Speedy dilute-and-shoot 

Researchers from the University of Rochester Medical Center, NY, United States, report a liquid chromatography-tandem mass spectrometry assay that quantifies cannabis metabolites THC-COOH and THC-COO in human urine. The assay uses a direct dilute-and-shoot approach that simplifies the sample preparation process, and improves overall throughput for a quick and accurate cannabis use detection method. The turnaround time was five minutes – a significant improvement over existing dilute-and-shoot assays that typically take 20 minutes. Researchers believe this new method can be easily applied and routinely performed in any clinical laboratory setting.

A solution to the opioid crisis?

Although the US is at the center of the opioid crisis, the issue is an increasing public health concern in other countries – including the UK, Sweden, and Australia. As such, researchers from Florida, US, decided to investigate the effects of medical cannabis on opioid use. The study revealed that medical cannabis patients are reporting decreased opioid use and overall improvements in health functioning after legalization – potentially confirming cannabis’ harm reduction role. Although the study included some limitations – such as self-selected participants and potential recall bias – the researchers are hopeful that this may have a positive impact on public health decisions.
