Do you think rehab works?

Residential rehab offers drug users some time away from drugs and the drug-taking environment. It can also offer therapy, counselling, medication and other services. It's usually found in the private sector, although some local authority funding is available for people who need it.

You hear a lot about celebrities 'going into rehab' – but is it a good solution to drug addiction or just a waste of money? Some professionals in addiction services think it's much less effective than treating addicts in the community. Others argue that time away from drugs is a good thing, even if the patient relapses after leaving.
