As for Prison being no help, if the prisons are properly run, regular screening for substance abuse on the inmates & Staff, this would be the perfect place for them to get the treatment to help them come off the bloody stuff
No it wouldn't. It'd be a shit place for them to get treatment, and massively expensive. We can see this because countries that have stopped sending their drug addicts to prison and instead treat them are having significant success. We're not advocating some crazy experimental society. Better options are being demonstrated to us every ******* day by countries that have abandoned the ridiculous, arbitrary "war on drugs" and are actually trying to make a better society.
