Mothers and fathers who use medical cannabis: A comparison of sociodemographic characteristics, cannabis use, and health

To assess prevalence rates and correlates of problematic use of prescription opioids and medicinal cannabis (MC) among patients receiving treatment for chronic pain. Cross-sectional study. Two leading pain clinics in Israel. Our sample included 888 individuals receiving treatment for chronic pain, of whom 99.4% received treatment with prescription opioids or MC. Problematic use of prescription opioids and MC was assessed using DSM-IV criteria, Portenoy’s Criteria (PC), and the Current Opioid Misuse Measure (COMM) questionnaire. Additional sociodemographic and clinical correlates of problematic use were also assessed. Among individuals treated with prescription opioids, prevalence of problematic use of opioids according to DSM-IV, PC, and COMM was 52.6%, 17.1%, and 28.7%, respectively. Among those treated with MC, prevalence of problematic use of cannabis according to DSM-IV and PC was 21.2% and 10.6%, respectively. Problematic use of opioids and cannabis was more common in individuals using medications for longer periods of time, reporting higher levels of depression and anxiety, and using alcohol or drugs. Problematic use of opioids was associated with higher self-reported levels of pain, and problematic use of cannabis was more common among individuals using larger amounts of MC. Problematic use of opioids is common among chronic pain patients treated with prescription opioids and is more prevalent than problematic use of cannabis among those receiving MC. Pain patients should be screened for risk factors for problematic use before initiating long-term treatment for pain-control.

Cannabis use patterns and motives: A comparison of younger, middle-aged, and older medical cannabis dispensary patients

Objectives: This study sought to extend research on the relation between depression symptoms and problematic cannabis use by evaluating the potential moderating role of perceived sleep quality among medical cannabis users. Methods: This employed a cross-sectional design. The sample consisted of 162 adults (mean age = 42.05 years, SD = 14.8; 22% female), with current recommendations from a doctor for medical cannabis, recruited from a medical cannabis dispensary. Results: Consistent with previous research, individuals with heightened depression symptoms had greater problematic cannabis use. In addition, perceived sleep quality moderated this relation, such that depression symptoms differentially related to problematic cannabis use as a function of perceived quality of sleep (ΔR2 = .03, p = .02). Participants with higher levels of depression and good perceived sleep quality had the greatest rates of problematic cannabis use. Conclusions: These results suggest that individuals with heightened depression may have higher rates of problematic cannabis use, in part, because of the beneficial effects of cannabis in terms of perceived sleep quality.

With the recent legalization of cannabis for medical purposes in many countries, there has been an increased number of individuals using such products. While there is considerable evidence indicating that cannabis may have therapeutic effects for a range of different conditions, concerns remain about the risk of developing cannabis use disorders for those at risk, or patients without appropriate clinical guidance. The aim of the present study was to determine the prevalence of problematic cannabis use in a cohort of cannabis users who consumed the drug for medical purposes and to identify potential risk factors. One hundred individuals who self-identified as using cannabis to improve their mental health were recruited from a community dispensary. Extensive details were collected about subjects' patterns of cannabis use and reasons for use. All subjects completed a structured clinical interview with the Mini-International Neuropsychiatric Interview, while information about perceived stress, depressive symptoms, and somatic symptoms were recorded with the Perceived Stress Scale-10, Beck Depression Inventory, and the Patient Health Questionnaire-15. Rates of problematic cannabis use were high, with 30% meeting the criteria. Only 10% of subjects reported medical cannabis use was recommended by their doctor. Significant risk factors for problematic use included earlier age of cannabis initiation, as well as self-reported use of cannabis products for depression. The prevalence of problematic cannabis use in the community dispensary was higher than expected. Specific risk factors for problematic cannabis use may represent important areas for future intervention to ensure safer consumption for medical purposes.

It is unknown how patterns of cannabis and other drug use changed among young adult cannabis users as they became, exited or stayed medical cannabis patients (MCPs) after California legalized cannabis for adult use in 2016. A cohort of 18–26 year-old cannabis users was recruited in Los Angeles in 2014–15 (64.8% male; 44.1% Hispanic/Latinx). Based on wave 1 (pre-legalization) and wave 4 (post-legalization) MCP status, four transition groups emerged: MCP, Into MCP, Out of MCP and NPU (non-patient user). Relationships between self-reported medical cannabis use, transition group membership, and cannabis/other drug use outcomes were examined. Changes in cannabis practices were consistent with changes in MCP status. Cannabis days, concentrate use, self-reported medical cannabis use and driving under influence of cannabis were highest among MCP, increased for Into MCP, and decreased for Out of MCP in wave 4. A majority of drug use outcomes decreased significantly by wave 4. Self-reported medical cannabis use was associated with more frequent cannabis use but less problematic cannabis and other drug use. Future studies should continue to monitor the impact of policies that legalize cannabis for medical or recreational use, and medical motivations for cannabis use on young adults’ cannabis and other drug use.

The relationship among depressive symptoms, urgency, and problematic alcohol and cannabis use in community adults

Background Low distress tolerance may result in greater vulnerability to problematic cannabis use. However, the role of the primary form of cannabis used has not been examined as a moderator of this association. While marijuana flower remains the preferred form of cannabis, the popularity of other forms of cannabis, including concentrates and edibles, is on the rise. Objectives We examined the association between distress tolerance and problematic cannabis use and whether the primary form of cannabis used moderates this relationship. Methods Participants were 695 (67.6% male) past-month cannabis users who completed an online survey. Multiple linear regressions assessed whether distress tolerance, the primary form of cannabis used, and their interaction were related to problematic cannabis use while controlling for demographic variables and past 30-day alcohol and cannabis use frequency. Results Lower tolerance for distress was associated with more problematic cannabis use. Endorsing concentrates as the primary form of cannabis used vs. marijuana flower was related to more problematic cannabis use while reporting edibles as the primary form of cannabis used vs. marijuana flower or concentrates was related to less problematic cannabis use. Individuals preferring marijuana flower or concentrates reported more problematic cannabis use at lower levels of distress tolerance. Conclusions Cannabis users exhibiting low distress tolerance or a preference for concentrates may be at greatest risk for experiencing negative consequences related to their cannabis use. Additionally, building tolerance for stressful situations, among both concentrates and marijuana flower users, may aid in minimizing problematic cannabis use.

Background: Despite evidence of the contribution of childhood trauma to the development of problematic cannabis use, its mediating pathways are largely unknown. Given the link between cannabis motives with trauma and problematic cannabis use, motives of use may represent a construct through which trauma impacts problematic cannabis use. Methods: A sample of 339 medical cannabis patient and non-patient young adult users from the Los Angeles area were sampled at baseline and one year later. The current study examined the impact of childhood trauma on problematic use through a variety of cannabis use motives. Results: Controlling for age, socioeconomic status, perceived stress, and baseline problematic use, endorsing the use of cannabis to cope with distress at baseline uniquely mediated the associations between different childhood trauma types (e.g., physical abuse, neglect, sexual trauma) and problematic use one year later. Experience of any childhood trauma was positively associated with coping motives, whereas emotional and physical abuse were positively associated with pain motives, and sexual abuse was positively associated with sleep motives. Using cannabis for coping and increasing attention/focus were also positively associated with higher problematic use, whereas using cannabis for sleep was inversely associated with problematic use one year later. Conclusions: The motives of coping with distress and inattention may represent intermediate constructs through which trauma leads to later problematic cannabis use. Results highlight the need to clarify the pathways between health and non-health-oriented motives and cannabis use over time.

Societal issues and policy implications related to the use of cannabinoids, cannabis, and cannabis-based medicines for pain management.

Cannabis use has been rising despite recognition of the negative consequences associated with heavy use. The severity of these consequences has been shown to differ across racial/ethnic groups, even when controlling for consumption levels. The present study conducted an item response theory (IRT) analysis of the Cannabis Use Disorders Identification Test (CUDIT) to better understand the patterns of problematic cannabis use and their relation with other substance use across ethnic groups in the Healthy Life in an Urban Setting (HELIUS) study. CUDIT responses from 1,960 cannabis-using African Surinamese, South-Asian Surinamese, Dutch, Moroccan, and Turkish ethnic origin participants were used to test for differential item functioning (DIF) within an IRT framework. After restricting the sample to men because of low frequency of use among women, several instances of uniform DIF were identified. Multiple-group IRT analysis yielded a harmonized cannabis use phenotype that was used to estimate ethnic group differences in problematic cannabis use and its relation to alcohol and tobacco co-use. These analyses suggested that cannabis users from certain ethnic minority groups experienced higher rates of problematic use than the majority group despite lower rates of cannabis use. Further, cannabis and tobacco use were positively related across groups, whereas only ethnic minority groups showed a positive relation between cannabis and alcohol use. These results demonstrate the importance of accounting for DIF when examining group differences in problematic cannabis use, and support prior evidence suggesting that certain ethnic minority groups may be more likely to experience problematic cannabis use and alcohol co-use relative to the majority group.

BackgroundAnger rumination is consistently associated with maladaptive psychopathological outcomes. However, there is a lack of research on the association between problematic cannabis use, cannabis use motives and anger rumination. Coping motives showed positive relationships with negative affectivity and emotion dysregulation, thus it might be possible that coping motives can mediate the effects of hostility and anger rumination on problematic cannabis use. AimsThe goal of the present study was to examine the mediating role of anger rumination and cannabis use motives on the relationship between hostility and problematic cannabis use. MethodsThe cross-sectional study used a convenience sample of 764 past year cannabis users with a risk for problematic cannabis use (Males: 70.42% [N = 538], Age: M = 29.24 [SD = 7.55]). Standardized and online questionnaires measured problematic use and motives of cannabis use, anger rumination and hostility. ResultsStructural equation modelling was used to test the proposed mediation model. Four significant indirect effects were identified in the mediation model. The positive effect of hostility on cannabis use problems was mediated (i) via coping motives, (ii) via anger rumination, (iii) via anger rumination and coping motives, and (iv) via anger rumination and conformity motives. ConclusionsThe present study was the first that examined the construct of anger rumination in the context of cannabis use. Possible risk mechanisms via anger rumination and cannabis use motives with negative reinforcement were suggested in the context of problematic cannabis use. Self-medication tendencies and emotion dysregulation processes might explain these pathways.

Young adults who engage in problematic cannabis use report lower work and interpersonal functioning yet are less likely to seek treatment, necessitating alternative methods for assessing and intervening on problematic cannabis use (e.g., mobile health applications to self-monitor drivers of cannabis use in daily life). However, previous work examining maintenance models of problematic cannabis use has primarily focused on modeling predictors of cannabis use as measured using static retrospective report rather than examining cannabis use as a series of interactions that unfold in everyday life. In this study, we analyzed ecological momentary assessment data (T = 3,230 observations) from 65 young adults who reported problematic cannabis use (Cannabis Use Disorders Identification Test-Revised: M = 10.38, SD = 4.35) and an interest in reducing their use. We used multilevel network analyses to model associations among biopsychosocial factors that aligned with social learning, self-medication, and experiential avoidance theories of substance use. Network models demonstrated consistent associations between socioenvironmental triggers and cannabis cravings, use, and intoxication that were nearly all clinically meaningful in size (bs > 0.10). Results indicated a statistically significant association between negative and positive affect with cannabis use and intoxication, respectively; however, these associations were not clinically meaningful in size. There were no clinically meaningful associations between coping strategies and cannabis use variables. Findings advance our understanding of cannabis use in everyday life, which is critical for refining more dynamic conceptualization of substance use and improving the precision of clinical assessments.

BackgroundThere has been an increased trend towards the legalisation of medicinal and recreational cannabis use worldwide. This has been controversial as the long-term effects of frequent cannabis use on the brain are still poorly understood.MethodsIn this study, we investigated whether the legal status of cannabis in the United States of America (USA) is associated with problematic cannabis use and impulsivity in 329 frequent cannabis users. The data were collected in 2015 and were analysed in 2017. Ethical approval for this study was obtained from Monash University in 2015.ResultsThe results indicated that participants’ problematic cannabis use and impulsivity was not different whether they resided in states where cannabis is legal for medical and/or recreational use or prohibited.LimitationsThe present study is a cross-sectional design, making it difficult to infer causality and establish whether cannabis use is a cause, consequence, or correlate of altered impulsivity.ConclusionOur study supports the notion that frequent cannabis use is associated with impulsive behaviours, whilst, conversely, we did not find an association between US state legalisation and problematic cannabis use or impulsivity.

Introduction: Since its legalization in 2018, cannabis use has substantially increased in Canada. This increased use is concerning, as one in every eleven cannabis users will go on to develop a cannabis use disorder. Further, problematic cannabis use is often related to the use of additional substances, particularly nicotine and alcohol, and there is evidence to suggest that the degree of harms associated with cannabis use increases when cannabis is used in conjunction with other substances. Additionally, personality is a known risk factor for problematic substance use, although to date problematic cannabis use has not been consistently linked to any specific personality trait. This study aimed to investigate the relationship between substance use, personality, and problematic cannabis use in a sample of cannabis using polysubstance users. Method: A sample of 521 polysubstance users (past 30-day users of cannabis, alcohol, and nicotine) completed an online survey measuring their substance use, dependence, and personality. Levels of substance specific dependence was measured using the Cannabis Use Disorder Identification Test – Revised, the Alcohol Use Disorders Identification Test, and the Fagerström Tests for Cigarette and E-cigarette Dependence, while personality was measured using the Substance Use Risk Profile Scale (SURPS). Results: Regression analyses showed that the top predictors for problematic cannabis use levels were levels of alcohol dependence, cigarette/e-cigarette dependence, impulsivity, and sensation seeking. Further analyses compared those who met the criteria for problematic cannabis use to those who did not; problematic cannabis users had significantly higher levels of alcohol and nicotine dependence, as well as higher levels of impulsivity and sensation seeking (all p’s <.001). Discussion: This study identified strong relationships of problematic cannabis use with problematic alcohol and cigarette/e-cigarette use, and with sensation seeking and impulsivity. The findings have implications for screening, intervention, and policy. For example, the strong relations of problematic cannabis use with problematic alcohol use speak to the inadvisability of the co-location of cannabis and alcohol sales, as is the case in several jurisdictions.

Little is known about trends in the treatment of problematic cannabis use in Canada. Trends in treatment utilization for problematic cannabis use were examined, as well as trends in the associated sociodemographic characteristics and frequency of cannabis use. This was a repeated cross-sectional study using data from the Drug and Alcohol Treatment Information System, capturing utilization of all community funded addiction treatment services in Ontario, Canada. Clients in treatment for their own problematic cannabis use from 2010/11 to 2015/16 were included. Two distinct groups were formed: clients with problematic cannabis use only (the cannabis-only group) and clients with problematic use of cannabis and other substances (the cannabis-plus group). Estimates of the number of clients in each of these groups and their cannabis use frequency (past 30 days) were characterized over time by new admissions and total caseload (new admissions plus carryovers). There were 152 984 admissions for 83 621 clients over the study period. The number of clients with new admissions in the cannabis-only group decreased from 2954 (95% confidence interval [CI] 2848-3062) in 2010/11 to 2342 (95% CI 2248-2439) in 2015/16. Similar downward trends were observed in the number of clients in the total caseload of this group. The number of clients with new admissions in the cannabis-plus group was stable, but the total caseload increased from 20 139 clients (95% CI 19 862-20 419) in 2011/12 to 21 816 (95% CI 21 527-22 107) in 2015/16. Proportions of daily cannabis use increased among clients in both groups. The number of clients in treatment for problematic cannabis use only decreased over the study period, but the frequency of cannabis use increased among clients in both groups. Given the potential reductions in treatment that is unnecessary from a clinical standpoint, alignment of treatment programming with disorder severity may be warranted.
