Overall the authors concluded that “smoking is most likely associated with the negative progression and adverse outcomes of COVID-19.” One of the studies found that “smokers were 1.4 times more likely (RR=1.4, 95% CI: 0.98–2.00) to have severe symptoms of COVID-19 and approximately 2.4 times more likely to be admitted to an ICU, need mechanical ventilation or die compared to non-smokers.”

(2020) Smoking upregulates angiotensin-converting enzyme-2 Receptor: A potential adhesion site for novel coronavirus SARS-CoV-2 (Covid-19). Journal of Clinical Medicine, 9(3):841. doi:10.3390/jcm9030841. https://www.mdpi.com/2077-0383/9/3/841
The authors propose that a specific receptor, angiotensin-converting enzyme-2 (ACE2) receptor which is the known receptor for both the severe acute respiratory syndrome (SARS)-coronavirus (SARS-CoV) and the human respiratory coronavirus NL638, may be a novel adhesion site for the coronavirus that causes COVID-19. Smoking can lead to more of these receptors, which may be the reason they appear to be more susceptible to this illness. This could also be true for new electronic smoking devices such as electronic cigarettes and “heat-not-burn” IQOS devices.
Liu, W., Tao Z.-W., Lei W., Ming-Li Y., Kui L., Ling Z., Shuang, W., Yan, D., Jing, L., Liu, H.-G., Ming, Y., & Yi, H. (2020) Analysis of Factors Associated with Disease Outcomes in Hospitalized Patients with 2019 Novel Coronavirus Disease.

Lui and colleagues were one of the first to demonstrate the link between smoking and poor outcomes for COVID-19. A history of smoking was one of the factors that were identified as contributing to patients experiencing more serious health complications from COVID-19 infection (including progression of COVID-19 pneumonia and taking longer to recover from COVID-19 pneumonia).

This article details some of the mechanisms by which cigarette smoke and vaping aerosol may increase risk of developing COVID-19. For example, they conclude that cigarette smoking and vaping aerosol are linked to lung inflammation and lowered immune function. As well, a history of smoking was found to be one of the factors for the progression of COVID-19 pneumonia.

Dr. Neal Patel, a Mayo Clinic pulmonologist and critical care medicine specialist reinforces the message that smoking makes individuals more susceptible to developing COVID-19 and also encourages people to quit vaping, as well, to maintain lung health.
