Older adults are the fastest growing group of cannabis users and are out-pacing other groups as new users. Clinical evidence indicates that cannabis may be helpful for select medicinal purposes in this population. Yet there is limited research about older adults experiences of starting to use cannabis in later life. The purpose of this study was to begin to address this gap. Methods: This study employed qualitative description. A convenience sample of Canadian community-dwelling older adults who were new users of cannabis were recruited. Data were...

In particular, the review examines experimental research on the acute effects of tetrahydrocannabinol (THC) on driving-related neurobehavioral skills and driving performance based on simulator and road course studies. The evidence indicates that certain driving abilities are significantly, albeit modestly, impaired in individuals experiencing the acute effects of THC. Treatment effects are moderated by dose, delivery method, recency of use, and tolerance development, with inconclusive evidence concerning the moderating influence of cannabidiol. Emerging research priorities include linking neurobehavioral deficits to specific decrements in driving...

Patients and physicians need to be aware of the important implications that such use may have for driving. Objective: The aim of this article is to briefly review the scientific evidence regarding cannabis and driving impairment and discuss current legal issues affecting patients, as well as to update physicians on relevant issues and the best guidance to offer their patients. Discussion: Delta-9-tetrahydrocannabinol (THC) impairs driving performance and can increase crash risk. These effects are more pronounced in people who use THC occasionally and can last for...

Abstract Background Cannabis can have an adverse impact on some mental health conditions, while many consumers report using cannabis to manage or improve mental health. Little data exists on how patterns of cannabis use differ by mental health status. The current study examined the prevalence of cannabis use and modes of cannabis administration among consumers who experienced a mental health condition in the past 12-months. Methods Data came from the International Cannabis Policy Study (Wave 1). Online surveys were conducted from Aug – Oct 2018 with 25,747 respondents aged 16–65, recruited from commercial panels in Canada...

One of the major concerns raised about increasing cannabis legalization and the therapeutic use of cannabis is that it will increase cannabis‐related harm. However, the impairing effect of cannabis during intoxication varies among individuals and may not occur in all users. There is evidence that the neurocognitive response to acute cannabis exposure is driven by changes in the activity of the mesocorticolimbic and salience networks, can be exacerbated or mitigated by biological and pharmacological factors, varies...

Abstract As more states in the U.S legalize recreational and medicinal cannabis, rates of driving under the influence of this drug are increasing significantly. Aspects of this emerging public health issue potentially pit science against public policy. The authors believe that the legal cart is currently significantly ahead of the scientific horse. Issues such as detection procedures for cannabis-impaired drivers, and use of blood THC levels to gauge impairment, should rely heavily on current scientific knowledge. However, there are many, often unacknowledged research gaps in these and related areas, that need to be addressed in order provide a more coherent basis for public policies....

The individual and public health burdens are less than those of other forms of drug use, but CUD accounts for a substantial proportion of persons seeking treatment for drug use disorders owing to the high global prevalence of cannabis use. Cognitive behavioural therapy, motivational enhancement therapy and contingency management can substantially reduce cannabis use and cannabis-related problems, but enduring abstinence is not a common outcome. No pharmacotherapies have been approved for cannabis use or...

Abstract Epilepsy is one of the most common neurological conditions worldwide. Cannabinoids, particularly cannabidiol (CBD) and tetrahydrocannabinol (THC), have demonstrated therapeutic potential in the treatment of epilepsy due to their interaction with the endocannabinoids system. Despite these developments, the use of medical cannabis is still complicated because of legal obstacles, the different psychoactive effects of different cannabinoid receptors, and concerns about long-term safety, especially in populations with young children. The development of new regulations will be essential to increasing access to patients' cannabis medications. Cannabis has the potential to change the therapeutic landscape for neurological illnesses like seizures, provided that science and regulation continue...

Abstract Importance  Cannabis use disorders (CUD) are associated with adverse health effects, including mental disorders and motor vehicle collision-related injuries. However, little is known about whether CUDs are associated with increased mortality risk. Objective  To examine whether individuals receiving incident hospital-based care (an emergency department visit or hospitalization) for a CUD is associated with increased risk of death. Design, Setting, and Participants  This population-based retrospective cohort study included all individuals aged 15 to 105 years living in Ontario, Canada, between 2006 and 2021 (n = 11 622 571 individuals). Overall and cause-specific mortality were compared between individuals with incident hospital-based CUD care and age- and sex-matched members of the general population...

Abstract Introduction A clinical trial of Epidiolex®, the only US FDA-approved cannabis-derived consumer product (CDP), discovered an interaction with an immunosuppressant (tacrolimus) that led to drug toxicity, highlighting the unique intersection of prescription and commonly unregulated consumer products. Objective We aimed to identify if similar drug–drug interactions (DDIs) are occurring among the consumer CDP market, even though they cannot be identified through trials. Methods We searched Reddit for subreddits related to CDPs or health, resulting in 63,561,233 posts. From these, we identified 190 posts discussing both immunosuppressants and CDPs. Two blinded investigators evaluated the following. (1)...
