Job seekers who smoke aren't welcome at the Detroit Medical Center. The health system on Wednesday joined a growing number of companies, mostly hospitals, that require new applicants to be tested for tobacco. The policy does not apply to current smokers, though they are encouraged to stop smoking and participate in cessation programs. In Michigan, the DMC joins the Lansing-based Sparrow Health System, the Oakwood Healthcare System in Dearborn and the Crittenton Hospital Medical Center in Rochester to adopt the no-smoking policy for applicants.
