Access to and use of cannabis in the United States has increased as new product types emerge in the marketplace, and as additional states legalize its use for medical and nonmedical purposes. To tailor education messages for preventing adverse health effects of cannabis use, understanding the routes of use of these products in the general population is important. The 2022 Behavioral Risk Factor Surveillance System included a newly revised optional marijuana module comprising questions on marijuana routes of use among adults aged ≥18 years who used marijuana during the past 30 days (current use). Twenty-two states and two territories administered the optional marijuana module in 2022. Weighted prevalences (with 95% CIs) of current and daily or near-daily marijuana use, as well as prevalence of each route of use, were reported overall and by demographic characteristics and, among women aged ≤49 years, by pregnancy status. Among the 15.3% of respondents who reported current marijuana use, smoking was the most frequent route (79.4%), followed by eating (41.6%), vaping (30.3%), and dabbing (inhaling heated concentrated cannabis) (14.6%). Vaping and dabbing were most prevalent among persons aged 18-24 years. Intervention measures intended for persons who smoke cannabis are important; however, understanding health outcomes associated with other routes of use might have substantial public benefit.
Legalization by states of medical and non-medical cannabis use is increasing the accessibility of cannabis to Americans. While cannabis use remains illegal for youth, enhanced effective approaches preventing youth’s cannabis use are important. The Drug-Free Communities (DFC) Support Program is administered by the White House Office of National Drug Control Policy and represents the nation’s leading effort to mobilize communities to prevent and reduce youth substance use. Coalitions use the Seven Strategies for Community Change to ensure the creation of comprehensive action plans and a community-wide approach for preventing youth substance use. This study’s objective is to review the cannabis programmatic activities implemented by DFC coalitions, identify common themes, and assess whether activities align with the Seven Strategies for Community Change. Review of biannual progress report (PR) data collected from August 2020 to February 2021 was conducted to determine common themes, strengths, and areas of improvement among cannabis programmatic activities. Of the 727 funded coalitions, 73
OBJECTIVE:Historically, cannabis use and cannabis use disorder (CUD) have been more prevalent among males than among females. However, emerging evidence suggests that cannabis use may be increasing faster among females in younger age groups. This study characterized changes in female versus male differences in cannabis use and CUD across age groups and time. METHOD:Annual data from the 2014-2023 National Surveys on Drug Use and Health (NSDUH) were analyzed by age groups (12-17 [adolescents], 18-25 years, and 26 years or older) for past-month cannabis use, past-year daily/near-daily cannabis use (300 or more days), and past-year CUD. Prevalence differences (PDs) in percentage points between females and males were evaluated using generalized linear models. RESULTS:From 2014 to 2023, the prevalence of cannabis use (past-month and daily/near daily) and CUD increased among adults, with shifts in PDs across age groups. In 2022, adolescent females surpassed males in past-month cannabis use (PD = 2.3; 95% CI [1.0, 3.6]). By 2023, both daily/near-daily use and CUD prevalence were higher among adolescent females (e.g., CUD PD = 2.4; 95% CI [1.4, 3.4]). Among adults ages 18-25, all outcomes remained lower among females, but PDs narrowed over the study period. In adults age 26 years or older, females consistently had lower prevalence across all outcomes. CONCLUSIONS:Results showed reversals in female versus male differences among adolescents and narrowing gaps among younger adults. Tailored interventions considering sex and age may prevent and reduce CUD. Further research is needed to understand the reasons behind these shifts.
This cross-sectional study investigates county-level sociodemographic characteristics of patients who use medical cannabis and their authorizing physicians in 7 US states.
INTRODUCTION:Alcohol consumption during pregnancy can cause fetal alcohol spectrum disorders and may increase the risk of adverse pregnancy outcomes, such as miscarriage and stillbirth. It is unknown whether legalization of cannabis influences alcohol consumption during pregnancy. This analysis estimates the association between state implementation of legal nonmedical cannabis retail sales and alcohol consumption during pregnancy. METHODS:Data from the 2011 to 2023 Behavioral Risk Factor Surveillance System were analyzed in 2023-2024. Adjusted prevalence ratios comparing current and binge drinking during pregnancy in states after implementation of legal nonmedical cannabis retail sales with those in states before or without implementation were estimated, adjusting for demographic factors. Difference-in-difference analyses, which adjusted for state and time variability, estimated the association between the implementation of legal nonmedical cannabis retail sales and the change in current and binge drinking during pregnancy, controlling for selected demographic and policy variables. RESULTS:Prevalence of current and binge drinking during pregnancy were 1.43 (95% CI=1.18, 1.73) and 2.13 (95% CI=1.47, 3.09) times higher, respectively, among respondents in states with implementation of legal nonmedical cannabis retail sales than among respondents in states before or without implementation. Implementation of legal nonmedical cannabis retail sales was significantly associated with a 4.96 (95% CI=1.22, 8.70) percentage point increase in binge drinking and a nonsignificant change in current drinking of 3.18 (95% CI= -1.03, 7.39) percentage points. CONCLUSIONS:Alcohol consumption among pregnant women may be higher where legal nonmedical cannabis retail sales has been implemented, and implementation may be associated with an increase in binge drinking among pregnant women. Improving alcohol screening and counseling during pregnancy and patient education may be considered.
BackgroundAlthough substance use rates among adolescents have decreased, drug overdose deaths among adolescents have increased since 2020, driven largely by illegally made fentanyl (IMF). This study explores substance use patterns and characteristics of adolescents who were assessed for substance use disorder (SUD) treatment to inform prevention and response strategies.MethodsA convenience sample of adolescents aged 10-18 years assessed for SUD treatment from September 2017 to December 2021 was analyzed using the Comprehensive Health Assessment for Teens. The percentage of lifetime and past 30-day substance use was examined. Adolescent characteristics (e.g., demographics, history of overdoses or hospital visits due to drug/alcohol use) were analyzed by lifetime substances used.ResultsAmong 5,377 assessments, most were male (58.7%), aged 16-18 years (50.5%), non-Hispanic White (43.1%), enrolled in school (87.3%), and living with their parent(s) (72.4%). The most commonly reported lifetime substances used were marijuana (68.0%), alcohol (54.2%), and prescription opioid misuse (13.6%). The most common past 30-day substance use combination was alcohol and marijuana (35.6%). The percentage of assessments indicating past-year overdoses or hospital visits due to drug/alcohol use was greatest among those who reported lifetime use of IMF (24.0%), followed by heroin (21.4%) and cocaine (15.3%). Overall, 2.3% reported lifetime IMF use and 0.6% thought IMF was causing them the most problems.ConclusionsFindings inform opportunities to address substance use and increased IMF-involved overdose among adolescents. Continued overdose prevention and response strategies such as evidence-based education campaigns, naloxone distribution and harm reduction efforts, and evidence-based SUD treatment expansion are needed.
Background: As medical cannabis availability increases, up-to-date trends in medical cannabis licensure can inform clinical policy and care. Objective: To describe current trends in medical cannabis licensure in the United States. Design: Ecological study with repeated measures. Setting: Publicly available state registry data from 2020 to 2022. Participants: People with medical cannabis licenses and clinicians authorizing cannabis licenses in the United States. Measurements: Total patient volume and prevalence per 10 000 persons in the total population, symptoms or conditions qualifying patients for licensure (that is, patient-reported qualifying conditions), and number of authorizing clinicians. Results: In 2022, of 39 jurisdictions allowing medical cannabis use, 34 reported patient numbers, 19 reported patient-reported qualifying conditions, and 29 reported authorizing clinician numbers. Enrolled patients increased 33.3% from 2020 (3 099 096) to 2022 (4 132 098), with a corresponding 23.0% increase in the population prevalence of patients (175.0 per 10 000 in 2020 to 215.2 per 10 000 in 2022). However, 13 of 15 jurisdictions with nonmedical adult-use laws had decreased enrollment from 2020 to 2022. The proportion of patient-reported qualifying conditions with substantial or conclusive evidence of therapeutic value decreased from 70.4% (2020) to 53.8% (2022). Chronic pain was the most common patient-reported qualifying condition in 2022 (48.4%), followed by anxiety (14.2%) and posttraumatic stress disorder (13.0%). In 2022, the United States had 29 500 authorizing clinicians (7.7 per 1000 patients), 53.5% of whom were physicians. The most common specialties reported were internal or family medicine (63.4%), physical medicine and rehabilitation (9.1%), and anesthesia or pain (7.9%). Limitation: Missing data (for example, from California), descriptive analysis, lack of information on individual use patterns, and changing evidence base. Conclusion: Enrollment in medical cannabis programs increased overall but generally decreased in jurisdictions with nonmedical adult-use laws. Use for conditions or symptoms without a strong evidence basis continues to increase. Given these trends, more research is needed to better understand the risks and benefits of medical cannabis.
Objectives. To investigate characteristics of data reported in US medical cannabis registries across states. Methods. Data included 2021 medical cannabis registry reports from 34 states, Puerto Rico, and the District of Columbia (hereafter, states) with active medical cannabis programs. The data from the reports were manually coded into domains and subcategories, including information related to patients (e.g., number, demographics), authorizing clinicians, sales (e.g., content, revenue), license tracking, and health and safety outcomes. Results. Among 36 states, 97% reported total patient number and 75% reported number of authorizing clinicians. Least reported subcategories included patient race/ethnicity (8%), adverse events (11%), therapeutic benefits (6%), and product recalls (6%). States that recently legalized medical cannabis (2013-2018) reported a higher number of subcategories overall, with a median of 11 versus 8 for early adopting states (1996-2012). More medical-use states reported data on authorizing clinicians compared with nonmedical adult-use states but were otherwise similar. Conclusions. Medical cannabis state registries generally reported data on consumers, clinicians, and sales rather than health and safety outcomes. More comprehensive and uniform medical cannabis public health surveillance is needed. ( AmJ Public Health. 2024;114(S8):S685-S693. https://doi.org/ 10.2105/AJPH.2024.307728)
Delta-8 tetrahydrocannabinol (THC) is a psychoactive cannabinoid from the cannabis plant that can be synthetically converted from cannabidiol (CBD). Most states permit the full or restricted sale of hemp and hemp-derived CBD products, and therefore, delta-8 THC products are on the rise. Delta-8 THC consumption can cause intoxication. Products are often sold in edible form and occasionally in packaging that appears similar to candy. Clinical presentations for delta-8 THC ingestions are understudied and may differ from those described for delta-9 THC ingestions. This case report describes unintentional ingestions of putative delta-8 THC by two pediatric patients that results in admission to the pediatric intensive care unit. The ingestions were of putative delta-8 THC infused product that resembled popular candies. Both patients developed periods of bradypnea with continued intermittent periods of agitation. Medical intervention included observation, noninvasive positive pressure ventilation via high flow nasal cannula, and intubation—but was not needed for both patients. Although family noted ongoing irritability for the patients, both were discharged approximately 45 h after ingestion. Delta-8 THC ingestion is reliant on self-report. As the availability of delta-8 THC increases, along with associated pediatric exposures, it is imperative for health care providers to quickly recognize and provide adequate treatment. While there is no specific antidote for THC intoxication beyond supportive care, providers can play an important role in prevention by educating parents and guardians on safe cannabis storage and by documenting cases for adverse event monitoring.
BackgroundDelta-8 tetrahydrocannabinol (THC) is a psychoactive cannabinoid found in small amounts naturally in the cannabis plant; it can also be synthetically produced in larger quantities from hemp-derived cannabidiol. Most states permit the sale of hemp and hemp-derived cannabidiol products; thus, hemp-derived delta-8 THC products have become widely available in many state hemp marketplaces, even where delta-9 THC, the most prominently occurring THC isomer in cannabis, is not currently legal. Health concerns related to the processing of delta-8 THC products and their psychoactive effects remain understudied. ObjectiveThe goal of this study is to implement a novel topic modeling approach based on transformers, a state-of-the-art natural language processing architecture, to identify and describe emerging trends and topics of discussion about delta-8 THC from social media discourse, including potential symptoms and adverse health outcomes experienced by people using delta-8 THC products. MethodsPosts from January 2008 to December 2021 discussing delta-8 THC were isolated from cannabis-related drug forums on Reddit (Reddit Inc), a social media platform that hosts the largest web-based drug forums worldwide. Unsupervised topic modeling with state-of-the-art transformer-based models was used to cluster posts into topics and assign labels describing the kinds of issues being discussed with respect to delta-8 THC. Results were then validated by human subject matter experts. ResultsThere were 41,191 delta-8 THC posts identified and 81 topics isolated, the most prevalent being (1) discussion of specific brands or products, (2) comparison of delta-8 THC to other hemp-derived cannabinoids, and (3) safety warnings. About 5% (n=1220) of posts from the resulting topics included content discussing health-related symptoms such as anxiety, sleep disturbance, and breathing problems. Until 2020, Reddit posts contained fewer than 10 mentions of delta-8-THC for every 100,000 cannabis posts annually. However, in 2020, these rates increased by 13 times the 2019 rate (to 99.2 mentions per 100,000 cannabis posts) and continued to increase into 2021 (349.5 mentions per 100,000 cannabis posts). ConclusionsOur study provides insights into emerging public health concerns around delta-8 THC, a novel substance about which little is known. Furthermore, we demonstrate the use of transformer-based unsupervised learning approaches to derive intelligible topics from highly unstructured discussions of delta-8 THC, which may help improve the timeliness of identification of emerging health concerns related to new substances.

BackgroundMarijuana is the most commonly used federally illicit substance among reproductive-age women in the United States. Updated information on marijuana use in this population can inform clinical and public health interventions.MethodsData from the 2013-2019 National Survey on Drug Use and Health was used to report weighted prevalence estimates of marijuana use in the past month, past 2-12 months, and past year among women aged 18-44 years with self-reported pregnancy status. Bivariate analyses and general linear regression models with Poisson distribution using appropriate survey procedures identified factors associated with past-year marijuana use by pregnancy status.ResultsAmong pregnant women, 4.9% (95% confidence interval [CI]: 4.1-5.6) reported marijuana use in the past month, 10.4% (95% CI: 9.3-11.5) in the past 2-12 months, and 15.2% (95% CI: 13.9-16.6) in the past year. Among nonpregnant women, 11.8% (95% CI: 11.5-12.0) reported marijuana use in the past month, 7.8% (95% CI: 7.6-8.0) in the past 2-12 months, and 19.5% (95% CI: 19.2-19.9) in the past year. After adjusting for sociodemographic characteristics, past-year marijuana use was 2.3-5.1 times more likely among pregnant, and 2.1 to 4.6 times more likely among nonpregnant women who reported past-year tobacco smoking, alcohol use, or other illicit drug use compared to those reporting no substance use.ConclusionsPregnant and nonpregnant women reporting marijuana use, alone or with other substances, can benefit from substance use screening and treatment facilitation.
To understand trends in U.S. cannabis-involved emergency department (ED) visits (i.e., those for which cannabis use was documented in the chief complaint or a discharge diagnosis) among young persons aged <25 years during the COVID-19 pandemic, CDC used National Syndromic Surveillance Program data to examine changes in ED visits during 2019-2022. Mean weekly cannabis-involved ED visits among all young persons were higher during the COVID-19 pandemic in 2020, 2021, and 2022, compared with corresponding periods in 2019. Large increases in cannabis-involved ED visits throughout the COVID-19 pandemic compared with prepandemic surveillance periods in 2019 were identified among persons aged ≤10 years. ED visit rates among children and adolescents aged 11-14 years did not differ by sex until the first half of the 2020-21 school year (2020, weeks 37-53), when ED visit rates among females surpassed those among males. Improving clinicians' awareness of rising cannabis-involved ED visits might aid in early diagnosis of cannabis intoxication among young persons. Further, increasing adults' knowledge regarding safe cannabis storage practices, strengthening youths' coping and problem-solving skills through evidence-based prevention programs, and modifying cannabis packaging to decrease appeal to youths might help prevent intentional and unintentional cannabis use.
Background: Cannabis policies are rapidly changing in the United States, yet little is known about how this has affected cannabis-associated emergency department (ED) visits. Methods: We studied trends in cannabis-associated ED visits and identified differences by visit characteristics. Cannabis-associated ED visits from 2006 to 2018 were identified from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project's (HCUP) Nationwide Emergency Department Sample (NEDS). JoinPoint analysis was used to identify trends from 2006 to 2014, prior to medical coding changes in 2015, and Z-tests were used to compare annual rate changes from 2016 to 2018. Changes in rates from 2017 to 2018 were examined by visit characteristics. Results: From 2006-2014, the rate of cannabis-associated ED visits increased, on average, 12.1% annually (p < 0.05), from 12.3 to 34.7 visits per 100,000 population. The rate increased 17.3% from 2016 to 2017 (p < 0.05) and 11.1% from 2017 to 2018 (p < 0.05). From 2017-2018, rates of visits increased for both males (8.7%; p < 0.05) and females (15.9%; p < 0.05). Patients 0-14 years and 25 years and older had significant rate increases from 2017 to 2018 as did the Midwest region (36.8%; p < 0.05), the Northeast (9.2%; p < 0.05), and the South (4.5%; p < 0.05). Conclusions: Cannabis-associated ED visits are on the rise and subgroups are at increased risk. Some potential explanations for increases in cannabis-associated ED visits include increased availability of cannabis products, increased use, and diversity of products available in marketplaces. Strategies are needed to prevent youth initiation, limit potentially harmful use among adults, and ensure safe storage where cannabis use is legal.
Abstract Background Childhood poverty is known to be associated with poor health. For youth living in extreme poverty, community-based programs focused on youth development are one strategy to improve health and well-being outcomes. However, very few evaluations of the long-term effectiveness of youth development programs have been conducted. The aim of this study was to assess the long-term effectiveness of a positive youth development program (PYD), serving a segregated housing project with a history of community violence, to improve the health, education, and financial well-being of its alumni. Methods A quasi-experimental causal comparative study design was used to study the effectiveness of the Cabrini-Green Youth Program (CGYP). CGYP alumni (mean: 16.8 +/- 7.4 years after program participation) were surveyed. For comparison, participants from the same housing project who were eligible to participate in the CGYP but did not, were identified. Results In total, 246/417 (59%) eligible alumni were located. 221 alumni were available to be interviewed; 191/221 (86%) completed the interview survey along with 143 in the comparison group. Both groups self-identified as being Black, African American, and of Other race. Alumni were younger (34.6 vs. 38.1 years, p < .001), less likely to be female (62% vs. 74%, p =.03), and more likely to have been abused as a child (26% vs. 11%, p = .001). The majority in both groups reported to be in good to excellent health (83% of alumni vs. 74% of comparison group). After adjusting for comparison group differences, alumni were more likely to have completed college, 24% vs. 12% (adjusted odds ratio (aOR) 2.47, 95% CI, 1.25–4.86), and to end up with some money at the end of the month, 35% vs. 19% (aOR 2.16, 95% CI, 1.17, 3.97). Conclusions Participation in a PYD program starting at a young age may be associated with reduced poverty in adulthood, possibly aided by higher educational attainment and resultant increased income. PYD may be an effective strategy to supplement evidenced-based poverty reducing policies. This study of a voluntary, community-based PYD program is unique in its up to 33-year follow-up and an outcome assessment that measures more than knowledge change.
As policies legalizing adult cannabis use increase in the United States, understanding and characterizing the proportion of individuals consuming cannabis for medical and nonmedical purposes is important to inform targeted health education efforts. Data came from 7672 adults (> = 18 years) with past month cannabis use who responded to questions about reason for cannabis use on the 2018 Behavioral Risk Factor Surveillance System survey in 14 states. State and aggregated data were analyzed using weighted frequencies for descriptive analyses, and prevalence ratios were computed to identify demographic and substance use characteristics associated with medical only use or use for both medical and nonmedical reasons (vs. nonmedical use). Overall, 28.6% (95% CI: 26.7, 30.4) of adults who use cannabis reported using cannabis medically, 34.2% (95% CI: 32.3, 36.2) nonmedically, and 37.2% (95% CI: 35.2, 39.2) both medically and nonmedically. Characteristics associated with medical only use (compared with nonmedical only use) included being female; aged > 45 years; out of work, a homemaker, or unable to work; having daily or near daily cannabis use; having past month cigarette use; having no past month alcohol use; self-reporting poor health; and ever having been diagnosed with certain chronic diseases. Medical only use of cannabis is the least prevalent reason for use; use for both medical and nonmedical reasons is the most prevalent. Monitoring reasons for cannabis use can aid states in understanding differences between medical and nonmedical cannabis users, providing context to use patterns, and targeting health education messages to appropriate audiences.
