Impacts of medical and non-medical cannabis on the health of older adults: Findings from a scoping review of the literature
17/02/2023

The effects of medical cannabis are inconsistent within specific patient conditions. For older adults, generally, the available evidence suggests cannabis use may be associated with greater frequencies of mental health issues, substance use, and acute healthcare use, and the benefit-to-risk ratio is unclear. Studies with a balanced assessment of benefits and harms may guide appropriate public health messaging to balance the marketing pressures of cannabis to older adults.
Cyberbullying involvement, parental support, and cannabis use among adolescents
13/08/2022

Our results showed that cyberbullying involvement in any role (i.e., cyberbullying victim only, cyberbullying perpetrator only, or cyberbullying perpetrator-victim) was associated with greater odds of cannabis use after adjusting for important covariates. Results further indicated that higher parental support was associated with lower odds of cannabis use in a dose-response fashion. Higher parental support was also associated with a lower risk of cyberbullying involvement.
Potential Benefit of Add-on Δ9-Tetrahydrocannabinol in Pediatric Drug-Resistant Epilepsy: A Case Series
29/06/2021

Based on our experiences and reports in the literature, we propose that, in patients who fail management with an initial trial of high-dose CBD-focused therapy, there may be a role for add-on THC-focused formulations.
Maternal cannabis use in pregnancy and child neurodevelopmental outcomes
10/08/2020

With the legalization of recreational cannabis in many jurisdictions, there is concern about potentially adverse childhood outcomes related to prenatal exposure.
Cannabis treatment in children with epilepsy: Practices of Canadian neurologists
04/03/2020

The majority of Canadian pediatric neurologists consider using cannabis as a treatment for epilepsy in children. With many gaps in evidence and high patient-driven demand for cannabis therapy, this survey provides immediate information from the “wisdom of the crowd,” to aid neurologists until further evidence is available.
Cannabis use for therapeutic purposes by children and youth at a tertiary teaching hospital in Canada: A retrospective chart review
02/03/2020

Medically supervised cannabis use occurred most often in patients with intractable or refractory seizures. According to these data, seizure response is variable, and initial decreases may be transient for pediatric patients using cannabis. To ensure greater consistency and rigour in the conduct of prospective research and thus to generate better-quality research on the therapeutic effects of medical cannabis, development of a standardized care record is needed.
Association Between Self-reported Prenatal Cannabis Use and Maternal, Perinatal, and Neonatal Outcomes
18/06/2019

Among pregnant women in Ontario, Canada, reported cannabis use was significantly associated with an increased risk of preterm birth.
Trends and correlates of cannabis use in pregnancy: a population-based study in Ontario, Canada from 2012 to 2017
01/11/2018

Cannabis use in pregnancy has increased since 2012 in Ontario and was reported in about 2% of pregnancies in 2017.
