Pilot Testing a Digital Intervention to Improve Smoking Cessation in Persons With Serious Mental Illness

All patients with serious mental illness are abstinent while in the hospital for a psychiatric admission yet almost all return to smoking after discharge. The investigators propose to test a digital intervention adapted to the needs of SMI smokers and to being introduced in the inpatient psychiatric setting. Such an intervention could bridge the inpatient to outpatient gap in cessation services and will help people remain abstinent following hospital discharge.
