Tackling drug use

The Association of Directors of Social Work has contributed significantly to policy debates over many years and its perspective on drugs and their impact on families is to be respected. I know particularly from my constituents' experience the positive impact effective social work practice can deliver. However, I'm not terribly clear on the precise point Bernadette Docherty, current president, was attempting to make (Letters, July 27), apart from a partisan endorsement of SNP policy, a rather surprising departure for her organisation.
