Alcohol use disorder

Alcohol is one of the most frequently used substances, and alcohol-related disorders are common, especially in western societies. While there is no safe lower drinking level, a clear dose–response relationship has been shown between alcohol intake and organ damage. Conceptualization and diagnostic classification of alcohol use disorders have changed over time, focusing most recently on aspects of craving, loss of control, and continued use despite negative consequences. Alcohol acts via various binding sites in the brain and via downstream effects, including glutamatergic, GABAergic, serotonergic, dopaminergic, opioid, and neuroendocrine pathways. For its long-lasting, habit-forming effects, sensitization within the mesolimbic–mesocortical system is crucial. Psychological treatments traditionally focus on motivational enhancement, cognitive behaviour therapy, and the community reinforcement approach. Pharmacological treatment approaches range from aversive and reward-inhibiting to anti-craving compounds and cognitive enhancers, which target opioid, glutamatergic, and monoamine receptors. Improvement of treatment effects can be achieved by polypharmacy and use of personalized medicine, based on clinical characteristics, biomarkers, and genetic indicators.

Retention and Treatment Outcome of Youth with Cannabis Use Disorder Referred By the Legal System

<P>Background: Youth with Substance Use Disorders (SUDs) referred to treatment from the Juvenile Justice System (JJS) account for approximately half of the treatment admissions nationwide. The objective of this paper is to report a comparison of retention and outcomes for JJS referrals to those from the general community. Methods: A total of 172 adolescents, 13-18 years of age, 83% males, 70% JJS referrals, diagnosed with DSM-IV Cannabis Use Disorder (CUD), enrolled in this outpatient, randomized, continued care study. Following a 7-session weekly motivational enhancement and cognitive behavioral therapy intervention (MET/CBT-7), only poor responders were randomized into a 10-week second phase of either an individualized enhanced CBT or an Adolescent Community Reinforcement Approach (ACRA) intervention. Results: JJS referrals’ retention rates were significantly higher than those of non-JJS referrals (X2(1) = 11.21, p < .01) at the end of Phase I (i.e. week 7). However, there was no difference in abstinence rates between the groups at the end of phase I or II and any of the quarterly additional follow-up assessments up to one year from treatment onset. </P><P> Conclusions: Additional research examining how to capitalize on improved retention rates among youth JJS referrals is necessary in order to advance abstinence.</P>
