I work with women leaving prison and am also a former prisoner myself albeit a few years ago.
The women's estate is not like this although it's not without its problems.
The men's estate is packed to the rafters with drugs and men that are constantly in and out.
So, this begs the question where is it all going wrong.
IME, the money thrown at drug treatment services is immense. In our area alone it's 22m and we have drug issues that are rife where I live. The services near us are widely criticised due to the level of dealing that goes on outside the building.
There is also the issue of how addiction is treated. Our local services are keeping scripts low in dosage thus rendering people unable to maintain sobriety. It is also fact that people are brainwashed into believing that it is not their fault they have an addiction. Known as PSI programmes, they are unlikely to address the underlying issues.
The cost of short-term sentencing is huge as is the cost of criminality to local communities by addicts.
Our prisons are full and those with MH acute conditions are being denied treatment due to those with addictions. It's also cheaper to house a person in prison (£112 per day) than to hospitalise a person at a cost of £450 per day.
It's a huge problem and the issues are behind walls too high for us to see over.
