Some recent writing

I’m just making a quick note of some recent writing.

I published a new post on the Antidotum Substack which reported on a recent paper on urine drug testing in people who use drugs.

• Vol.9: Shall I get a urine test before you see this person?°

I’ve also had some new posts about colourblindness on my 1 in 12 Substack. Those are:

• Everyday colourblindness: the blinking problem of red-green LEDs°
• Is Boris Johnson colourblind?°
• Stars and stripes - getting it wrong with football kits°
• Bladder cancer and colour vision°
• Colourblindness and cricket°

In the February 2024 issue of the BJGP my Editor’s Briefing:

• Patient perspective: the ghost in the machine°
