Didn't realise there was a British Toilet Association!... Whole proposal
is pretty macabre, actually. Worse than lying all OD'd and defunct in a public toilet would be lying thus under deeply unflattering blue light!

Blue veins, hence blue light will make it difficult to find the vein?

Do they not think any steps ahead?

See, if I was an addict in need of a fix, and found me a nice secluded toilet to shoot up in, and was greeted with the challenge of finding my bloody vein, I'd be pretty pissed off. If I then couldn't get my fix, I'd probably destroy something ... starting with that bloody blue light! ;-p

Ah well. It seems my neighbourhood homeless encampment has been reclaimed by the heroin addicts since I'm seeing needles here and there. I should phone the police.

You'd think city councillors could find somewhere else to shoot up. Let 'em use the backs of their chauffeur-driven cars. That's what chauffeurs are for, right? Drugs and sex in the back seat.

... clustered smoking outside the front of offices throughout the city.
