Systematic Review and Meta-Analysis: Medical and Recreational Cannabis Legalization and Cannabis Use Among Youth in the United States.

OBJECTIVE: Dramatic changes in state-level cannabis laws (CL) over the past 25 years have shifted societal beliefs throughout the United States, with unknown implications for youth. In the present study, we conducted an updated systematic review and meta-analysis examining estimated effects of medical cannabis legalization (MCL) and recreational cannabis legalization (RCL) on past-month cannabis use among US youth. METHOD: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, followed by a subsequent meta-analysis investigating the associations between state-level cannabis laws (ie, MCL vs non-MCL, and RCL vs non-RCL) and past-month cannabis use prevalence among US adolescents and young adults. Supplemental analyses examined age-group effects and design-related factors. RESULTS: Our search identified 4,604 citations, 34 and 30 of which were included in qualitative and quantitative analyses, respectively. Meta-analysis of MCL studies identified no significant association between MCL and change in past-month youth cannabis use (odds ratio [OR] = 0.981, 95% CI = 0.960, 1.003). Meta-analysis of RCL studies showed significantly increased odds of past-month cannabis use (OR = 1.134, 95% CI = 1.116-1.153). Meta-analysis of more recent studies, however, showed a significantly increased odds of past-month cannabis use among both adolescents and young adults (OR = 1.089, 95% CI = 1.015,1.169, and OR = 1.221, 95% CI = 1.188,1.255, respectively). CONCLUSION: Cannabis legalization has complex and heterogenous effects on youth use that may differ across law types. Our meta-analytic results showed modest positive effects of RCL on past-month cannabis use (more so in young adults than in adolescents) and minimal effects of MCL on these outcomes in US youth. Given the shift toward recreational legalization, additional focus on RCL effects is warranted. PLAIN LANGUAGE SUMMARY: Cannabis laws have changed dramatically throughout the United States over the past 25 years. It is important to determine if medical or recreational cannabis legalization are associated cannabis use in youth. The authors conducted a systematic review and meta-analysis to investigate the associations between state-level cannabis laws and past-month cannabis use in adolescents and young adults. The authors identified 64 articles and found that recreational cannabis laws were associated with a modest but significant higher odds of past-month cannabis use. In contrast, medical cannabis laws were not associated with past-month youth cannabis use. Analysis of more recent studies suggested a rise in cannabis use among youth. The authors conclude that further research is needed to better understand the impact of recreational cannabis legalization on youth.

Different factors identified by stakeholder group for barriers and facilitators to measurement-based care implementation in behavioral health clinics.

INTRODUCTION: Despite the benefits of measurement-based care (MBC) in the behavioral health setting, there have been difficulties in implementation and low saturation. Although barriers and facilitators to MBC implementation have been identified, research has generally only included the perspective of one stakeholder group. The current study aims to examine the similarities and differences-by stakeholder group-in the identified barriers to and facilitators of implementing MBC in the behavioral health setting. METHOD: A purposeful sampling approach was used to recruit and conduct interviews and focus groups with stakeholders (clinicians, clinic leaders, and administrative staff) from four behavioral health clinics at an academic medical center that is part of a larger healthcare system. The data coding process included a directed content analytic approach whereby the coding team used an iterative process to analyze deidentified transcripts starting with a codebook based on the Consolidated Framework for Implementation Research (CFIR) constructs. RESULTS: A total of 31 clinicians, 11 clinic leaders, and 8 administrative staff participated in the interviews and focus groups. There was convergence among all stakeholder regarding which CFIR constructs were identified as barriers and facilitators, but there were differences in the specific thematic factors identified by stakeholders as barriers and facilitators within each of these implementation constructs. The barriers and facilitators that stakeholders identified within each CFIR construct were often connected to their specific role in implementing MBC. CONCLUSION: Collecting information on barriers and facilitators to MBC implementation from the multiple stakeholders involved in the process may enhance successful implementation of MBC given the variation between groups in identified thematic factors. Administrative staff perspectives, which have not been reported in the literature, may be of particular importance in planning for successful MBC implementation.

Substance Use Disorders and Psychiatric Illness Among Transitional Age Youth Experiencing Homelessness.

Objective: Transitional age youth experiencing homelessness (TAY-EH) bear a high burden of substance use disorders (SUDs) and psychopathology. However, limited data exist on the co-occurrence and interactions between these diagnoses in this marginalized group. This study sought to identify rates of single and co-occurring SUDs and psychiatric diagnoses among a sample of TAY-EH and to investigate associations between psychopathology and prevalence and severity of SUDs in this group. Method: TAY-EH accessing a low-threshold social service agency in a large metropolitan area completed psychosocial and diagnostic interviews to assess for SUDs and psychopathology. Analyses examined rates of single and co-occurring disorders and associations between burden of psychopathology and presence and severity of SUDs. Results: The assessment was completed by 140 TAY-EH; the majority were youth of color (54% Black/African American, 16% Latinx), and 57% identified as male. Rates of single and co-occurring psychiatric disorders and specific SUDs (cannabis use disorder [CUD] and alcohol use disorder [AUD]) were notably high. An increasing number of psychiatric diagnoses was significantly associated with elevated CUD/AUD prevalence and severity. Mood, anxiety, attention-deficit/hyperactivity, and antisocial personality disorders were significantly associated with elevated CUD/AUD prevalence and severity, as was suicidality (all p < .05). Conclusion: This study reveals a complex overlay of SUDs and psychopathology facing TAY-EH, with a significant association between co-occurring psychopathology and severity of CUD/AUD. To the authors' knowledge, this is the first study to examine associations between specific psychopathology and severity of SUDs among TAY-EH. Further research into the mechanistic and temporal links between these conditions is needed to inform tailored treatment interventions.

Systematic review: Rates of psychopathology, substance misuse, and neuropsychological dysfunction among transitional age youth experiencing homelessness.

BACKGROUND AND OBJECTIVES: Transitional age youth experiencing homelessness (TAY-EH) bear a disproportionate burden of morbidity and mortality related to psychopathology, substance use disorders (SUD), and neuropsychological dysfunction. Prior reviews examining these conditions are now nearly a decade old, have focused on younger adolescent populations, or have utilized nonsystematic approaches. To our knowledge, no prior reviews have reported on all three of these domains in an integrated fashion. Here, we provide a contemporary, critical synthesis of the literature on the functioning of TAY-EH in North America within these three domains. METHODS: Based upon PRISMA guidelines, a search of PubMed, Medline, and PsycInfo databases was conducted, including literature published between January 2015 and June 2021. RESULTS: The initial search yielded 2024 citations; 104 underwent full text review and 32 met inclusion criteria, with a final aggregate sample size of 13,516. Studies revealed elevated rates of mood disorders, PTSD, anxiety disorders, and alcohol misuse. There is insufficient data to draw generalizable conclusions regarding neuropsychological functioning, other SUD, or other psychiatric diagnoses. No studies reported on co-occurrence of disorders among or between the domains of psychopathology, SUD, and neuropsychological dysfunction. Four studies used structured interviews for diagnoses, with the remainder relying upon brief screeners or self-report measures. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: To our knowledge, this is the first systematic review to provide integrated findings on psychopathology, SUD, and neuropsychological dysfunction among TAY-EH. Further research using structured, DSM-based tools is needed to characterize rates of single and co-occurring conditions to inform tailored treatment interventions.

Pharmacotherapy of attention deficit/hyperactivity disorder in individuals with autism spectrum disorder: A systematic review of the literature.

AIM: To assess the empirical evidence for the treatment of attention deficit/hyperactivity disorder (ADHD) in populations with autism spectrum disorder (ASD). METHODS: A systemic PubMed, PsychINFO, Embase, and Medline database search of peer-reviewed literature was conducted. Included in the review were controlled trials published in English with sample sizes ⩾10 participants examining the safety and efficacy of anti-ADHD medication in ASD populations. Data was extracted on relevant variables of study design, demographics, associated psychopathology, medication dose, efficacy, and tolerability. RESULTS: Nine controlled trials met the inclusion and exclusion criteria: five with methylphenidate, three with atomoxetine, and one with guanfacine. Sample sizes ranged from 10 to 128 with 430 children participating across all the trials. In all the trials, treatment response was significantly superior to placebo. However, almost all trials assessed only hyperactivity, and most included only participants with intellectual disability with high levels of irritability. None of the trials distinguished agitation from hyperactivity. The response on hyperactivity for methylphenidate and atomoxetine was less than that observed in the neurotypical population; however, the response for guanfacine surpassed results observed in neurotypical populations. Treatment-emergent mood lability (i.e. mood dysregulation and mood-related adverse events) was frequently associated with methylphenidate and guanfacine treatments. Worse treatment outcomes were associated with individuals with lower intellectual capability compared with those with higher IQs. CONCLUSIONS: here is a scarcity of controlled trials examining ADHD treatments in ASD populations, particularly in intellectually capable individuals with ASD and in adults. Response to ADHD medications in ASD were adversely moderated by the presence of intellectual disability and mood lability.

Prior Authorizations: A Necessary Evil?

Along with general practice burdens, child and adolescent psychiatrists (CAPs) are commonly tasked with completing prior authorizations (PAs) for medications prescribed in clinical practice. CAPs frown in resignation to their PA requirements to allow patients to be initiated onto, or continue with, their medications. PAs are often required for both brand and generic prescription medications, sometimes to confirm if the medication is medically necessary and appropriate for the indication,1 to review medication dosages, or more commonly to review the need in context to the medication cost of the requested agent relative to less expensive alternatives. Some states have implemented policies that leverage PAs to regulate and oversee provider prescribing patterns. Notably, many state Medicaid programs have restrictions on prescription of antipsychotics in children, and adoption of these regulations has led to decreases in their use in children 6 to 12 years old.2.
