  1. Prevention and treatment of drug dependence: new challenges and perspectives Gilberto Gerra Chief Health and Human Development Section UNODC

  2. PREVENT METHAMPHETAMINES USE AND TREAT METHAMPHETAMINES USE DISORDERS

  3. PREVENT COCAINE USE AND TREAT COCAINEDEPENDENCE

  4. PREVENT PRESCRIPTION DRUGS USE AND TREAT DEPENDENCE hydrocodone BZDs

  5. UNDERSTAND AND PREVENT combinations of psychedelics ‘…..Similar to combining DMT/DPT/5-MeO-DMT with ketamine, combining 4-acetoxy-DET with ketamine also provides an incredible synergy. Highly recommended for the cosmic-mystical near-death inclined!.....Xenon gas while on mushrooms or LSD comes in at a close second. ’ N,N-dimethyltryptamine (DMT) N,N-dipropyltryptamine (DPT) N,N-diethyltryptamine (DET) 5-methoxy-DMT (5-MeO-DMT) F. Schifano, 2008

  6. CANNABINOID AGONISTS DESIGNERS?

  7. Delay the age of onset significantly elevated ORs for a cannabis use disorder at each of teenage years (ages 12-18; range of ORs=3.9-7.2), (Winters and Lee, 2008) youths aged 12 to 17 have constituted about two thirds of the new marijuana users (OAS, 2001)

  8. PREVENT THE USE OF LEGAL DRUGS ALCOHOL AND TOBACCO

  9. Have drug dependence recognized as a disease

  10. Isolation and Social Status Can Change Neurobiology Brain DA D2 Receptors BecomesDominant No longer stressed Individually Housed Group Housed Becomes Subordinate Stress remains Morgan, D. et al. Nature Neuroscience, 5: 169-174, 2002.

  13. DRD2-TaqI A1 allele polymorphisms 30% methamphetamines controls abusers Higher novelty seeking scores among meth-abusers with allele A1 Han et al., 2008

  15. Heroin abuse was significantly associated with proenkephalin (PENK) polymorphic 3' UTR dinucleotide (CA) repeats 79% of subjects homozygous for the 79-bp allele were heroin abusers Nikoshkov et al., 2008

  16. Genetic risk Environmental risk substance use low levels of environmental risk may buffer against the potentially unfavorable effects of high familial risk temperament predicted substance use only through shared environmental factors Legrand et al., 1999

  17. Relevance of childhood neglect, 5-HTT gene variants and hypothalamus-pituitary-adrenal axis dysregulation to substance abuse susceptibility neglect 5HTT SS HPA axis Gerra et al., In press Risk of experimenting with illicit drugs

  18. Gerra et al., in press

  19. reduced maternal care perception was found to represent a key intermediate factor of the association between SS polymorphism and drug use, suggesting that genetic factors and parental behavior concur to drug use susceptibility Once controlled for CECA-Q scores the relative risk associated to the SS genotype drops strikingly

  20. Nilsson et al., 2005 adolescents with the S allele of the 5-HTT gene and with family relations being "neutral" or "bad" had a 12- to 14-fold increased risk for high alcohol intoxication frequency

  24. Adverse childhood experiences neglect abuse

  25. Monkeys who suffer maternal deprivationin childhood tend to be fearful, more aggressive, less exploratory, and subject to binge drinking on exposure to alcohol Early maternal deprivation reduces serotonin transporter Ichise et al., 2006

  26. - Childhood psychiatric disorders - Early onset adult psychiatric disorders Self-medication mechanism

  27. Addiction and premorbid psychiatric disorders: - social phobia - bipolar affective disorder - depression - anxiety - conduct disorder - oppositional defiant disorders were strongly associated with the subsequent development of substance dependence (attributable risks ranging from 44 to 86%) Merikangas and Avenevoli, 2000

  28. Arch Gen Psychiatry Prospective effects of attention-deficit/hyperactivity disorder, conduct disorder, and sex on adolescent substance use and abuse. Elkins et al., 2007 Hyperactivity/impulsivity predicts later substance problems, even after growth in later-emerging CD is considered Inattention alone poses less risk

  31. DRUG USE IS ONE OF THE TOP 20 RISK FACTORS TO HEALTHWORLDWIDE TOP 10 IN HIGH INCOME COUNTRIES HIV/AIDS HEPATITIS TUBERCULOSIS SUICIDE – PSYCHIATRIC DISORDERS CARDIOVASCULAR DISEASES OVERDOSE DEATHS 30% of HIV infection is due to injecting drug users when criminal activities related to drugs are included THE COST OF DRUG DEPENDENCE CAN AMOUNT TO 2% OF THE GDP

  32. …eliminating or reducing illicit demand for narcotic drugs and psychotropic substances with a view of reducing human suffering

  33. STOP PUNISHMENT AND UNETHICAL TREATMENT METHODS

  34. STOP VIOLATION OF HUMAN RIGHTS PRESENTED AS TREATMENT

  35. STOP MARGINALIZATION AND DISCRIMINATION

  36. - Reach individuals not motivated to treatment • Protect their health and respond to HIV epidemic • Provide unconditioned social assistance • Offer low threshold, accessible treatment • for drug dependence

  37. Provide a comprehensive package of harm reduction measures • reliable information and counseling • low-threshold pharmacological interventions (example opioid-agonists and antagonist • drugs) easily accessible • c. adequate social assistance for marginalized drug dependents • d. vaccination programmes against Hepatitis to all drug abusers • e. medication and emergency kits for management of overdoses in appropriate places • f. needle/syringe exchange programmes under sound medical practice • g. voluntary HIV counseling and testing, and antiretroviral treatment • prevention and services for the management of sexually transmitted infections for • drug abusers involved in sex work; • i. availability of measures to prevent acute consequences of stimulants abuse (free water…) • interventions in emergency rooms • well-equipped street-workers and peer outreach workers units • measures to prevent car and workplace accidents • social assistance for children of drug dependent individuals NOT IN ALTERNATIVE TO DEMAND REDUCTION BUT COMPLEMENTARY TO DEMAND REDUCTION

  38. BASIC FIRST LINE HEALTH/ SOCIAL ASSISTANCE SCHOOL INSTEAD OF STREET TREATMENT OF CONCOMITANT PSYCHIATRIC DISORDERS SUSTAINABLE LIVELIHOOD OPPORTUNITIES

  39. Estimated coverage of drug education in schools based ONLY on information Data from selected key countries in Asia, Latin America and Africa

  40. Estimated coverage of drug education in schools that is EVIDENCE-BASED Data from selected key countries in Asia, Latin America and Africa

  41. WHAT IS NOT WORKING IN PREVENTION scare tactics and moralistic appeals curricula that rely solely on information about drugs and their dangers curricula that only work to promote self-esteem and emotional well-being single shot assemblies testimonials by former addicts counseling in peer-group context recreation and community service activities Levine et al. 1999

  42. WHAT IS WORKING IN SCHOOL PREVENTION training in resistance skills normative education life skills: communication life skills: decision making life skills: emotional communication life skills: impulse control life skills: self esteem trained teacher interactive method Faggiano et al., Cochrane 2005

  43. interactive approaches life skill practice normative education, which portrays true use rates and corrects misperceptions positive school climates: a combination of clear policies and procedures, training and support for school staff, students and families and partnerships with community members Nancy Tobler (1992) Linda Dusenbury (1995)

  44. Parental care/neglect Trauma/abuse RISK RESILIENCE School connectedness Stress, post conflict, instability, poverty Bonding to the community Values and believes
