Drug and Alcohol addicts have made a concious choice to abuse what God has given them, people stay on drugs because they are too lazy to make the effort and change their behaviour, its just too hard and they know best anyway. Some do want to change but only usually when they are facing prison, they can opt for community treatment and walk free from the courts!
Residential detox is effective but prohibitively expensive.
Needle Exchange is woefully under used so needles are being resued and shared, this increases HEP B and C infections. this is also an indication of lazyness. did you know that anyone can walk into boots and demand a needle exchange kit, just give a fake date of birth, and bobs your uncle!
