People with mental illness

Smoking in people with mental health problems is common. The smoking rate of the Australian population is just over 15%,1 but for people with a mental health problem the rate is about 32%.22 In some cases, such as for people with schizophrenia, the rate is up to 66%.192

People with mental illness such as schizophrenia, depression, bipolar disorder and anxiety often experience physical, financial and social disadvantages because of their illness.193,194 There is evidence that people with mental illness are just as motivated to quit as the general population.195 Actively encouraging and assisting smoking reduction and cessation are important to improve their quality of life. Tobacco smoking can also interfere with the medications taken for schizophrenia and depression, and the doses of some psychotropic medications may need to be decreased.

Treating tobacco dependence is a worthwhile intervention for people with severe mental illness and may be just as effective as for the general population. However, it should be realised that cessation rates are generally lower in this group for any given level of assistance. A mix of face-to-face help augmented by Quitline calls is as effective as intensive face-to-face help. In people with stable psychiatric conditions it should not worsen mental health.194,196

In fact, smoking cessation is associated with reduced depression, anxiety and stress together with improved mood. This is true in those with and without a diagnosed psychiatric disorder.197

Health professionals should offer people with a mental illness smoking cessation interventions that have been shown to be effective in the general population.8 Mental illness is not a contraindication to stopping smoking but the illness and its treatment need to be monitored carefully during smoking cessation.198–200

Patients quitting smoking with any method are at some risk of increased psychological stress during the quitting process, but the risk is higher for those with a history of mental illness. Clinicians should monitor patients with mental illness more closely and advise prompt reporting of adverse events.
 

Recommended smoking cessation treatment

  • Intensive smoking cessation counselling and close follow-up are important in this group.
  • NRT is safe and effective for people with a mental illness.
  • Consultation with a psychiatrist may be considered for advice on use of medicines for smoking cessation in people with significant mental illness.
  • Bupropion may not be suitable for people with a history of seizures, people with a history of anorexia or bulimia and people using other antidepressants. Caution is needed if there is concomitant use of bupropion with drugs such as tricyclic antidepressants and selective serotonin reuptake inhibitors. These drugs should be initiated at the lower end of the dosage range while a smoker is taking bupropion. In the more common situation that bupropion is initiated for a person already taking such antidepressants then the dose of tricyclic, or selective serotonin reuptake inhibitor, may need to be decreased. Bupropion should not be used in patients taking monoamine oxidase inhibitors (MAOIs) including moclobemide. A 14-day washout is recommended between completing MAOIs and starting bupropion. Consultation with a psychiatrist may be considered for advice on co-prescribing bupropion with other antidepressants.
  • There is increasing evidence of the safety and efficacy of varenicline in people with significant psychiatric illness. Varenicline helps with withdrawal symptoms and takes away the pleasure of smoking. There have been reports of depressed mood, suicidal ideation and changes in emotion and behaviour using this product, though a meta-analysis of data from 17 clinical trials found no association.128 Several randomised trials have shown varenicline to be safe and effective in depression and schizophrenia.124–126 Therefore varenicline can be used in this population but prescribers should ask patients to report any mood or behaviour changes. Patients should be advised to stop taking varenicline at the first sign of any of these symptoms.
