Abstract Although several studies have examined individual-level correlates of cannabis use in later life, there is scant evidence identifying heterogeneity among older users. Using data from Colorado, this study examines variability in lifespan patterns of cannabis use among individuals aged 60 years and older. Sample respondents reported cannabis use in the past year and frequency of use in four periods of adulthood. Analyses used a multi-way contingency table to identify mutually exclusive subgroups of cannabis users based on lifetime reports of use and linear probability models to identify predictors of group identity. Three subgroups of older...

In this nationwide analysis, we find that cannabis abuse is associated with higher perioperative thromboembolism and neurologic complications, respiratory complications, sepsis, length of stay, hospital charges, and rates of unfavorable discharge disposition. Study Design. Retrospective cohort analysis of a nationwide administrative database. Objective. The aim of this study was to analyze the association between cannabis abuse and serious adverse events following elective spine surgery. Summary of Background Data. Cannabis is the most popular illicit...

Abstract Background and Aims: Cannabis is a commonly used recreational drug in young adults. The worldwide prevalence in 18- to 25-year-olds is approximately 35%. Significant differences in cognitive performance have been reported previously for groups of cannabis users. However, the groups are often heterogeneous in terms of cannabis use. Here, we study daily cannabis users with a confirmed diagnosis of cannabis use disorder (CUD) to examine cognitive performance on measures of memory, executive function and risky decision-making. Methods: Forty young adult daily cannabis users with diagnosed CUD and 20 healthy controls matched for sex and premorbid intelligence quotient (IQ) were included. The neuropsychological battery...

Cannabis use is potentially associated with increased harms and varied effects on pain control. These have important implications to perioperative care. Methods We conducted a retrospective cohort study comparing surgical patients reporting cannabis use preoperatively to control patients with no cannabis exposure, in a 1:2 ratio. To control for confounding, we used a propensity score-matched analysis to assess the adjusted association between cannabis use and study outcomes. Our primary outcome was a composite of (1) respiratory arrest or cardiac arrest, (2) intensive care admission, (3) stroke,...

Abstract Cannabis legalization is expected to result in more frequent and compulsive use, potentially contributing to worsening psychosocial functioning among some cannabis users. This review evaluates associations between cannabis use and psychosocial functioning in recently published reports from prospective longitudinal studies and considers evidence for and against causation. Unlike previous reviews, studies of adolescents/emerging adults are considered separately from studies that followed adolescents well into adulthood, in part because of vast differences in cumulative cannabis exposure. Infrequent adolescent cannabis use is associated with poorer psychosocial functioning in some domains in emerging adulthood, whereas chronic, frequent adult use, regardless of adolescent-onset versus adult-onset, is associated...

Abstract Background: There are known sex differences in behavioral and clinical outcomes associated with drugs of abuse, including cannabis. However, little is known about how chronic cannabis use and sex interact to affect brain structure, particularly in regions with high cannabinoid receptor expression, such as the cerebellum, amygdala, and hippocampus. Based on behavioral data suggesting that females may be particularly vulnerable to the effects of chronic cannabis use, we hypothesized lower volumes in these regions in female cannabis users. We also hypothesized poorer sleep quality among female cannabis users, given recent findings highlighting the importance of sleep for many outcomes related to cannabis use disorder....

Abstract Purpose of Review The use of cannabis for the treatment of migraine has become an area of interest with the legalization of medical cannabis in the USA. Understanding the mechanisms of cannabinoids, available studies, and best clinical recommendations is crucial for headache providers to best serve patients. Recent Findings Patients utilizing medical cannabis for migraine have reported improvement in migraine profile and common comorbidities. Reduction in prescription medication is also common, especially opioids. Side effects exist, with the majority being mild. Not enough data is available for specific dose recommendations, but THC and CBD appear...

Motivational interviewing (MI) has shown efficacy in some substance use disorders. Therefore, a systematic review was conducted to assess the effectiveness of MI in CUD. Methods: Randomized controlled trials or open-label studies published until September 2019 from 3 different databases (Pubmed, Scopus, and PsycINFO) were included, following the PRISMA guidelines and a predetermined set of criteria for article selection. Meta-analyses were conducted. The end point was determined as month 3, and 4 outcomes were analysed (abstinence rates,...

The endocannabinoid system is a potential pharmacological target for pelvic pain as cannabinoid receptors are highly expressed in the uterus and other nonreproductive tissues. We hypothesize that cannabis use is common for self-management of CPP, and our primary objective was to determine the prevalence of cannabis use in this population. Materials and Methods: A cross-sectional survey of women with pelvic and perineal pain, dyspareunia, or endometriosis was performed between March and August 2019. Subjects were recruited in an outpatient gynecology office. An...

Veterans are disproportionately affected by conditions for which medical cannabis is often pursued, making an evidence-based perspective on risks versus benefits of high priority. The current review sought to examine the state of the evidence on the correlates and consequences of cannabis use among veterans. Using a comprehensive search strategy, 501 articles were identified and 86 studies met criteria for inclusion. The literature was predominated by cross-sectional studies (67%) of male veterans (71.4%–100% male) from the United States (93.0%). Three overarching themes emerged, comprising cannabis associations with other substance...
