Benefits of Smoking Cessation and the Role of Health Professionals
With tobacco involved in the deaths of more than eight million people globally, every year (WHO 2019), health professionals play an essential role in supporting people with cessation.
In Australia, tobacco smoking is a major contributor to preventable illness and death. In fact, it is estimated to contribute to the deaths of almost 19,000 Australians every year (ABS 2019).
Smoking cessation, the process of quitting smoking, is imperative to the health of every individual who smokes. Regardless of age or smoking-related conditions that have already developed, there are immediate and long-term health benefits to be gained by quitting (Cancer Council 2019).
Cessation is a difficult process due to the addictive property of nicotine in cigarettes. Dependence is a chronic condition and those who smoke will experience withdrawal symptoms when they attempt to abstain.
It’s important for anyone embarking on the cessation journey to remember that only a minority of initial cessation attempts are successful, with the average 40-year-old who smokes having made about 20 attempts on average (RACGP 2019). Therefore, a failed first attempt is not necessarily the end, but indeed an important first step on the road to recovery.
The most effective way to attempt cessation is through a combination of behavioural support and medication (RACGP 2019.).
Why Attempt Cessation?
Tobacco smoking contributes to the risk of health issues including but not limited to heart disease, diabetes, stroke, cancer, renal disease, eye disease and respiratory conditions (ABS 2019).
Of these conditions, cancer is the largest cause of smoking-related death and illness, with about 22% of the cancer burden attributed to smoking. There are over 7,000 chemicals in tobacco smoke, more than 70 of which are carcinogens (AIHW 2018; 2020).
In 2015, smoking was also attributed to:
- 41% of respiratory diseases;
- 11.5% of cardiovascular diseases; and
- 3.7% of endocrine disorders.
As well as being directly involved in numerous diseases and health problems, smoking is also a risk factor for a myriad of other conditions including Crohn’s disease, back pain, sleep disorders and autoimmune diseases (Quit n.d.).
It is also worth noting that people who smoke have a significantly greater vulnerability to COVID-19. This is because smoking may cause lung disease or reduced lung capacity, which increases the risk of serious illness. Furthermore, cigarettes or fingers could be contaminated, resulting in possible transmission of the virus during the act of smoking (WHO 2020).Pregnancy
Smoking during pregnancy can have serious adverse effects on the fetus and contribute to the risk of pregnancy complications (RACGP 2019). These consequences include:
- Low birth weight;
- Being small for gestational age;
- Preterm birth;
- Perinatal death;
- Placental abruption;
- Cleft palate;
- Cleft lip; and
- Childhood cancers.
In addition to the potential long-term consequences for the smoker outlined above, smoking can also cause serious harm to others who breathe in the smoke second-hand and may exacerbate other conditions they may have (Better Health Channel 2019).
Second-hand smoke increases the risk of developing lung cancer by 20 to 30%, even if that individual has never smoked themselves. Infants and children are particularly susceptible to suffering adverse effects from second-hand smoke (CDC 2020).
About 1.2 million deaths every year can be attributed to passive smoking (RACGP 2019).What are the Benefits of Cessation?
Quitting has immediate effects, and will continue to progressively improve the individual’s health as time goes on (Cancer Council 2019).
- After 12 hours, excess carbon monoxide is out of the system.
- After 5 days, most nicotine is out of the system.
- After one week, the senses of smell and taste improve.
- After one month, skin appearance will likely improve.
- After two months, the lungs are no longer producing extra phlegm.
- After three months, lung function and circulation improves.
- After one year, the risk of heart disease is halved.
- After five years, the risk of stroke is significantly decreased.
- After 10 years, the risk of lung cancer is halved.
- After 15 years, the risk of heart attack and stroke is the same as someone who has never smoked.
(Australian Government Department of Health 2019)
Additionally, evidence shows that quitting may increase an individual’s life expectancy by about 3 to 10 years, depending on their smoking habits and age at cessation. Those who quit before the age of 30 may avoid excess risk of smoking-related death entirely (Cancer Council Victoria 2016).
Cessation will also protect others from the detrimental effects of cigarette smoke.What is the Role of Healthcare Professionals in Cessation?
Healthcare professionals of all kinds play a crucial role in supporting cessation. They should identify clients who smoke and offer advice, treatment or referral for cessation at every opportunity, especially during periods where their smoking habits are particularly problematic (e.g. if they present with smoking-related diseases, if they are hospitalised or if they are pregnant) (RACGP 2019).The 5As Intervention Method
The 5As are Australian guidelines for health professionals to address and assist with smoking cessation (RACGP 2019).
- Whether the client has a nicotine dependence by asking questions (e.g. how long after waking does the client smoke their first cigarette?)
- Whether there are any barriers to quitting, and if so, address the barriers with evidence-based strategies.
- Establish a quit plan, suggest strategies and address barriers.
- Assistance may include advice and support, referral or a combination.
Health professionals should recommend pharmacotherapy to all clients with nicotine dependence in addition to behavioural support. Medications used to support cessation are proven to be effective (RACGP 2019).
Refer to the RACGP’s guide for more information on supporting a person’s smoking cessation.Additional Resources
