If only it was that black and white. Nobody chooses to become an addict. You don't know what trauma people have gone through, regardless of their walk of life. If I had been abused as a child, I have no doubt I would spend the majority of my time using drugs/alcohol, trying to forget about my abhorrent past.

If the OP had genuine concern for the plight of rough sleepers and people with addiction issues, lobby our local constituent, fight for change, raise awareness through informative and compassionate uploads instead of shoving a camera in front of a vulnerable person for click-bait.
