高市首相「喫煙増えている」→ 背景のストレスに注目
A hypothetical statement by PM Takaichi is buzzing online: "Isn't the rise in smoking due to underlying stress?" While many empathize with the struggle against stress, others question if this encourages smoking or demand more fundamental solutions, sparking a heated debate. The discussion highlights varying perspectives on addressing social stress and public health.

Nicotine Addiction and Stress
Nicotine addiction is not merely a habit but a type of drug dependence caused by nicotine's action on the brain's reward system. When we experience stress, our bodies secrete stress hormones like cortisol, increasing anxiety and tension. At such times, nicotine consumed through smoking promotes dopamine release in the brain, temporarily providing pleasure and relaxation. Therefore, many smokers tend to reach for tobacco as a means to alleviate stress. However, this effect is temporary; once nicotine leaves the body, stress and withdrawal symptoms reappear, leading to a vicious cycle of craving more tobacco. Particularly, chronic stress factors in modern society, such as economic insecurity, complex human relationships, and excessive work, often lead to smoking being mistakenly perceived as a form of "self-medication" for stress. Yet, it is scientifically proven that smoking increases numerous health risks, including cardiovascular disease, cancer, and respiratory illnesses. In the long run, smoking does not alleviate stress but rather causes new health concerns and financial burdens. This issue should not be dismissed as a mere matter of individual willpower but rather highlights the need for society as a whole to address the root causes of stress and promote healthy stress coping mechanisms.
Tobacco Tax and Public Health Policy
Tobacco tax is a crucial source of national revenue, as well as a tool for public health policy aimed at curbing smoking rates. Many countries believe that increasing the price of tobacco helps deter smoking initiation and encourages existing smokers to quit. For example, in Japan, tobacco taxes have been raised multiple times over the past two decades, each time resulting in a temporary, but noticeable, decrease in smoking rates. The adult smoking rate, which was 24.9% in 2003, decreased to 27.1% for men and 7.6% for women in 2019 (according to the Ministry of Health, Labour and Welfare's "National Health and Nutrition Survey"). However, the pace of decrease has slowed recently due to the spread of heated tobacco products. The purpose of tobacco tax is not only to secure financial resources but also to contribute to the overall health promotion of the nation, including curbing the increase in medical expenses caused by smoking and funding measures against passive smoking. However, it is also pointed out that tax increases could inadvertently increase the burden on stressed populations or encourage the distribution of illegal tobacco. Prime Minister Takaichi's statement can be seen as suggesting the need to re-examine the complex relationship between tobacco tax and public health policy, particularly from the perspective of national stress levels and smoking behavior.
Mental Health and Socioeconomic Factors
Mental health, or psychological well-being, is a critical factor significantly impacting individual happiness and overall societal productivity. In modern society, widening economic disparities, an increase in non-regular employment, long working hours, weakening human relationships, and more recently, changes in lifestyle due to the COVID-19 pandemic, are cited as socioeconomic factors that exacerbate people's mental burden. These factors intricately intertwine, increasing the incidence of mental illnesses such as depression and anxiety disorders, and also making it more likely for stressed individuals to engage in unhealthy behaviors like smoking and excessive drinking. For example, according to OECD data, mental health issues among workers in Japan are estimated to result in economic losses amounting to several trillion yen annually through presenteeism (a state where one is present at work but has low productivity due to poor physical or mental health). Prime Minister Takaichi's recognition of an "increase in smoking" likely serves as a warning against the rise in society's overall, often invisible, stress levels and its impact on individual health behaviors. Fundamental stress countermeasures are essential, including improving working environments, expanding economic support, enhancing access to mental healthcare, and promoting societal understanding of mental well-being. The smoking problem can be viewed as one symptom reflecting these underlying issues.
