\n\t\t\t\t\t\t\t\t\tSince late 2019, the entire world has faced the COVID-19 pandemic, an infectious disease whose main symptoms affect the respiratory system. Already weakened by tobacco consumption, smokers’ lungs are therefore even more vulnerable. However, some studies have suggested that nicotine could have a protective effect against severe forms of COVID-19. Should we believe this? Here is a comprehensive overview of the links between tobacco and COVID-19. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Faced with the rapid spread of SARS-CoV-2 between late 2019 and early 2020, many scientific teams worldwide mobilized to identify risk and protective factors against COVID-19. Among the many hypotheses examined, some preliminary studies caused surprise by suggesting that smokers were proportionally fewer among patients testing positive or hospitalized for COVID-19, compared to the general population. <\/p>

These results, primarily from retrospective analyses or hospital registries, suggested that nicotine might have a protective effect against the virus. Quickly relayed by the media, this hypothesis fueled some confusion in public opinion, sometimes perceived as a justification for continuing to smoke. <\/p>

However, caution was advised from the very first interpretations. These studies were primarily observational and not experimental, meaning they did not allow for \u201cestablishing a cause-and-effect link. Furthermore, several confounding factors were quickly identified. For example, severely ill COVID-19 smokers were sometimes less likely to be correctly identified as such, due to incomplete or poorly documented medical data upon admission.\u201d <\/p>

Moreover, behavioral elements may have skewed the results: smokers, often aware of their respiratory vulnerability, may have avoided testing sites or minimized their symptoms, which would artificially reduce their presence in hospital statistics.<\/p>

Finally, some of these studies were conducted in countries where tobacco consumption is highly stigmatized, which can lead to underreporting of smoking status, even in medical surveys. In summary, the methodology of these studies is largely questionable, and their results cannot in any way be used to justify or trivialize tobacco consumption in the context of the COVID-19 pandemic. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Despite the media interest generated by the idea that nicotine could have a protective effect against COVID-19, this hypothesis has never been rigorously validated by the international scientific community. The initial studies that suggested this link were very quickly questioned, particularly due to major methodological biases. <\/p>

Several criticisms were raised: the studied population samples were \u201coften neither representative nor large enough, the collected data were sometimes incomplete or poorly documented, and certain essential variables, such as the existence of comorbidities, lifestyle habits, or socioeconomic status, were not taken into account. Moreover, the screening methods used in these studies were often not very sensitive, which could lead to falsely reassuring results.\u201d <\/p>

Some of these publications were even withdrawn from scientific journals due to lack of peer validation or following additional checks revealing errors or hasty interpretations. Other studies, though conducted more rigorously, did not find a protective link between nicotine and SARS-CoV-2. <\/p>

Today, no solid scientific evidence confirms that tobacco or nicotine reduce the risk of contamination or severe forms of COVID-19. On the contrary, the most reliable data available to date tend to confirm that smoking is a significant aggravating factor in the progression of the disease, due to its impact on the respiratory and immune systems. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

According to the World Health Organization (WHO), smokers have a 40% to 50% higher risk of developing a severe form of COVID-19. This includes an increased likelihood of hospitalization, ventilation, intensive care admission, and even death. Other research estimates that this risk could be as high as 80% for heavy smokers. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In Algeria, tobacco remains one of the main preventable causes of mortality. According to the World Health Organization (WHO), it is responsible for over 15,000 deaths per year in the country. These alarming figures largely preceded the COVID-19 pandemic and highlight the massive health impact of smoking. <\/p>

Each cigarette contains over 4,000 harmful chemical substances, several of which are highly carcinogenic. Tobacco seriously harms health and is a triggering or aggravating factor for many chronic diseases:
\u2013 chronic bronchitis,
\u2013 recurrent respiratory infections,
\u2013 cancers (especially lung, throat, and bladder),
\u2013 high blood pressure,
\u2013 cardiovascular diseases,
\u2013 strokes (CVA),
\u2013 and chronic obstructive pulmonary diseases (COPD). <\/p>

These pathologies, already serious in themselves, also represent major comorbidities likely to significantly worsen the prognosis in case of COVID-19 infection.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In Algeria, smoking is a real public health issue. According to available data, nearly one in four adults is a smoker, with a particularly high prevalence among men. Tobacco is directly linked to the onset of serious chronic diseases, such as bronchitis, lung cancers, strokes (CVA), and high blood pressure. <\/p>

These conditions, referred to as comorbidities, are known to significantly worsen the \u201cprogression of a COVID-19 infection. Contrary to some misconceptions, the link between tobacco and COVID-19 is far from protective: on the contrary, it exposes smokers to more severe forms of the disease and major respiratory complications.\u201d <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tBehaviors associated with smoking also facilitate the spread of viruses. By frequently manipulating their masks to smoke, and by sharing lighters or cigarettes, smokers increase their exposure to the virus. Moreover, the chronic cough often linked to tobacco consumption disperses more viral particles into the environment. All these are reasons to consider quitting smoking as an essential preventive measure against COVID-19. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The link between COVID-19 and smoking is now well-documented. Smoking increases the risk of developing severe, even fatal, forms of the disease. Indeed, smokers often have chronic respiratory conditions (bronchitis, COPD) and cardiovascular comorbidities (hypertension, heart attack, stroke) that make them particularly vulnerable to SARS-CoV-2. <\/p>

In Algeria, this observation has been repeatedly highlighted by the Ministry of Health, particularly during successive waves of contamination. National and international experts warn that tobacco: <\/p>
