Why do people with mentalhealth issues smoke more?
• Relief of stress
• Self medication
• Increased vulnerability to smoking
• Misleading messages about smoking
• Institutional and cultural factors:– Inpatient psychiatric units– staff/patients beliefs– reward/punish practices.
Deprivation

Conclusions
• Psychotic symptoms, ‘as required medication’ usage and aggressive incidents did not rise, dispelling myths that restricting smoking would destabilise mental state
• The study revealed patient and staff beliefs about smoking and smoke restriction
• It also highlighted practical considerations relating to patient and staff anxieties about facing smoking restrictions.
• The positive results achieved relating to patients’ mental and physical health, should provide encouragement to other psychiatric units considering smoking restrictions
• Enforcing total smoking cessation in open psychiatric inpatient wards will be more challenging
