RESUMEN
The use of Medicinal Cannabis (MC) for treating chronic pain is increasing, globally, yet the definition of problematic MC use remains unclear. Defining problematic use of cannabis in medical and non-medical contexts may be fundamentally different since individuals prescribed MC often experience physical dependence, which do not necessarily imply pathology. We aimed to conceptualize problematic use of MC and develop a brief questionnaire for identifying and quantifying problematic MC use. Content validation used a broad definition of problematic substance use, adapting and compiling an initial list of 36 items from various sources: (a) screening tools for assessing problematic prescription opioid medication use; (b) screening tools for problematic recreational cannabis use and (c) qualitative interviews with MC patients. 390 American self-identified chronic pain patients holding a MC card rated each item from the initial list on a 5-point frequency scale and filled out questionnaires assessing various clinical outcomes. Following initial item titration, a multi-group measurement invariance comparison strategy, using two external indicators: alcohol-related problems and depression, resulted a final eight-item list that met fit quality in a baseline model, presented excellent internal consistency reliability (α = 0.929), and significantly correlated with anxiety and low quality of life. Items in the final list related predominantly to negative consequences of MC use. Problematic use of MC is characterized by negative physiological, social, emotional and functional consequences. The final eight-item list was named the Medicinal Cannabis Negative Consequences Scale (MCNCS), emerging as a brief measure for problematic MC use and demonstrating preliminary reliability and validity, which could aid clinicians and researchers.

Importance: Research has shown evidence of increased substance use (ISU) in populations affected by mass terrorism; however, less is known regarding how psychosocial factors interact to estimate ISU following such events. Objective: To examine which factors are associated with reporting ISU, test whether psychological distress (PD) mediated the association between exposure to trauma and reporting ISU, and whether the mediation effect differed among those with prior mental health (MH) difficulties and those without. Design, Setting, and Participants: A partially representative cross-sectional survey of the adult Jewish population in Israel (aged 18-70 years) was conducted 4 weeks after October 7, 2023 (October 31 to November 5, 2023). A national Web panel using quotas based on national distributions was used. Randomly chosen adult Jewish members were invited to participate until a predetermined sample size was reached. Main Outcomes and Measures: The study measures included reporting ISU (outcome), PD (mediator), exposure to terror events and sociodemographic characteristics (variables), and prior MH difficulties (moderator). Hypotheses regarding outcome and variables were formulated before data collection. Results: A total of 7000 invitations were distributed, 2679 individuals consented, 1432 were excluded owing to quota limits, 74 failed attention tests, and 205 opted out, resulting in 968 participants (490 women [50.6%]; mean [SD] age, 41.5 [14.6] years). Hierarchical regression analysis revealed that participants were significantly more likely to report ISU if they had experienced direct exposure (odds ratio [OR], 5.75; 95% CI, 2.53 to 13.05), indirect exposure (OR, 1.84; 95% CI, 1.27 to 2.67), media exposure (OR, 1.22; 95% CI, 1.09 to 1.36), PD (OR, 1.80; 95% CI, 1.44 to 2.25), or previous MH difficulties (OR, 2.76; 95% CI, 1.86 to 4.09). PD partially mediated the association between indirect exposure (b = 0.20; 95% CI, 0.11 to 0.31) and media exposure (b = 0.14; 95% CI, 0.10 to 0.19) and reporting ISU. No evidence was found to support previous MH difficulties as a moderator of these indirect effects (indirect exposure, b = -0.003; 95% CI, -0.28 to 0.28; media exposure, b = 0.01; 95% CI, -0.06 to 0.08). Conclusions and Relevance: This study contributes to the research on the association of mass terrorism with ISU while shedding important light on the role it may play in the self-medication of PD following exposure, even in those who might have no previous MH difficulties. These insights are crucial for planning essential health services and preventive measures.

BACKGROUND: Substance use is a leading cause of preventable morbidity and mortality worldwide. Population-wide screening for problematic substance use in primary health care may mitigate the serious health and socio-economic consequences of such use, but the standard Alcohol, Smoking and Substance Involvement Screening Test (ASSIST 3.1) may be too long for wide-scale screening. How well validated shorter versions (ASSIST-Lite, ASSIST-FC) perform in identifying those with ASSIST 3.1 problematic use in different settings is unclear. METHODS: General population Jewish adults in Israel (N = 2,474) responded to an online survey that included the ASSIST 3.1 and sociodemographics. Across substances (alcohol, tobacco, cannabis, sedatives, prescription stimulants, prescription painkillers), receiver operator characteristic curve analysis determined that ASSIST-FC scores performed better than ASSIST-Lite at identifying those with problematic use, and evaluated differential ASSIST-FC performance by gender or age. Test characteristics and agreement were evaluated for binary ASSIST-FC versions, with ASSIST 3.1 problematic use as the gold standard. RESULTS: ASSIST-FC scores showed high ability to identify ASSIST 3.1 problematic use, with minimal differences by gender or age. Binary ASSIST-FC (most substances: threshold 3+; alcohol: 5+) showed high specificity and positive predictive value, acceptable sensitivity, and good agreement. CONCLUSIONS: The ASSIST-FC, which assesses frequency of use and other's concerns about use, appears useful for very brief screening in primary care to identify patients who may benefit from intervention. Early identification of those at-risk may prevent more severe consequences and ultimately decrease the significant costs of problematic substance use on the individual and population level.

AIMS AND OBJECTIVES: In this study, we systematically reviewed qualitative studies concerning patients' experience with medicinal cannabis (MC) use, to gain insight into the negative effects of MC. BACKGROUND: Over the past decades, the use of MC for therapeutic purposes has increased. However, there is conflicting and insufficient data on possible negative physiological and psychological effects of MC treatment. DESIGN: A systematic review was conducted and the PRISMA guidelines were adopted. Literature searches were conducted using PubMed, PsycINFO and EMBASE. Critical Appraisal Skills Programme (CASP) qualitative checklist used to assess risk of bias in the included studies. METHODS: We included studies focusing on conventional medical treatment using cannabis-based products, approved by a physician for a particular health issue. RESULTS: Of the 1230 articles identified in the initial search, eight articles were included in the review. Following the compilation of themes in the eligible studies, six themes were identified: (1) MC approval; (2) administrative barriers; (3) social perception; (4) MC misuse/widespread effect; (5) adverse effects; and (6) dependence or addiction. These were grouped into two meta-themes: (1) administrative and social aspects of MC use; and (2) experiences of the effects of medicinal cannabis. CONCLUSIONS: Our findings call for specific attention to unique consequences associated with MC use. Further research is needed in order to assess the degree to which negative experiences associated with MC use may affect various aspects of patients' medical condition. RELEVANCE TO CLINICAL PRACTICE: Describing the complex experience of MC treatment and its spectrum of consequences for patients may enable physicians, therapists and researchers to provide more attentive and accurate MC treatment to their patients. PATIENT OR PUBLIC CONTRIBUTION: In this review, patients' narratives were explored, yet the research methods did not directly involve patients or the public.

AIMS AND OBJECTIVES: To explore the ways in which stigma is experienced, and what strategies are used to manage stigma among patients using medical cannabis to ease suffering from chronic pain. BACKGROUND: Various jurisdictions have legalised medical cannabis in recent decades. Despite increasing prevalence and more liberal attitudes towards medical cannabis, it is possible that patients who use medical cannabis experience stigma. DESIGN: A phenomenological qualitative study. METHODS: Fifteen patients living with chronic pain and licensed by the Israeli Ministry of Health to use medical cannabis to treat pain symptoms for at least 1 year participated in semi-structured interviews. Transcribed data were analysed using thematic analysis to identify themes related to stigma. The manuscript is in correspondence to SRQR EQUATOR checklist. RESULTS: Expressions of stigma were more related to 'felt' than 'enacted' stigma. Stigma related to decisions to delay onset of medical cannabis treatment and the ways in which participants managed medical cannabis use during their everyday lives. Participants dissociated themselves from recreational cannabis users, by presenting themselves as responsible normative individuals and engaging in a form of normalisation known as 'normification', emphasising their own discrete and controlled medical cannabis use and cannabis' benefits. CONCLUSIONS: Patients experienced 'felt' stigma which had consequences for their self-presentations and medical cannabis use. This suggests that medical cannabis is not normalised in Israel and interventions may be needed to handle stigma related to medical cannabis. RELEVANCE TO CLINICAL PRACTICE: The findings emphasise the effects of 'felt' stigma on patients. Aiming to increase the effectiveness of medical cannabis treatment and reducing harms, we suggest that particular focus should be placed on managing stigma at the intrapersonal level. In addition, there may be a need to address stigma at the societal level including social interactions with friends, family and medical personnel.

Psychedelics were used in the treatment of psychiatric conditions prior to their prohibition in the late 1960s. In the past three decades, there is a revived research interest in the therapeutic potential of psychedelic drugs with expected FDA approvals for treatment of various conditions. Given the exponential scientific growth of this field, we sought to characterize, analyze, and visualize trends in its top-cited articles. Bibliometric analyses are quantitative approaches to characterize a scientific field, including evaluation of the impact of academic literature. The bibliometric analysis and visualizations were conducted with R-tools for comprehensive science mapping. The top-cited 100 articles were cited between 82 and 668 times (median 125; mean 158). Fifty-four percent of the T100 articles were produced in the past decade (2010-2020). Network and author impact analysis highlighted key figures and primary collaboration networks within the top 100 publications. UK, USA, Switzerland, Spain, and Brazil lead the field. Results are discussed in terms of research growth, access, diversity, and the distribution of knowledge and experience in the field. These aggregated data and insights on the second wave of psychedelic research facilitate research evaluation, data-driven funding policies, and a practical map for researchers and clinicians entering the field.

Bipolar disorder (BD) is a serious chronic mood disorder associated with high rates of co-occurring substance use disorders. Shared psychotic disorder (SPD) is a rare clinical phenomenon and has been reported in only a few cases of individuals diagnosed with BD. Furthermore, reports concerning SPD being induced by substance use or withdrawal are lacking. We report the case of a married couple endorsing simultaneous psychosis, a form of SPD. The primary case (the wife) had a diagnosis of BD, without any history of psychotic episodes before the current episode, while the secondary case (the husband) had a diagnosis of posttraumatic stress disorder. Both individuals were misusing prescribed synthetic opioids, and their psychosis was most likely induced by a withdrawal state. Cases of SPD involving patients with BD have rarely been reported. Considering the high rates of dual diagnoses among patients with BD, clinicians should be aware of the risk of substance-induced psychosis among these individuals and the manifestation of these psychotic episodes. This case report strengthens previous reports suggesting that SPD is a clinical entity that can occur not only in situations where the primary case involves an individual diagnosed with delusional disorder or schizophrenia, but that it may also occur when the primary case has a diagnosis of BD.

AIM: To quantify the healthcare costs associated with opioid use disorder among members in a public healthcare system and compare them with healthcare costs in the general population. DESIGN: Retrospective cohort study. SETTING: Inpatient and outpatient care settings of Israel's largest public healthcare provider (that covers 4.7 million members). PARTICIPANTS: Participants included 1173 members who had a diagnosis of opioid use disorder in the years between 2013 and 2018. Each patient was matched with 10 controls based on age and sex. MEASUREMENTS: The main outcome was monthly healthcare costs. FINDINGS: The mean monthly healthcare cost of members with opioid use disorder was $1102 compared with $211 among controls (5.2-fold difference; 95% CI, 4.6-6.0). After excluding members with heroin related diagnoses before the index date (to focus on prescription opioids), this healthcare cost ratio did not substantially change (4.6-fold; 95% CI, 3.9-5.4). Members with opioid use disorder under the age of 65 years had a cost difference of 6.1-fold (95% CI, 5.2-7.1), whereas those 65 years and older experienced cost difference of 3.4-fold (95% CI, 2.6-4.5), compared with controls. The category with the highest cost for members with opioid use disorder was inpatient services, which was 8.7-fold (95%CI, 7.2-10.4) greater than among controls. CONCLUSIONS: Healthcare costs among individuals with opioid use disorder in Israel's public health system are substantially higher than among controls, at least partially attributable to prescription opioid use disorder. Differences are greater among individuals under 65 years.

Objective: Classic psychedelics (LSD, psilocybin, and peyote/mescaline) have been used to support addiction treatment in a variety of contexts ranging from ceremonial use to clinical trials. The aim of this study was to test the hypothesis that past naturalistic use of classic psychedelics would be associated with decreased prevalence of substance use disorder, when controlling for known confounders. Methods: This cross-sectional study used 2017 NSDUH survey data to evaluate the association between past use of the classic psychedelics LSD, psilocybin and peyote/mescaline and past year substance dependence or abuse. We calculated adjusted odds ratios by multivariate logistic regression, controlling for a range of sociodemographic variables, use of non-psychedelic illicit drugs and mental health related variables. Results: A total of 56,276 participants were included in this study. Past use of LSD and psilocybin were associated with increased odds of substance dependence or abuse compared to those who had never used psychedelics before, and this was more likely for those who had used LSD more recently. However, prior use of peyote or mescaline was associated with lower odds of past year substance dependence or abuse compared to people who had never used psychedelics before (aOR = 0.68, p < 0.001). Past use of classic psychedelics was not associated with nicotine dependence. Conclusion: Past use of peyote/mescaline was associated with decreased odds of substance use disorder compared to people who had never used psychedelics before, while past use of LSD or psilocybin was not. It remains unclear whether this difference is due to pharmacological differences between these compounds or simply due to the context in which peyote/mescaline are traditionally taken. Future research should investigate why naturalistic use of different psychedelics is associated with different substance use disorder effects.
RESUMEN
This study explored whether personal attitudes toward drug users are associated with professional approaches and whether the association between personal and professional attitudes varies across different mental health professions. Participants (N = 347) included medical (psychiatrists and psychiatric nurses) and other (clinical psychologists and social workers) mental health professions from all 13 mental health centers in Israel. They completed questionnaires aimed to assess familiarity with medical usage of hallucinogenic drugs, personal attitudes toward recreational drug users and willingness to use five hallucinogens in research of clinical practice. Hypotheses were tested using multiple-group structural equation modeling (SEM). Psychiatrists reported the highest levels of familiarity with and willingness to use all types of hallucinogenic drugs, as compared to other mental health professionals. Psychiatrists held the strongest belief in the potential utility of hallucinogenic drugs; yet, their personal attitudes toward drug users affected negatively their willingness to try hallucinogenic drugs in clinical practice. This was the only significant association that was found. Future research and treatment programs should address the topic of hallucinogenic drug therapy, and specifically the need to separate between individual beliefs and professional clinical decision-making.

The Internet Addiction Test (IAT) (Young, 1998) is one of the most utilized diagnostic instruments to evaluate internet addiction. Despite the wide use of IAT in research and clinical settings, there is lack of an empirical validation of this scale among a largescale adult population. The present study aimed to: (1) investigate the psychometric properties of a Hebrew version of the IAT among large-scale Israeli adult sample. (2) Assess the socio-demographic characteristics of individuals who suffer from IA. (3) Assess the co-morbidity of IA in relation to substance and behavioral addictions. A cross sectional study was conducted, by constructing a representative sample (N = 4035) of the Jewish adult (18-70 y/o, M = 40.5, SD = 14.5) population in Israel. Participants responded an online survey, that measured IAT, socio-demographic characteristics, substance and behavioral addictions. Results showed that two-factor model (Emotional and Cognitive Preoccupation with the Internet and Loss of Control and Interference with Daily Life) has good psychometric properties and fits the data well. Young age, not being married (Risk Ratio [RR] = 1.98, 95% CI [1.51-2.63]), and having a low socio-economic status (RR = 1.41, 95% CI [1.05-1.90]) were found to be associated with IA. Drug (RR = 4.50, 95% CI [2.89-7.01]) and alcohol (RR = 3.54, 95% CI [1.50-5.42]) use disorders were associated with IA. High co-morbidity between behavioral addictions and IA was also found (RR = 15.24, 95% CI [11.17-20.78]). Overall, results show that the Hebrew version of the IAT is a valid and reliable instrument, and provide a comprehensive picture of IA prevalence and profile in adult Israeli sample.

BACKGROUND: In recent decades, the US religious landscape has undergone considerable change such as a decline in religious service attendance. These changes may indicate that religious social support structures have deteriorated, possibly leading to a decrease in strengths of associations with substance use. Considering this, and given limitations of past studies (e.g., limited control for potential confounders), large-scale general population studies are needed to reexamine associations between religiosity domains and substance use. METHODS: This cross-sectional study used data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III (N = 36,309). In unadjusted and adjusted models, controlling for religiosity domains and other covariates, we examined associations between three religiosity domains (importance of religiosity/spirituality, service attendance, and religious affiliation) and DSM-5 SUD. Focusing on service attendance, we also examined associations with other substance use-related outcomes. RESULTS: Among religiosity domains, only frequency of service attendance was associated with SUD across most substances. Frequent service attendees had lower odds of alcohol use disorder (adjusted OR [aOR] = 0.4, 95 % CI 0.33,0.51), tobacco use disorder (aOR = 0.3, 95 % CI 0.22,0.33) and cannabis use disorder (aOR = 0.4, 95 % CI 0.24,0.68), compared to non-service attendees. For alcohol and tobacco, the protective effect of frequent service attendance was more robust for SUD than for respective substance use. CONCLUSIONS: Despite decreasing rates of religious belief and practice in the US, service attendance independently lowered the odds of substance use and SUD across multiple substances. Results may inform religious leaders and clinicians about the value of utilizing religious social support structures in the prevention and treatment of substance use and SUD.

Exposure to trauma is considered a risk factor for the development of addictive disorders. Currently, there is a knowledge gap concerning specific links between types and levels of exposure to traumatic events and addiction.In this study we explored the associations between interpersonal trauma and risk of addictive behaviors, stratified by type of trauma (physical, weapon, sexual assault, and combat) and level of exposure (direct/indirect), focusing on a wide range of substances and behaviors. Data from an online representative sample of 4025 respondents were collected, including the Life Events Checklist (LEC-5), substance use disorders and behavioral addictions metrics, and sociodemographic data. Substantial differences were found between specific types of trauma and risk of addiction. Among those exposed to sexual assault, the risk of alcohol use disorder was found to 15.4%, 95%CI[14.4-16.4%], compared to 12.1%,95%CI[11.3-12.8] among those exposed to combat-related trauma. Both direct and indirect exposure to trauma were found to be significantly related with risk of addiction. While direct exposure was most highly associated with addictions across several types of trauma, in the case of combat-related trauma, indirect exposure was more highly associated with alcohol and pornography addiction (14.5%,95%CI[13.2-15.8%] and 10.0%, 95%CI[6.3-15.0%], respectively) compared to direct exposure (10.7%,95%CI[9.9-11.6%] and 7.4%, 95%CI[4.7-11.6%], respectively). Our findings emphasize the strong association between all types of trauma and the risk of several specific substance and behavioral addictions. Specifically, the role of indirect exposure to trauma is highlighted.

INTRODUCTION: Substance use disorders (SUDs) are a leading cause of morbidity and mortality worldwide, having a profound and global impact on health, well-being, safety, and productivity. Although traditionally the prevalence of SUDs in Israel has been estimated to be lower than those in high-income countries, estimates and characteristics of individuals with SUDs in the past decade are lacking. In this work, we explored the prevalence of SUDs among the adult Jewish population in Israel, per different classes of substances across sex, age group, and other sociodemographic factors. METHODS: Data from an online representative sample of 4,025 respondents were collected, including the alcohol, smoking, and substance involvement screening test (ASSIST) metric and sociodemographic data. RESULTS: We found that the most common SUDs were alcohol (10.5% [9.5-11.4]), cannabis (9.0% [8.2-9.9]), and sedative (3.6% [3.0-4.2]) use disorders. Alcohol-cannabis (3.2% [2.7-3.7]) and alcohol-sedative (1.04% [0.7-1.35]) were the most prevalent co-occurring SUDs. Among those with cannabis use disorder, the prevalence of alcohol use disorder was found to be 35.3% [30.4-40.2]. The estimated risk for alcohol use disorder was found to be inversely proportional to age, cannabis use disorder increased, peaked, and decreased with age, and that of sedative use disorder increased with age, particularly among women. While older individuals (in the 51-60 years of age group) were at lower risk (OR = 0.5 [0.3, 0.8]) compared to those <20 years of age for alcohol use disorder, they were at increased risk for sedative use disorder (OR = 3.1 [1.2, 9.7]). CONCLUSIONS: These findings represent substantially higher rates of SUDs in Israel than those previously reported and should affect resources allocated to addiction prevention and treatment. Further research on the role of gender, age, culture, and ethnicity in the propensity to develop SUDs is necessary for the development of more focused preventive and intervention measures. Focusing on non-Jewish populations in Israel and broadening the scope to include behavioral addictions should be addressed in future studies.

BACKGROUND: Self-substitution is the conscious switch from one drug to another for reasons such as price, availability, desired effect, or perceived benefit of the substitute drug. Purpose/Objectives: This study aimed to describe drug use patterns and motivations associated with substitution. We examined correlates of lifetime substitution among individuals with substance use disorder. Methods: A cross-sectional study of 771 treatment-enrolled individuals. We used self-report for determining the lifetime prevalence, correlates, and motivations for substitution. Results: Of the 771 respondents, 570 (73.9%) reported ever substituting their preferred substance. The main incentives for substitution were availability (23.7%) and curiosity (20.2%). Among heroin or cannabis preferers, improved effects or less adverse effects of the substitute drug, self-medication, and managing withdrawal symptoms were significant substitution incentives. Increased odds for substitution were observed for past 12 months use of cannabis (OR = 1.51, CI = 1.06-4.52), prescription opioids (OR = 2.86, CI = 1.81-4.52), novel psychoactive substances (OR = 2.68, CI = 1.64-4.36), and repeated admission (OR = 1.50, CI = 1.05-2.14). Older age at onset-of-use was negatively associated with substitution (OR = 0.95, CI = 0.93-0.98). Conclusions: Self-substitution of one substance for another is a highly prevalent behavior among treatment-enrolled patients with substance use disorder. Clinicians caring for substance use disorder patients should be aware of substitution patterns involving the use of highly potent substances, which constitutes a risk to patients. Results underscore the benefit of substitution patterns analyses, as they reveal important information on the characteristics of persons who use drugs and their motivations.

BACKGROUND: The use of medical marijuana (MM) for the treatment of chronic pain is rapidly growing in the United States and Europe; however there is concern regarding the specificity of its therapeutic effects and the motivation underlying its use. While research indicates that among chronic pain prescribed opioids, depression has been associated with increased opioid dosage (regardless of pain levels), the extent to which depression and pain each contribute to MM dose among chronic pain patients is yet unknown. METHODS: This cross-sectional study included 209 chronic pain patients prescribed smoked MM, in flower or other plant form, with no concurrent opioid treatment. Ordinal regression analyses were performed in order to explore the unique contribution of mean pain level (1-10 scale), depression severity (measured by the Patient Health Questionnaire (PHQ-9)) and anxiety severity (measured by the Generalized Anxiety Disorder scale (GAD-7)) to doses of MM, while taking into account additional sociodemographic and clinical factors. RESULTS: Individuals with mild depression and those with moderate to severe depression were at significantly increased odds for using higher doses of MM in grams per month(Adjusted Odds Ratio(AOR) = 2.06,95% Confidence Interval(CI) = 1.05-4.01, and AOR = 5.95,95% CI = 1.97-17.98, respectively) compared to those without depression. In addition, individuals with mild depression were at significantly increased odds for smoking more MM joints daily(AOR = 2.07, 95% CI = 1.01-4.23) compared to individuals without depression. Mean levels of pain or anxiety severity were not significantly associated with either dose measures. CONCLUSIONS: Depression and MM dose are highly correlated and should be concurrently addressed during chronic pain treatment.

INTRODUCTION AND AIMS: It has been previously reported that more than 34% of individuals who use cannabis may qualify for a diagnosis of DSM-IV cannabis abuse or dependence throughout their lifetime. The introduction of the DSM-5 cannabis use disorder (CUD) diagnostic criteria reflects several intrinsic changes in the perception of substance use disorders. However, little is known about the probability of transition from cannabis use to CUD over time nor about the sociodemographic and clinical correlates associated with this transition. DESIGN AND METHODS: Participants were individuals ≥18 years interviewed in the National Epidemiologic Survey on Alcohol and Related Conditions-III in 2012-2013. Measurements included univariable and multivariable discrete-time survival analyses performed to examine the association between previously reported cannabis dependence predictors and the hazards of transitioning from cannabis use to CUD. Survival plots assessed the probability of transition from cannabis use to CUD over time since age of first use and differences in probability between predictor levels. RESULTS: Among lifetime cannabis users (N = 11 272), lifetime probability of transition to CUD was approximately 27%. A higher probability of transition from cannabis use to CUD was observed in the following: men, participants belonging to an ethnic minority group, early-onset cannabis users and individuals who reported experiencing three or more childhood adverse events. DISCUSSION AND CONCLUSIONS: This is the first study to explore transition from cannabis use to the DSM-5 CUD diagnosis. The current study identified specific predictors of this transition, which may assist in targeting at-risk populations.

PURPOSE OF REVIEW: Cannabis is widely used worldwide and cannabis use disorders are highly comorbid with anxiety disorders. In this review, we consider the recent literature on the effects of cannabis on the incidence, course, and treatment outcomes of anxiety disorders. RECENT FINDINGS: Although cannabis use is mostly found to be associated with increased incidence of anxiety disorders, these findings are generally not sustained in adjusted analyses controlling for multiple confounders. There are some equivocal data suggesting higher risk for anxiety disorders among heavy cannabis users. The scarce data available indicates no clear effect of cannabis use on the course and treatment outcomes of anxiety disorders. SUMMARY: Further research is needed focusing on trajectories of cannabis-induced acute anxiety, effects of cannabis use on treatment outcomes in anxiety disorders, and common genetic factors. Future epidemiological studies should utilize more precise measures of cannabis use and address several confounding factors which may affect the association between cannabis use and anxiety disorders.
