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.

The onset of the COVID-19 pandemic in South Africa (SA) created numerous supply challenges. Demand for diagnostic testing overwhelmed the capacity to deliver. We describe the utility and outcomes of a mobile laboratory staffed by non-laboratory healthcare workers and established to perform polymerase chain reaction (PCR) testing for the rapid diagnosis of COVID-19 at a large hospital in SA. ⋯ The establishment of a mobile PCR laboratory staffed by non-laboratory healthcare workers during the COVID-19 pandemic provided a rapid, accurate and clinically effective solution for emergency hospital admissions with non-COVID-19 presentations.

Delirium is associated with increased mortality and length of hospital stay. Limited data are available from HIV-infected acute hospital admissions in developing countries. We conducted a prospective study of delirium among acute medical admissions in South Africa (SA), a developing country with universal antiretroviral therapy (ART) access and high burdens of tuberculosis (TB) and non-communicable disease. ⋯ Delirium is common and is associated with increased mortality in HIV-infected acute medical admissions in endemic settings, despite increased ART use. Older HIV-infected patients with renal dysfunction are at increased risk for inpatient delirium, while those using ART on admission have a reduced risk.
