Cilia in lungs and smoking:
Smoking destroys cilia, which are tiny hairs in your lungs located in a thin layer of mucus in the upper airways and breathing tubes. The cilia's main function is to protect your lungs against infection. Dirt and pathogens, which are trapped by the layer of mucus, are pushed up and out of the lungs by the wave-like movements of the cilia.
Seems the opposite is the more likely in that less cilia = less mucus membranes in the bronchiole which appears to be this virus’s favorite locus of host cell infection. Maybe smokers can breath in the pathogen and exhale before it can find a suitable host. Unless like you say it's a property of nicotine that is protecting users.
Less mucus production and means of transport(cilia) is the reason smoker coughs are violent yet unproductive.
So much for "we can't let the cure be worse than the disease"
