Clinical Epigenomic Explanation Of The Epidemiology Of Cannabinoid Genotoxicity Manifesting As Transgenerational Teratogenesis, Cancerogenesis And Aging Acceleration, Albert Stuart Reece, Gary Kenneth Hulse
Clinical Epigenomic Explanation Of The Epidemiology Of Cannabinoid Genotoxicity Manifesting As Transgenerational Teratogenesis, Cancerogenesis And Aging Acceleration, Albert Stuart Reece, Gary Kenneth Hulse
Research outputs 2022 to 2026
As global interest in the therapeutic potential of cannabis and its’ derivatives for the management of selected diseases increases, it is increasingly imperative that the toxic profile of cannabinoids be thoroughly understood in order to correctly assess the balance between the therapeutic risks and benefits. Modern studies across a number of jurisdictions, including Canada, Australia, the US and Europe have confirmed that some of the most worrying and severe historical reports of both congenital anomalies and cancer induction following cannabis exposure actually underestimate the multisystem thousand megabase-scale transgenerational genetic damage. These findings from teratogenic and carcinogenic literature are supported by …

The International Cannabis Toolkit (Icanntoolkit): A Multidisciplinary Expert Consensus On Minimum Standards For Measuring Cannabis Use, Valentina Lorenzetti, Chandni Hindocha, Kat Petrilli, Paul Griffiths
Faculty and Student Publications
Background: The lack of an agreed international minimum approach to measuring cannabis use hinders the integration of multidisciplinary evidence on the psychosocial, neurocognitive, clinical and public health consequences of cannabis use. Methods: A group of 25 international expert cannabis researchers convened to discuss a multidisciplinary framework for minimum standards to measure cannabis use globally in diverse settings. Results: The expert-based consensus agreed upon a three-layered hierarchical framework. Each layer—universal measures, detailed self-report and biological measures—reflected different research priorities and minimum standards, costs and ease of implementation. Additional work is needed to develop valid and precise assessments. Conclusions: Consistent use of …

Congenital Anomaly Epidemiological Correlates Of Δ8thc Across Usa 2003–16: Panel Regression And Causal Inferential Study, Albert Stuart Reece, Gary Kenneth Hulse
Research outputs 2022 to 2026
Δ8-Tetrahydrocannabinol (Δ8THC) is marketed in many US states as ‘legal weed’. Concerns exist relating to class-wide genotoxic cannabinoid effects. We conducted an epidemiological investigation of Δ8THC-related genotoxicity expressed as 57 congenital anomaly (CA) rates (CARs) in the USA. CARs were taken from the Centers for Disease Control, Atlanta, Georgia. Drug exposure data were taken from the National Survey of Drug Use and Health, with a response rate of 74.1%. Ethnicity and income data were taken from the US Census Bureau. National cannabinoid exposure was taken from Drug Enforcement Agency publications and multiplied by state cannabis use data to derive state-based …
Co-Occurrence Across Time And Space Of Drug- And Cannabinoid- Exposure And Adverse Mental Health Outcomes In The National Survey Of Drug Use And Health: Combined Geotemporospatial And Causal Inference Analysis, Albert Stuart Reece, Gary Hulse
Co-Occurrence Across Time And Space Of Drug- And Cannabinoid- Exposure And Adverse Mental Health Outcomes In The National Survey Of Drug Use And Health: Combined Geotemporospatial And Causal Inference Analysis, Albert Stuart Reece, Gary Hulse
Research outputs 2014 to 2021
Background: Whilst many studies have linked increased drug and cannabis exposure to adverse mental health (MH) outcomes their effects on whole populations and geotemporospatial relationships are not well understood.
Methods
Ecological cohort study of National Survey of Drug Use and Health (NSDUH) geographically-linked substate-shapefiles 2010–2012 and 2014–2016 supplemented by five-year US American Community Survey. Drugs: cigarettes, alcohol abuse, last-month cannabis use and last-year cocaine use. MH: any mental illness, major depressive illness, serious mental illness and suicidal thinking. Data analysis: two-stage, geotemporospatial, robust generalized linear regression and causal inference methods in R.
Results
410,138 NSDUH respondents. Average response rate 76.7%. …
Is There Less Opioid Abuse In States Where Marijuana Has Been Decriminalized, Either For Medicinal Or Recreational Use? A Clin-Iq, Aaron M. Wendelboe, Richard Mathew, Tana Chongsuwat, Elizabeth Rainwater, Mark A. Wendelboe, Elizabeth Wickersham Md, Ann F. Chou

Opioid use, abuse, and associated mortality have reached an epidemic level. In some states, cannabis is being used to treat chronic pain. To examine the hypothesis that medical marijuana legislation may reduce adverse opioid-related outcomes if patients substitute cannabis for opioids for pain management, we conducted a clinical inquiry (Clin-IQ). We searched Ovid MEDLINE, Ovid MEDLINE In-Process, and Embase for studies using the search terms marijuana, cannabis, legal, marijuana smoking, medical marijuana, opioid-related disorders, cannabis use, medical cannabis, legal aspect, and opiate addiction. We included population-based articles published from January 1, 2012, through December 5, 2018, that assessed the relationship …
Cannabis Consumption Patterns Explain The East-West Gradient In Canadian Neural Tube Defect Incidence: An Ecological Study [Dataset], Albert Stuart Reece, Gary Kenneth Hulse

While a known link between prenatal cannabis exposure and anencephaly exists, the relationship of prenatal cannabis exposure with neural tube defects (NTDs) generally has not been defined. Published data from Canada Health and Statistics Canada were used to assess this relationship. Both cannabis use and NTDs were shown to follow an east-west and north-south gradient. Last year cannabis consumption was significantly associated (P < .0001; cannabis use–time interaction P < .0001). These results were confirmed when estimates of termination for anomaly were used. Canada Health population data allowed the calculation of an NTD odds ratio) of 1.27 (95% confidence interval = 1.19-1.37; P < 10−11) for high-risk provinces versus the remainder with an attributable fraction in exposed populations of 16.52% (95% confidence interval = 12.22-20.62). Data show a robust positive statistical association between cannabis consumption as both a qualitative and quantitative variable and NTDs on a background of declining NTD incidence. In the context of multiple mechanistic pathways these strong statistical findings implicate causal mechanisms.

Background. Cannabis and tobacco have contrasting cognitive effects. Smoking cannabis with tobacco is prevalent in many countries and although this may well influence cognitive and mental health outcomes, the possibility has rarely been investigated in human experimental psychopharmacological research.
Method. The individual and interactive effects of cannabis and tobacco were evaluated in 24 non-dependent cannabis and tobacco smokers in a randomized, placebo-controlled, double-blind, 2 (cannabis, placebo) × 2 (tobacco, placebo) crossover design. Verbal memory (prose recall), working memory (WM) performance including maintenance, manipulation and attention (N-back), psychotomimetic, subjective and cardiovascular measures were recorded on each of four sessions.
Results. Cannabis …
