It is not bollocks. This was in 2018-2020. I was housed by the council in a ground floor maisonette. Next door to me was a man with substance abuse issues and MH issues who got cuckooed. My ex ended up becoming a crack addict due to being befriended by the people who inhabited what became like a doss flat. I got to know a lot of addicts.
They all had the same type of traumatic backgrounds, including my ex. Childhood trauma - raised partly or wholly in care, introduced to drugs young by adults, end up getting abused further by people in the care system etc. They turn to substances to cope. I don't blame them.
Our local co-op, which was the nearest shop they could walk to, banned some of them because they shop lifted so often. They'd still try and go in and grab stuff. They used to ask me for food when I was cooking dinner because they were hungry and had no money left as it had gone on drugs, drinks, tobacco or cigarettes. They would also ask me for teabags, rizlas, toilet roll, washing up liquid...
I fed them, I gave them things, I listened to their stories and tried to help them... I have been in some of their homes and seen how they live and how little real food they had. I've seen them with stolen alcohol and meat and other items.
I don't know why you think it is bollocks.
