Cannabis access laws allow for the use of cannabis in private and the trade, purchase and use of hemp-related products as a complementary medicine and for other benefits. Cannabidiol (CBD) has the treatment potential for several conditions but, with the lack of resources in South Africa to maintain the legislation, products contaminated with delta-9-tetrahydrocannabinol (Δ9-THC) are sold by some suppliers who do not comply with the legislative provisions in terms of the threshold concentrations for Δ9-THC. ⋯ Hemp- and CBD-containing products were analysed by gas chromatography-mass spectrometry and compliance was assessed for CBD and Δ9-THC purity against the legislative thresholds. A strategy based on metabolite ratios is suggested to distinguish between intentional or irresponsible cannabis use and legitimate CBD use.

Globally, alcohol intoxication has been shown to be significantly associated with increased risk for road traffic crash morbidity and mortality for all road users (drivers, passengers and pedestrians). This association relates to the diminished capacity of drivers while intoxicated to operate motor vehicles and the increased propensity for risk-taking behaviours. The overall prevalence of alcohol-related fatal crashes contributes significantly to the burden of disease in many countries. In South Africa, research into the relationship between alcohol intoxication and other driver risk behaviours is limited and variable, constraining appropriate and effective policy and programmatic options and interventions. ⋯ Improved enforcement to prevent alcohol intoxication using roadblocks is required in a focused manner during specific temporal periods (at night, over weekends and during non-vacation periods), while enforcement to prevent speeding and other driver risks should be prioritised during other periods using speed monitoring and mobile visible policing, respectively. There is an urgent need to improve the current measurement of alcohol attribution in fatal crashes, to ensure more accurate estimation of prevalence, and to improve analysis and understanding of the compound impact of alcohol intoxication on all other driver risk behaviours and associated fatal crashes.

Hookah pipe (HP) smoking is perceived as a harmless activity, enjoyed by young adults and high school-going children. Awareness of the health impact of recreational habits, and their intersection with new social norms in the COVID-era, requires critical review. We describe a case series of young HP smokers presenting with secondary polycythaemia with significant clinical sequelae necessitating extensive work-up. HP smoking may lead to acute and chronic carbon monoxide intoxication, with resultant secondary polycythaemia and complications including provoked thrombosis.
