Tobacco use is the leading preventable cause of death in the United States and contributes up to 24% of all VA healthcare costs. Veterans enrolled in the VA healthcare system smoke substantially more than the general population, which is particularly true among Veterans diagnosed with mental illness. Patients with bipolar disorder or schizophrenia have the highest smoking rates (69% and 58-90%, respectively) followed by those with PTSD (45-63%) and depression (31-51%). Numerous barriers exist for tobacco cessation among mental health patients, including high nicotine dependency, low rates of follow through for referrals, and limited availability of tobacco treatment tailored to their needs.
