RESUMO
INTRODUCTION: While there is increasing interest in the use of cannabis to manage a range of health-related symptoms, little is known about trends in recent cannabis use with respect to various health conditions. METHODS: We examined data from a US representative sample of noninstitutionalized adults age ≥ 18 from the 2015-2019 National Survey on Drug Use and Health (N = 214,505). We estimated the pooled prevalences followed by linear time trends, overall, and by disability (i.e., difficulty hearing, seeing, thinking, walking, dressing, doing errands) and lifetime (i.e., bronchitis, cancer, diabetes, hepatitis, kidney disease) and current (i.e., asthma, depression, heart disease, hypertension) health condition status using logistic regression. Models with year-by-condition status interaction terms were used to assess differential time trends, adjusting for demographic characteristics. RESULTS: From 2015 to 2019, cannabis use increased significantly among adults with and without each disability and health condition examined. However, the increase was more rapid among those with (versus without) difficulty hearing (89.8% increase [4.9% to 9.3%] vs. 37.9% increase [8.7% to 12.0%], p = 0.015), difficulty walking (84.1% increase [6.3% to 11.6%] vs. 36.8% increase [8.7% to 11.9%], p < 0.001), 2-3 impairments (75.3% increase [9.3% to 16.3%] vs. 36.6% increase [8.2% to 11.2%], p = 0.041), and kidney disease (135.3% increase [3.4% to 8.0%] vs. 38.4% increase [8.6% to 11.9%], p = 0.045). CONCLUSION: Given the potential adverse effects of cannabis, prevention and harm reduction efforts should focus on groups at increasingly higher risk for use, including those with disabilities and kidney disease.

Cannabis use is growing among older adults to manage medical concerns including poor sleep. In this study, we characterized how patients seen at a geriatrics clinic use cannabis to address sleep disturbance. Specifically, we conducted an anonymous survey of 568 adults, including 83 who reported cannabis use within the past 3 years, to inquire about such use. We compared cannabis use characteristics between those using it for sleep disturbance versus all other conditions. We considered a p-value <.10 to be statistically significant. Among the cannabis users in our sample, 29% reported using cannabis for sleep disturbance (N = 24). They were more likely than other users to be female (p = .07), consume cannabis more frequently (p = .01), use products containing tetrahydrocannabinol (THC) (vs. cannabidiol [CBD]-only; p < .01), and use cannabis to target more symptoms (p < .01). As cannabis use continues to grow in older populations, it is essential to delineate better how cannabis may be used safely and effectively to improve older adults' sleep health.

BACKGROUND AND OBJECTIVES: Ketamine is efficacious in treating treatment-resistant depression in medical settings and the drug was approved for such use by the US Federal Drug Administration in 2019. However, little is known about how use outside of medical settings relates to depression. We determined whether recreational ketamine use, relative to the use of other drugs, is related to the current experience of depression among adolescents. METHODS: We examined data from the 2016 to 2019 Monitoring the Future nationally representative survey of high school seniors in the United States (N = 15,673). We determined how past-year drug use and frequency of past-year drug use were associated with students reporting a high level of current depressive symptoms relative to other students. RESULTS: Ketamine use was associated with highest risk for a high level of depression (aPR = 1.55, 95% confidence interval [CI]: 1.24-1.94), followed by use of cannabis (aPR = 1.29, 95% CI: 1.19-1.39), and nonmedical use of tranquilizers (aPR = 1.22, 95% CI: 1.04-1.44) and amphetamine (aPR = 1.17, 95% CI: 1.01-1.34). Alcohol use was associated with decreased risk (aPR = 0.92, 95% CI: 0.85-0.99). With respect to frequency of past-year use, more frequent use of ketamine and cannabis was associated with increased risk for a high level of depression in a dose-response-like manner, with past-year use of ketamine and cannabis ≥10 times associated with increased risk for depression by 70% and 40%, respectively. DISCUSSION AND CONCLUSIONS: Past-year recreational ketamine use is a risk factor for reporting current depression than most other drugs. SCIENTIFIC SIGNIFICANCE: This was the first study to compare the risk of use of various drugs in relation to depression.

INTRODUCTION: Cannabis use and cannabis use disorder (CUD) are associated with adverse psychosocial outcomes, but their impact on workplace absenteeism remains poorly understood. Moreover, few studies have examined the role of CUD severity. This study aims to address these gaps by examining the associations between cannabis use recency, frequency, CUD severity, and workplace absenteeism. METHODS: Cross-sectional data from a U.S. representative sample of full-time employed adults aged ≥18 from the 2021 to 2022 National Survey on Drug Use and Health (N=46,499) were analyzed. The associations between cannabis use recency, past-month cannabis use frequency, CUD severity, and workplace absenteeism (measured by self-reported number of missed days due to illness/injury and skipped work in the last 30 days) were evaluated using negative binomial regression, adjusting for sociodemographic characteristics and other substance use. Data were analyzed in 2023-2024. RESULTS: An estimated 15.9% of full-time employed adults used cannabis in the past month, with 6.5% meeting CUD criteria. Past-month cannabis use (compared to no lifetime use), more frequent past-month cannabis use (compared to no use in the past month), and each level of CUD (compared to no CUD) were associated with increased incidence of both missing work due to illness/injury and skipping work, with a dose-response relationship observed between CUD severity and skipping work (mild: adjusted incident rate ratio [aIRR]=1.60 [95% confidence interval [CI]=1.24, 2.08]; moderate: aIRR=1.98 [95% CI=1.50, 2.61]); severe (aIRR=2.87 [95% CI=2.12, 3.88]). CONCLUSIONS: Individuals with recent and frequent cannabis use and CUD are disproportionately prone to workplace absenteeism. Results support the enforcement of workplace drug prevention and treatment policies.
RESUMO
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.

ABSTRACT: Psychedelic serotonergic agonists such as psilocybin have recently been shown to produce sustained benefit in refractory depression, end of life anxiety, and addiction when administered in hallucinogenic doses and coupled with psychotherapy. Although it has been suggested that similar high-dose protocols may help chronic pain conditions, there are few published clinical trials of psychedelics for pain. The use of these agents in subpsychedelic doses for chronic pain management has received even less attention. This case series details the experiences of 3 individuals who have used low-dose psilocybin to manage chronic neuropathic pain. Although the nature and etiology of each patient's pain vary, they share a common experience, including inefficacy of current therapeutics and decreased quality of life. Through self-administration of psilocybin, these patients have achieved robust pain relief with decreased reliance on traditional analgesic medications. Despite varying preparations and uncertain potencies, the analgesic effects for all 3 patients occurred at doses without a psychedelic experience and with minimal cognitive or somatic adverse effects. Furthermore, the efficacy of pain relief and, in some cases, the duration of the effect were magnified when coupled with functional exercise. In addition, in 1 case, repeated dosing seemed to produce increased relief, suggesting a possible long-term plasticity-mediated effect. These commonalities highlight psilocybin's therapeutic potential in the treatment of chronic pain that warrants further investigation.

OBJECTIVES: 3,4-Methylenedioxymethamphetamine (MDMA) (also known as "ecstasy" or "Molly") has regained attention in recent years for its efficacy in treating posttraumatic stress disorder, and the drug was granted breakthrough therapy designation for such use by the US Food and Drug Administration in 2017. However, little is known about the current epidemiology of recreational ecstasy/MDMA use. METHODS: We estimated past-year prevalence and correlates of ecstasy/MDMA use based on a representative sample of noninstitutionalized US individuals 12 years or older from the 2015-2020 National Survey on Drug Use and Health (N = 315,661). RESULTS: An estimated 0.9% (95% confidence interval [CI] = 0.9-1.0) of individuals used ecstasy/MDMA in the past year. Compared with those ages 35-49 years, all younger age groups were at increased odds for use, while those older than 50 years (adjusted odds ratio [aOR] = 0.14, 95% CI = 0.08-0.23) were at low odds for use. Compared with heterosexual men, those identifying as bisexual women (aOR = 1.32, 95% CI = 1.02-1.72) were at increased odds for use, and compared with White individuals, those identifying as Asian (aOR = 1.92, 95% CI = 1.42-2.59), Black (aOR = 1.70, 95% CI = 1.41-2.06), or multiracial (aOR = 1.61, 95% CI = 1.19-2.16) were at increased odds for use. Past-year use of other drugs (e.g., cannabis, ketamine), prescription drug misuse (e.g., pain relievers, stimulants), nicotine dependence (aOR = 1.21, 95% CI = 1.00-1.45), and alcohol use disorder (aOR = 1.41, 95% CI = 1.25-1.58) were also associated with increased odds for use. CONCLUSIONS: While use of ecstasy/MDMA continues to be relatively rare, findings from this study can help inform prevention and harm reduction strategies, especially among certain subpopulations that are at high risk for use.

BACKGROUND: There is renewed interest in the clinical application of hallucinogenic substances to treat a range of psychiatric conditions. However, there is mixed evidence regarding how use of such substances outside of medical settings relates to psychological distress, depression, and suicidality. METHODS: We examined data from a US representative sample of noninstitutionalized adults from the 2015-2020 National Survey on Drug Use and Health (Nâ¯=â¯241,675). We evaluated whether past-year use of specific hallucinogens (i.e., LSD, DMT/AMT/Foxy, salvia divinorum, ecstasy [MDMA/Molly], ketamine) is associated with reporting past-year serious psychological distress (SPD), major depressive episode (MDE), and suicidality. Generalized linear models using Poisson and log link were used to estimate adjusted prevalence ratios (aPRs), controlling for sociodemographic characteristics and past-year use of various other illegal drugs. RESULTS: LSD use was associated with an increased likelihood of MDE (aPRâ¯=â¯1.23, 95% CI: 1.10-1.37) and suicidal thinking (aPRâ¯=â¯1.21, 95% CI: 1.09-1.34). Similar associations were observed between salvia divinorum use and suicidal thinking (aPRâ¯=â¯1.41, 95% CI: 1.00-1.97) and between DMT/AMT/Foxy use and suicidal planning (aPRâ¯=â¯1.81 95% CI: 1.17-2.81). On the other hand, ecstasy use was associated with a decreased likelihood of SPD (aPRâ¯=â¯0.83, 95% CI: 0.77-0.89), MDE (aPRâ¯=â¯0.91, 95% CI: 0.83-1.00), and suicidal thinking (aPRâ¯=â¯0.86, 95% CI: 0.75-0.99). CONCLUSION: Findings suggest there are differences among specific hallucinogens with respect to depression and suicidality. More research is warranted to understand consequences of and risk factors for hallucinogen use outside of medical settings among adults experiencing depression or suicidality.

Neuroendocrine cell hyperplasia of infancy (NEHI) is a rare childhood interstitial lung disease characterized by a gradual onset of tachypnea, hypoxemia, and failure to thrive in the first 2 years of life. NEHI is challenging to diagnose and can masquerade as common respiratory infections and reactive airway disease. Timely diagnosis is essential to optimize management of comorbidities, improve outcomes, and prevent unnecessary interventions. We report a case of a 14-month-old male who was hospitalized multiple times with recurrent episodes of presumed bronchiolitis. However, early on, the parents had detected unexplained nighttime hypoxemia with a wearable home pulse oximetry baby monitor. While recurrent respiratory infections are common in infancy, our patient had numerous persistent symptoms refractory to traditional treatments, which prompted further workup and ultimately led to the diagnosis of NEHI. The home baby monitor provided useful information that accelerated workup for a presentation that did not fit the usual picture of recurrent bronchiolitis, bronchospasm, or pneumonia. These devices that monitor infant cardiopulmonary status and oxygenation are becoming increasingly popular for home use. There is controversy over their clinical utility due to the frequency of false alarms, excessive parental reliance on these devices, and lack of Food and Drug Administration oversight to ensure accuracy and effectiveness of these devices. Our case provides an example of how in certain clinical settings, information from these devices might serve as a complementary tool in the pediatrician's medical decision-making and possibly lead to a rare diagnosis such as NEHI.
RESUMO
BACKGROUND: Despite concerns about increasing trends in depression over the past two decades, little is known about recent trends in depression and mental health (MH) treatment among older adults and whether these trends differ by demographic characteristics. METHODS: We examined data from a US representative sample of noninstitutionalized adults aged ≥65 from the 2010-2019 National Survey on Drug Use and Health (N = 31,502). We estimated trends in the prevalence of past-year major depressive episode (MDE) overall and by demographic characteristics. We also estimated trends in MH treatment among those with past-year MDE. RESULTS: From 2010/11 to 2018/19, the estimated prevalence of past-year MDE among older adults increased from 2.0 % (95 % CI: 1.6-2.6) to 3.2 % (95 % CI: 2.7 to 3.7), a 60.0 % increase (p = 0.013). Increases were detected among men (p = 0.038), White individuals (p = 0.018), those who are widowed (p = 0.003), those with an annual household income of <$20,000 (p = 0.020) or $20,000-$49,000 (p = 0.016), and those with some college degree (p = 0.014). Among those with MDE, there were no significant changes detected in any form of past-year MH treatment. LIMITATIONS: NSDUH does not assess individuals who are institutionalized, incarcerated, or experiencing homelessness, and thus the prevalence of MDE may be underestimated. CONCLUSIONS: Although the estimated prevalence of depression is increasing among older adults, there has not been a proportional increase in MH treatment among those with depression. These findings call for urgent expansion of treatment services and training of MH professionals with expertise in older adults to meet the needs of this growing, vulnerable population.

BACKGROUND/OBJECTIVES: Use of cannabis is increasing in a variety of populations in the United States; however, few investigations about how and for what reasons cannabis is used in older populations exist. DESIGN: Anonymous survey. SETTING: Geriatrics clinic. PARTICIPANTS: A total of 568 adults 65 years and older. INTERVENTION: Not applicable. MEASUREMENTS: Survey assessing characteristics of cannabis use. RESULTS: Approximately 15% (N = 83) of survey responders reported using cannabis within the past 3 years. Half (53%) reported using cannabis regularly on a daily or weekly basis, and reported using cannabidiol-only products (46%). The majority (78%) used cannabis for medical purposes only, with the most common targeted conditions/symptoms being pain/arthritis (73%), sleep disturbance (29%), anxiety (24%), and depression (17%). Just over three-quarters reported cannabis "somewhat" or "extremely" helpful in managing one of these conditions, with few adverse effects. Just over half obtained cannabis via a dispensary, and lotions (35%), tinctures (35%), and smoking (30%) were the most common administration forms. Most indicated family members (94%) knew about their cannabis use, about half reported their friends knew, and 41% reported their healthcare provider knowing. Sixty-one percent used cannabis for the first time as older adults (aged ≥61 years), and these users overall engaged in less risky use patterns (e.g., more likely to use for medical purposes, less likely to consume via smoking). CONCLUSION: Most older adults in the sample initiated cannabis use after the age of 60 years and used it primarily for medical purposes to treat pain, sleep disturbance, anxiety, and/or depression. Cannabis use by older adults is likely to increase due to medical need, favorable legalization, and attitudes.
