentsin juvenile justice daily smokers2 • Smoking bans in prisons most prevalent intervention • 97% smokers relapse within 6 months of release to community4 SOURCES: 1: Cropsey & Kristeller, 2003; 2: Cropsey, Linker & Waite, 2008; 3: Conklin, Lincoln & Tuthill, 2000; 4: Lincoln et al, 2009

  13. Addressing Drugs and Crime Public Health Approach -disease -treatment Public Safety Approach -illegal behavior -punish HIGH ATTRITION HIGH RECIDIVSM

  14. Integrated Public Health-Public Safety Strategy Close supervision Community-based treatment Blends functions of criminal justice and treatment systems to optimize outcomes Opportunity to avoid incarceration or criminal record Consequences for noncompliance are certain and immediate

  15. Criminal Justice System:Key Participants and Intervention Opportunities ENTRY(Arrest) PROSECUTION(Court, Pre-Trial Release, Jail) ADJUDICATION(Trial) COMMUNITY REENTRY(Probation, Parole, Release) SENTENCING(Fines, Community Supervision, Incarceration) CORRECTIONS(Probation, Jail, Prison) Key Participants Crime victim Police FBI Probation Officers Correctional Personnel Crime victim Police FBI Judge Prosecutor Defense Attorney Defendant Jury Judge Judge Jury Probation/ Parole Officers Family Community-based providers Intervention Opportunities N/A Drug Court Terms of Incarceration Release Conditions Drug Treatment Drug Treatment Aftercare Housing Employment Mental Health Half-way House TASC Diversion Programs Drug Courts Community Treatment TASC Screening/Referral

  16. What is Addiction? • A common brain disease expressed as a compulsive behavior. • The continued use of a drug despite negative consequences • Often chronic with a high potential for relapse

  17. ADDICTION IS A DISEASE OF THE BRAIN …as other diseases it affects the tissue function Decreased Brain Metabolism in Drug Abuse Patient No Cocaine Abuse Cocaine Abuser High Decreased Heart Metabolism inHeart Disease Patient Healthy Heart No Heart Disease Diseased Heart Low SOURCES: From the laboratories of Drs. N. Volkow and H. Schelbert

  18. Key Question: Why Can’t Addicts Just Quit?

  19. Addiction is a Brain Disease Addiction comes about (by)… laying down and strengthening of new memory connections in various circuits in the brain. Long-lasting brain changes are responsible for the distortions of cognitive (thinking) and emotional functioning that characterize addicts, particularly including the compulsion to use drugs that is the essence of addiction.

  20. REWARD NAcc VP • Reward Circuit Drugs of Abuse Engage Systems in the Motivation Pathways of the Brain

  21. Reward Circuits Involved In Drug Abuse and Addiction

  22. Dopamine Movement Motivation Reward& well-being Addiction

  23. It’s About Dopamine (mostly) • Dopamine is brain’s primary “pleasure chemical” • Plays role in attention, problem solving, and anticipation of reward • Implicated in drug high and caving that accompanies withdrawal

  32. Even Unconscious Cues Can Elicit Brain Responses Brain Regions Activated by 33 millisecond Cocaine Cues (too fast for conscious recognition) SOURCE: Childress, et al, PLoS ONE 2008

  33. Circuits Involved In Drug Abuse and Addiction All of these brain regions must be considered in developing strategies to effectively treat addiction

  34. Effective Strategies Attend to Multiple Aspects of Addiction: • Biology • Behavior • Social Context

  35. Non-Addicted Brain Control STOP Saliency Drive Memory Treatments for Relapse Prevention: Medications Vaccines Enzymatic degradation Naltrexone DA D3 antagonists CB1 antagonists AddictedBrain Interfere with drug’s reinforcing effects Control Biofeedback Modafinil Bupropion Stimulants Executive function/ Inhibitory control Adenosine A2 antagonists DA D3 antagonists GO Strengthen prefrontal- striatal communication Drive Saliency Antiepileptic GVG N-acetylcysteine Interfere with conditioned memories Memory Cycloserine Teach new memories CRF antagonists Orexin antagonists Counteract stress responses that lead to relapse

  36. Non-Addicted Brain Control STOP Saliency Drive Memory Treatments for Relapse Prevention: Behavioral AddictedBrain Interfere with drug’s reinforcing effects Contingency Management Control Executive function/ Inhibitory control Cognitive Therapy GO Strengthen prefrontal- striatal communication Drive Saliency Motivation Therapies Interfere with conditioned memories Biofeedback Desensitization Memory Behavioral Therapies Teach new memories Counteract stress responses that lead to relapse Relaxation Behavioral therapies

  37. Principles of Drug Abuse Treatment For Criminal Justice Populations Drug addiction is a chronic brain disease that affects behavior: relapse rates are similar to other chronic medical conditions Recovery from drug addiction requireseffective treatment, followed by management of the problem over time Treatment must last long enough to produce stable behavioral changes Assessment is the first step in treatment

  39. What does recovery look like on average? • Months 1-12 of Abstinence: • More clean and sober friends • Less use, homelessness, violence and victimization • Less illegal activity and incarceration • Years 1-3 of Abstinence: • Virtual elimination of illegal activity and illegal income • Better housing and living situations • Increasing employment and income • Years 4-7 of abstinence: • More social and spiritual support • Better Mental Health • Housing and living situations continue to improve • Dramatic rise in employment and income • Dramatic drop in people living below the poverty line SOURCE: Dennis, Foss & Scott, 2007

  40. Principles of Drug Abuse Treatment For Criminal Justice Populations Drug addiction is a chronic brain disease that affects behavior: relapse rates are similar to other chronic medical conditions Recovery from drug addiction requireseffective treatment, followed by management of the problem over time Treatment must last long enough to produce stable behavioral changes Assessment is the first step in treatment

  41. Assessments over time used to measure ‘Risks/Needs/Progress’ • Early Recovery • Changes in • Thinking • Acting • Early • Engagement • Participation • Therapeutic Relationship • Treatment • Readiness: • Motivation • Anger/Hostility • Co-occurring Discharge Engagement (CEST/CAI) Engagement (CEST/CAI) Psychosocial(CEST/CAI) Psychosocial(CEST/CAI) Criminal Thinking(CTS) Criminal Thinking(CTS) Pre-release Risk (IPASS) Assessing Risks/Needs/Progress Engagement (CEST/CAI) Psychosocial(CEST/CAI) Psychosocial(CEST/CAI) Criminal Thinking(CTS) Criminal Thinking(CTS) Co-occurring (CODSI)

  42. Criminal Justice CEST

  43. Red Flag Red Flag Client: A 25th %tile 75th %tile Client Level Functioning Social Good? Criminal Thinking Engagement Psychological Motivation Good

  44. Specialized Interventions? Higher Criminal Thinking Lower Treatment Readiness Lower Psychological Functioning Lower Treatment Engagement Relationship between Hostility and Other Scales Higher Hostility: Red Flag

  45. Principles of Drug Abuse Treatment For Criminal Justice Populations Tailoring services to fit the needs of the individual is important: Match judicial supervision to individual risk and needs Drug use during treatment should be carefully monitored Treatment should target factors that are associated with criminal behavior – i.e., “criminogenic needs” including, but not limited to, substance abuse Criminal justice supervision should incorporate treatment planning for drug abusing offenders & treatment providers should be aware of correctional supervision requirements
