A two-year follow-up on the effects of a smoking ban in an inpatient psychiatric service.

The effects of prohibiting cigarette smoking on the behavior of patients on a 25-bed psychiatric inpatient unit were assessed immediately after implementation of a smoking ban and two years later. No major behavioral disruptions were observed after the ban. The number of calls for security assistance, physical assaults, instances of leather restraints and of seclusions, and discharges against medical advice did not increase significantly immediately after the restriction on smoking or two years later. Significantly more verbal assaults and prescribing of p.r.n. medications for anxiety occurred immediately after the ban but not two years later.
