“I was working on ‘Detox’ from 2003-2005. I was initially attracted to the vividness of the blue lighting without really knowing why the light was used. Through research I found that the lights are used to deter intravenous drug use, usually within public toilets, specific spaces in which habitual users have been known to frequent. The reasoning behind their use is that under blue light it is difficult to find a vein. Veins being a blue/green colour do not appear visible to the eye under such conditions therefore restricting intravenous drug use within these spaces.
‘Detox’ deals with the stark contrast that exists between this arresting colour and the functional purpose of its installation in pubic spaces. The work enters into a discourse surrounding addiction and the control of the state and semi-public organisations. Heroin, along with crack cocaine above all other substances, seem to possess such power over the individuals concerned. For me each light, apart from performing a desired function, stands as a form of vigil light in the same way a lighthouse warns approaching ships.“
