A childhood pal of mine lost his leg in much the same way. Drug abuse is not that odd in the part of Manchester i come from. I've seen one of my oldest and best friends try and fail many times to recover from his habit. Been clean for a few years now but like any addiction it's a continual battle for recovery
The drug strips them down, until that's all that people see, nothing else seems to remain at least to those that don't understand that these people are just ordinary people like the rest of us.
Diego, these people exist in our world, they slip between the cracks and become little more then glimpses in the eyes of passers by.
I do like the work you're doing and the reason for it, i would like you to show them in the world they inhabit, because it's our world to. The close head shots are good, but i think you'll also gain something by bringing them more in to the world
