Abstract: The SARS-CoV-2 virus, which causes COVID-19, enters cells by binding its spike (S) protein to the angiotensin-converting enzyme 2 (ACE2) receptor. Some studies have mistakenly suggested that nicotine may protect against this infection by blocking viral entry through nicotinic acetylcholine receptors. However, it is well known that smoking worsens COVID-19 outcomes due to its negative impact on respiratory health. This study examined the link between tobacco exposure and the severity of SARS-CoV-2 infection using 183 questionnaires from COVID-19 patients. The analysis included factors like gender, age, physical activity, smoking status, vaccination, and sequelae. Participants were mostly aged 18-25 (57.4%) and 53.6% engaged in daily physical activity. Smoking statuses included 29.5% active smokers, 25.1% former smokers, and 45.4% non-smokers, with smokers having fewer multiple infections. Hospitalization rates were similar among all groups: 14.8% for active smokers, 12.0% for former smokers, and 10.7% for non-smokers. Vaccination was prevalent among 75.4% of participants. Active and former smokers reported higher instances of sequelae, such as memory issues and fatigue, compared to non-smokers. It is essential to address misconceptions about smoking and COVID-19 and promote smoking cessation. Further research is needed to fully understand smoking's impact on COVID-19 and its long-term effects.
