A 2021 report showed that current smokers were 80% more likely to be admitted to the hospital and were significantly more likely to die from COVID-19. This suggests that smoking may worsen COVID-19 symptoms and recovery.
According to a 2022 study, smoking increases the risk of post-acute COVID-19 syndrome. This is the medical term for COVID-19 symptoms or complications that develop or persist 4 weeks after the initial onset of symptoms.
