IMPORTANCE
Despite growing interest in psychedelics, there is a lack of routine population-based surveillance of psychedelic microdosing (taking "subperceptual" doses of psychedelics, approximately one-twentieth to one-fifth of a full dose, over prolonged periods). Analyzing Google search queries can provide insights into public interest and help address this gap.
OBJECTIVE
To analyze trends in public interest in microdosing in the US through Google search queries and assess their association with cannabis and psychedelic legislative reforms.
DESIGN, SETTING, AND PARTICIPANTS
In this cross-sectional study, a dynamic event-time difference-in-difference time series analysis was used to assess the impact of cannabis and psychedelic legislation on microdosing search rates from January 1, 2010, to December 31, 2023. Google search rates mentioning "microdosing," "micro dosing," "microdose," or "micro dose" within the US and across US states were measured in aggregate.
EXPOSURE
Enactment of (1) local psychedelic decriminalization laws; (2) legalization of psychedelic-assisted therapy and statewide psychedelic decriminalization; (3) statewide medical cannabis use laws; (4) statewide recreational cannabis use laws; and (5) all cannabis and psychedelic use restricted.
MAIN OUTCOME AND MEASURES
Microdosing searches per 10 million Google queries were measured, examining annual and monthly changes in search rates across the US, including frequency and nature of related searches.
RESULTS
Searches for microdosing in the US remained stable until 2014, then increased annually thereafter, with a cumulative increase by a factor of 13.4 from 2015 to 2023 (7.9 per 10 million to 105.6 per 10 million searches, respectively). In 2023, there were 3.0 million microdosing searches in the US. Analysis at the state level revealed that local psychedelic decriminalization laws were associated with an increase in search rates by 22.4 per 10 million (95% CI, 7.5-37.2), statewide psychedelic therapeutic legalization and decriminalization were associated with an increase in search rates by 28.9 per 10 million (95% CI, 16.5-41.2), statewide recreational cannabis laws were associated with an increase in search rates by 40.9 per 10 million (95% CI, 28.6-53.3), and statewide medical cannabis laws were associated with an increase in search rates by 11.5 per 10 million (95% CI, 6.0-16.9). From August through December 2023, 27.0% of the variation in monthly microdosing search rates between states was explained by differences in cannabis and psychedelics legal status.
CONCLUSION AND RELEVANCE
This cross-sectional study found that state-led legislative reforms on cannabis and psychedelics were associated with increased public interest in microdosing psychedelics.

PURPOSE
Postpartum mood disorders affect many women following childbirth. Prescribing medication for depression and anxiety is one strategy for the effective treatment of postpartum mood disorders. Left untreated, mothers experiencing these disorders and their infants face increased risks of adverse health outcomes. Little is known about how diagnosis and treatment of postpartum mood disorders changed during COVID-19.
METHODS
We used a retrospective pooled cross-sectional design in a sample of privately-insured postpartum women in U.S. claims data from January 1, 2016 to December 31, 2020. We measured changes in diagnoses of anxiety and depression and changes in prescription fills and days supplied of classes of medications used to treat these conditions (antidepressants, benzodiazepines, and z-drugs). We used ordinary least squares (OLS) regression for each outcome variable during the pre-pandemic period and forecast expected outcomes the observation period. Forecasted and actual values of the outcomes were then compared.
RESULTS
Following the onset of the COVID-19 pandemic in March 2020, diagnoses of depression and anxiety were not significantly higher among privately insured postpartum women in the United States. The proportion of privately-insured postpartum women filling a benzodiazepine prescription increased by 15.2%.
CONCLUSIONS
We find diagnosis of postpartum mood disorders did not increase after the onset of the COVID-19 pandemic, however, fills of benzodiazepines increased among privately-insured postpartum women. Given prior evidence of increased depressive and anxiety symptoms among postpartum women during COVID-19, this suggests increased barriers to appropriate diagnoses and treatment for depression during this period.

Review
Medications for opioid use disorder (MOUD) reduce risks for overdose among correctional populations. Among other barriers, daily dosing requirements hinder treatment continuity post-release. Extended-release buprenorphine (XR-BUP) may therefore be beneficial. However, limited evidence exists. To conduct a systematic review examining the feasibility and effectiveness of XR-BUP among correctional populations. Searches were carried out in Pubmed, Embase, and PsychINFO in October 2023. Ten studies reporting on feasibility or effectiveness of XR-BUP were included, representing = 819 total individuals (81.6% male). Data were extracted and narratively reported under the following main outcomes: 1) Feasibility; 2) Effectiveness; and 3) Barriers and Facilitators. Studies were heterogeneous. Correctional populations were two times readier to try XR-BUP compared to non-correctional populations. XR-BUP was feasible and safe, with no diversion, overdoses, or deaths; several negative side effects were reported. Compared to other MOUD, XR-BUP significantly reduced drug use, resulted in similar or higher treatment retention rates, fewer re-incarcerations, and was cost-beneficial, with a lower overall monthly/yearly cost. Barriers to XR-BUP, such as side effects and a fear of needles, as well as facilitators, such as a lowered risk of opioid relapse, were also identified. XR-BUP appears to be a feasible and potentially effective alternative treatment option for correctional populations with OUD. XR-BUP may reduce community release-related risks, such as opioid use and overdose risk, as well as barriers to treatment retention. Efforts to expand access to and uptake of XR-BUP among correctional populations are warranted.

As resolution for opioid-related claims and litigation against pharmaceutical manufacturers and other stakeholders, state and local governments are newly eligible for millions of dollars of settlement funding to address the overdose crisis in the United States. To inform effective use of opioid settlement funds, we propose a simple framework that highlights the principal determinants of overdose mortality: the number of people at risk of overdose each year, the average annual number of overdoses per person at risk, and the average probability of death per overdose event. We assert that the annual number of overdose deaths is a function of these three determinants, all of which can be modified through public health intervention. Our proposed heuristic depicts how each of these drivers of drug-related mortality - and the corresponding interventions designed to address each term - operate both in isolation and in conjunction. We intend for this framework to be used by policymakers as a tool for identifying and evaluating public health interventions and funding priorities that will most effectively address the structural forces shaping the overdose crisis and reduce overdose deaths.

Previous research has indicated that various factors, such as psychological distress, distress intolerance, anhedonia, impulsivity and smoking metacognitions, have been individually linked to the urge to smoke, withdrawal symptoms and dependence. However, these factors have not been collectively examined to determine whether smoking metacognitions independently and significantly contribute to these outcomes. Therefore, the aim of this study was to investigate the impact of distress intolerance, anhedonia, impulsivity and smoking metacognitions on the urge to smoke, withdrawal symptoms and dependency in men who are dependent on smoking. A total of 300 smoking-dependent men completed psychological scales and smoking-related measures. The findings of the study indicated that positive metacognitions about emotion regulation significantly predicted the urge to smoke, even when accounting for other significant predictors such as the number of daily cigarettes smoked, psychological distress, anhedonia and impulsivity. Furthermore, positive metacognitions about cognitive regulation were found to be a significant predictor of withdrawal symptoms, independent of other significant predictors such as psychological distress and the urge to smoke. Smoking dependence was predicted by negative metacognitions about uncontrollability beyond other significant predictors, including the number of daily cigarettes smoked and distress intolerance. These results highlight the role of metacognitions about smoking in both short- and long-term clinical outcomes related to smoking. Consequently, addressing such beliefs during treatment for smoking dependence should be an important therapeutic goal.

A Tailored Virtual Program for Alcohol Use Disorder Treatment Among Liver Transplant Candidates and Recipients Is Feasible and Associated With Lower Post-Transplant Relapse.
BACKGROUND
Alcohol-associated liver disease (ALD) is a leading indication for liver transplant (LT) in the United States. Rates of early liver transplant (ELT) with less than 6 months of sobriety have increased substantially. Patients who receive ELT commonly have alcohol-associated hepatitis (AH) and are often too ill to complete an intensive outpatient program (IOP) for alcohol use disorder (AUD) prior to LT. ELT recipients feel alienated from traditional IOPs.
METHODS
We implemented Total Recovery-LT, a tailored virtual outpatient IOP specific for patients under evaluation or waitlisted for LT who were too ill to attend community-based alcohol treatment programs. The 12-week program consisted of weekly group and individual counseling delivered by a master's level Certified Addiction Counselor trained in the basics of LT. Treatment consisted of 12-Step Facilitation, Motivational Interviewing, and Cognitive Behavioral Therapy. We report on program design, implementation, feasibility and early outcomes.
RESULTS
From March 2021 to September 2022, 42 patients (36% female, 23 in LT evaluation, 19 post-transplant) enrolled across five cohorts with 76% (32/42) completing the program. Alcohol relapse was more common among noncompleters versus those who completed the program (8/10, 80% vs. 7/32, 22%, p = 0.002). History of trauma or post-traumatic stress symptoms were associated with lower likelihood of completion. Patients' desire for continued engagement after completion led to the creation of a monthly alumni group.
CONCLUSIONS
Our integrated IOP model for patients with high-risk AUD in LT evaluation or post-transplant is well-received by patients and could be considered a model for LT programs.

BACKGROUND
Alcohol abuse, a prevalent global health issue, is associated with the onset of cognitive impairment and neurodegeneration. Actin filaments (F-actin) and microtubules (MTs) polymerized from monomeric globular actin (G-actin) and tubulin form the structural basis of the neuronal cytoskeleton. Precise regulation of the assembly and disassembly of these cytoskeletal proteins, and their dynamic balance, play a pivotal role in regulating neuronal morphology and function. Nevertheless, the effect of prolonged alcohol exposure on cytoskeleton dynamics is not fully understood. This study investigates the chronic effects of alcohol on cognitive ability, neuronal morphology and cytoskeleton dynamics in the mouse hippocampus.
METHODS
Mice were provided access to 5% (v/v) alcohol in drinking water and were intragastrically administered 30% (v/v, 6.0 g/kg/day) alcohol for six weeks during adulthood. Cognitive functions were then evaluated using the Y maze, novel object recognition and Morris water maze tests. Hippocampal histomorphology was assessed through hematoxylin-eosin (HE) and Nissl staining. The polymerized and depolymerized states of actin cytoskeleton and microtubules were separated using two commercial assay kits and quantified by Western blot analysis.
RESULTS
Mice chronically exposed to alcohol exhibited significant deficits in spatial and recognition memory as evidenced by behavioral tests. Histological analysis revealed notable hippocampal damage and neuronal loss. Decreased ratios of F-actin/G-actin and MT/tubulin, along with reduced levels of polymerized F-actin and MTs, were found in the hippocampus of alcohol-treated mice.
CONCLUSIONS
Our findings suggest that chronic alcohol consumption disrupted the assembly of the actin cytoskeleton and MTs in the hippocampus, potentially contributing to the cognitive deficits and pathological injury induced by chronic alcohol intoxication.

Since January 2020, Medicare has covered opioid use disorder (OUD) treatment services at opioid treatment programs (OTPs), the only outpatient settings allowed to dispense methadone for treating OUD. This study examined policy-associated changes in Medicare acceptance and the availability of four OUD treatment services (ongoing buprenorphine, HIV/AIDS education, employment services, and comprehensive mental health assessment), by for-profit status, and county-level changes in Medicare-accepting-OTPs access, by sociodemographic characteristics (racial composition, poverty rate, and rurality). Using data from the 2019-2022 National Directory of Drug and Alcohol Abuse Treatment Facilities, we found Medicare acceptance increased from 21.31% in 2018 to 80.76% in 2021. The availability of the four treatment services increased, but no increases were significantly associated with Medicare coverage. While county-level OTP access significantly improved, counties with higher rates of non-White residents experienced an additional average increase of 0.86 Medicare-accepting-OTPs (95% CI, 0.05-1.67) compared to those without higher rates of non-White populations. Overall, Medicare coverage was associated with improved OTP access, not ancillary services.
