Health risks of smoking include lung cancer and increased loneliness

Recent medical findings highlight the diverse health risks associated with smoking, spanning both physical and psychosocial dimensions. While smoking accounts for approximately 85% of lung cancer cases, research indicates that 5% to 20% of lung cancer diagnoses occur in individuals who have never smoked. Risk factors for non-smokers include secondhand smoke, air pollution, radon, occupational exposure to substances like asbestos or silica, and indoor air pollution from burning biomass or coal.

Beyond physical ailments, a study of over 50,000 people across 15 European countries suggests a link between smoking and increased feelings of loneliness. Presented at the European Respiratory Society Congress, the research found that smokers reported higher levels of loneliness and experienced a faster increase in these feelings over a two-year period compared to non-smokers. Experts suggest this may be due to nicotine dependence serving as a substitute for social interaction or smoking-related illnesses limiting social mobility.
