Also I doubt you will find many addicts attempting to inject without finding a vein, and if they did this, all they would get is a little discomfort…

‘, but is it really a good idea to increase the risk that an injection will be done wrongly – maybe multiple times?’

This would be a fairly rich heroine addict who would waste alot of money pumping drugs into his arm, when most likely they would just go elsewhere!

The way I see it, the blue light hardly effects me, and if it lessons the risk of me bumping into a freshly high addict while going to the toilet, I cannot see the problem.

Yes, this is only moving the problem on, but at least its slightly protecting the public from a potential danger(including needles left on the floor).

As I see it, curing the heroine problem is a BIG task, verging on the impossible. The only steps I would try and take to fix it would be too give heroine addicts controlled, clean amounts of heroine from the NHS, this would reduce burglaries, and heroine related deaths. Also hopefully allowing the NHS to slowly reduce the amount or strength, gradually getting them of the drugs, however this will never happen:/

I have to hand a guidebook by a lighting manufacturer Zumtobel Staff titled ‘Lighting for the Workplace’ that points to research from, among others, Brown University that reports that the brain has a non-visual light receptor most sensitive to blue light.

Exposure to blue light apparently causes the production of melatonin in the pineal gland to be suppressed, making us more alert, since melatonin makes us sleepy. In this context, they are attempting to convince us that expensive light fittings containing blue light in the workplace make for more productive employees, but annecdotally it’s no secret that alert shoppers spend more.

You can experiment with this effect yourself if, like me, you work or spend time in a building with little daylight. Though there are many factors that cause that afternoon lull, you will probably find this lull is less severe if you take an outdoor lunch break for at least 20 minutes.

I suppose what I meant was that if drug users still choose to inject under blue light and make mistakes, or need multiple tries, the effect on bystanders may be worse than if they did it more easily under normal light. There may be more discarded needles, blood, or worse.

But yes, overall, it would seem that the aim is to move the problem on.

I don’t see it so much here in bars as I do in places that have free entry and unattended washrooms, like laundromats and pizza-by-the-slice joints.

I don’t buy the idea that there’s a bystander effect like there is with the poor-visibility intersections, though. All things being equal, washrooms without drug users are safer and more comfortable for their intended use, and if drug users decide to use the washroom to shoot up anyhow, the blue light doesn’t make it more dangerous for the intended use than a washroom with regular lights.
