On drugs?

'Service user': Doesn't it sound like a person addicted to a drug? I'm a user of services. It does imply that the person is dependent on services which might be true. But that harks back to the medical model of dependency. Are the terms 'client' or 'customer' better? They have commodified connotations and may imply that the professional has all the answers or the product to be sold. What do the actual people who access service support want to be called? Is it service user?
