**6.1 Smoking free policy**

Despite the possible barriers to delivering a smoking-free policy in mental health patients, it is considered to have strong evidence for decreasing the early onset of smoking in adolescence, enhancing smoking cessation, lowering the harmful of secondhand smoking as well as reducing smoking-related morbidity and mortality [52]. Thus, psychiatric departments have implemented as they increasingly accepted smoking bans, although these policies appear to have no clear impact on behavioral indicators or compliance; furthermore, it has had little effect on smoking cessation [51]. Nevertheless, the smoke-free policy is required to be implemented as part of public programs that support smoking cessation interventions. Additionally, it is essential to approve smoking-free legislation to attain a high level of compliance, to enhance air quality and reduce secondhand smoke as well as improve health outcomes [6]. This legislation may also alter smoking behavior, increase the attempts of smoking cessation and contribute a long-term effect on smoking prevalence [6].

#### **6.2 Media campaign**

This is an important component of the comprehensive smoking control program, including a mass media education campaign, expanding healthcare coverage of smoking treatment, increasing the risk of smoking in the general population and particularly people with mental health issues [52]. Many pieces of evidence have shown that media campaigns are an effective way of improving smoking cessation and decreasing smoking prevalence; moreover, media campaigns of anti-smoking have revealed an effective reduction in tobacco use among the general population [6, 51]. Recently, the UK government has invested in an anti-smoking campaign focused on the health risk of smoking and the hazard of passive smoking because tobacco industries and pubicrelated activities are a source of misinformation [6, 15]. Therefore, governments are responsible for informing the public about the health risk of smoking and providing the right information about abstinence from smoking; similarly, the governments have a key role in the delivering of smoking prevention in relation to morbidity and mortality and implement a campaign focusing on the younger generation [15, 51].

An effective media campaign also promotes smoking cessation, reduces smoking prevalence, and supports policies of tobacco control programs.

### **6.3 Increase tobacco taxation**

Taxation of tobacco products is an effective way for smoking cessation and it also has been demonstrated to have an impact on behavioral smoking in the general population [51]. Tax increase on tobacco has induced the desired effect to deter adolescents from initiating to smoke and to encourage smokers to quit [52]; likewise, the efficacy of tobacco taxation depends on the accessible income of smokers, hence the tax increase might have a substantial effect on smoking people with mental illness [15]. Furthermore, tax increase tends to raise the price of tobacco resulting in reducing short-term tobacco use as well as decreasing smoking-related inequalities. Tobacco taxation is more likely to be effective in influencing the behavior of people with mental health issues [6].
