Resumo:BACKGROUND: Maternal cannabis use in pregnancy is linked with long-term adverse behavioral outcomes in offspring. Epigenetic processes established in utero that affect dopaminergic (reward) signaling may mediate risks. Associations between cannabis use and offspring DNA methylation have not been investigated; however, maternal tobacco smoking in pregnancy is associated with distinct patterns of DNA methylation at birth and beyond. OBJECTIVES: To determine whether maternal cannabis use is associated with methylation of the dopamine receptor gene DRD4 promoter in infants. METHODS: Mothers in the Triple B study provided detailed information on drug use in each trimester of pregnancy. Buccal swabs were collected from neonates at 8 weeks (n = 804, 51.7% male, and 48.3% female). DRD4 promoter DNA methylation was measured using SEQUENOM MassARRAY. RESULTS: Fifty-seven of the women in the study reported drug use during pregnancy, of whom 44 used cannabis. Of 19 cytosine-phosphate-guanine dinucleotides (CpG) units tested in DRD4, gestational cannabis use was associated with offspring methylation at 1 CpG unit in multivariate models (ß + 1.48, CI: 0.02 to 2.93, and p = 0.047). At another site there was weak evidence that both cannabis and other drug use were independently associated with increased methylation, while the association with tobacco was in the reverse direction (cannabis use ß + 0.67, CI: -0.12 to 1.46, and p = 0.09; other drug use ß + 1.11, CI: 0.17 to 2.05, and p = 0.02; tobacco use ß -0.41, CI: -0.85 to 0.03, and p = 0.07). None of the associations would remain significant after correction for multiple testing. CONCLUSION: There is no strong evidence that maternal cannabis use in pregnancy is associated with offspring DRD4 methylation.

Resumo:BACKGROUND: Support for the legalization of recreational marijuana continues to increase across the United States and globally. In 2016, recreational marijuana was legalized in the most populous US state of California, as well as three other states. The primary aim of this study was to examine trends in support for recreational marijuana legalization in Washington, a state which has had legal recreational marijuana for almost four years, using data collected over the four years post-legalization. A secondary aim was to examine trends in support for the cultivation of marijuana for personal use. METHODS: Data come from geographically representative general population samples of adult (aged 18 and over) Washington residents collected over five timepoints (every six months) between January 2014 and April 2016 (N=4101). Random Digit Dial was used for recruitment. Statistical analyses involved bivariate comparisons of proportions across timepoints and subgroups (defined by age, gender, and marijuana user status), and multivariable logistic regression controlling for timepoint (time) to formally test for trend while controlling for demographic and substance use covariates. All analyses adjusted for probability of selection. RESULTS: Support for legalization in Washington has significantly increased: support was 64.0% (95% CI: 61.2%-67.8%) at timepoint 1 and 77.9% (95% CI: 73.2%-81.9%) at timepoint 5. With each six months' passing, support increased 19% on average. We found no statistically significant change in support for home-growing. CONCLUSIONS: Support for marijuana legalization has continued to significantly increase in a state that has experienced the policy change for almost four years.

Resumo:BACKGROUND: Given increasing numbers of older-adult marijuana users, this study examined the association of marijuana use and marijuana use disorder with life stressors and perceived social support in the 50+ age group. METHODS: Data came from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (N=14,715 respondents aged 50+). Life stressors were measured with 12 items related to interpersonal, legal, and financial problems and being a crime victim. Perceived social support was measured with the 12-item Interpersonal Support Evaluation List. Using principal component analysis (PCA), we identified four components of life stressors. Linear regression analyses was used to test associations of past-year marijuana use and use disorder with PCA scores of each component and perceived social support. RESULTS: Of the 50+ age group, 3.89% were past-year marijuana users and 0.68% had marijuana use disorder. Marijuana users, especially those with marijuana use disorder (17.54% of past-year users), had high rates of mental and other substance use disorders. Controlling for other potential risk factors for stress, including health status and mental and other substance use disorders, marijuana use and use disorder were still significantly associated with more life stressors and lower perceived social support, possibly from low levels of social integration. CONCLUSIONS: A substantial proportion of older-adult marijuana users need help with mental health and substance use problems. Further examination of older marijuana users' life stressors and social support networks may aid in developing more systematic intervention strategies to address needs and reduce marijuana use.

Resumo:PURPOSE: To examine the prevalence and correlates of vaporization (i.e., "vaping") as a route of cannabis administration in a sample of medical cannabis patients. PROCEDURES: Adults ages 21 and older (N=1485M age=45.1) who were seeking medical cannabis certification (either for the first time or as a renewal) at medical cannabis clinics in southern Michigan completed a screening assessment. Participants completed measures of route of cannabis administration, cannabis use, alcohol and other substance use. FINDINGS: An estimated 39% (n=511) of the sample reported past-month cannabis vaping, but vaping as the sole route of cannabis administration was rare. Specifically, only 30 participants (2.3% of the full sample and 5.9% of those who reported any vaping) indicated vaping as the sole route of cannabis administration. The majority (87.3%) of those who reported vaping also reported smoking (combustion) as a route of cannabis administration. Being younger than age 44, having more than a high school education, engaging in nonmedical stimulant use, being a returning medical cannabis patient, and greater frequency of cannabis use were associated with higher odds of vaping at the bivariate level and with all variables considered simultaneously. CONCLUSIONS: Vaping appears to be relatively common among medical cannabis patients, but is seldom used as the sole route of cannabis administration. RESULTS: highlight the importance of monitoring trends in vaping and other substance use behaviors in this population and underscore the need for longitudinal research into the motives, correlates, and consequences of cannabis vaping in medical cannabis patients.

Título:Medical Cannabinoids in Children and Adolescents: A Systematic Review.

ISSN:1098-4275
País de publicação:United States
Idioma:eng
Resumo:CONTEXT: Legalization of medical marijuana in many states has led to a widening gap between the accessibility and the evidence for cannabinoids as a medical treatment. OBJECTIVE: To systematically review published reports to identify the evidence base of cannabinoids as a medical treatment in children and adolescents. DATA SOURCES: Based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a search of PubMed, Medline, and the Cumulative Index to Nursing and Allied Health Literature databases was conducted in May 2017. STUDY SELECTION: Searching identified 2743 citations, and 103 full texts were reviewed. DATA EXTRACTION: Searching identified 21 articles that met inclusion criteria, including 22 studies with a total sample of 795 participants. Five randomized controlled trials, 5 retrospective chart reviews, 5 case reports, 4 open-label trials, 2 parent surveys, and 1 case series were identified. RESULTS: Evidence for benefit was strongest for chemotherapy-induced nausea and vomiting, with increasing evidence of benefit for epilepsy. At this time, there is insufficient evidence to support use for spasticity, neuropathic pain, posttraumatic stress disorder, and Tourette syndrome. LIMITATIONS: The methodological quality of studies varied, with the majority of studies lacking control groups, limited by small sample size, and not designed to test for the statistical significance of outcome measures. Studies were heterogeneous in the cannabinoid composition and dosage and lacked long-term follow-up to identify potential adverse effects. CONCLUSIONS: Additional research is needed to evaluate the potential role of medical cannabinoids in children and adolescents, especially given increasing accessibility from state legalization and potential psychiatric and neurocognitive adverse effects identified from studies of recreational cannabis use.

Resumo:BACKGROUND & AIMS: The impact of marijuana on nonalcoholic fatty liver disease (NAFLD) is largely unknown. We studied the association between marijuana and NAFLD utilizing cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) from 2005-2014 and NHANES III (1988-1994). METHODS: Suspected NAFLD was diagnosed if serum alanine aminotransferase (ALT) was > 30 IU/L for men and > 19 IU/L for women in the absence of other liver diseases (NHANES 2005-2014). In NHANES III cohort, NAFLD was defined based on ultrasonography. RESULTS: Of the 14,080 (NHANES 2005-2014) and 8,286 (NHANES III) participants, prevalence of suspected NAFLD and ultrasonographically-diagnosed NAFLD were inversely associated with marijuana use (p < 0.001). Compared to marijuana-naïve participants, marijuana users were less likely to have suspected NAFLD (odds ratio [OR]: 0.90, 95% confidence interval [CI]: 0.82-0.99 for past user; OR: 0.68, 95% CI: 0.58-0.80 for current user) and ultrasonographically-diagnosed NAFLD (OR: 0.75, 95% CI: 0.57-0.98 for current user) in the age, gender, ethnicity-adjusted model. On multivariate analysis, the ORs for suspected NAFLD comparing current light or heavy users to non-users were 0.76 (95% CI 0.58-0.98) and 0.70 (95% CI 0.56-0.89), respectively (P for trend = 0.001) with similar trends in ultrasonographically-diagnosed NAFLD (OR: 0.77, 95% CI: 0.59-1.00 for current user; OR: 0.71, 95% CI: 0.51-0.97 for current light user). In insulin resistance-adjusted model, marijuana use remained an independent predictor of lower risk of suspected NAFLD. CONCLUSIONS: In this nationally representative sample, active marijuana use provided a protective effect against NAFLD independent of known metabolic risk factors. The pathophysiology is unclear and warrants further investigation.
