The protection conferred by smoking for a respiratory disease has so far only been described for hypersensitivity pneumonitis (HP), especially for farmer's lung, and to a lesser degree, for bird fancier's lung. The under-representation of active smokers in SARS-CoV-2 patients suggests a protective effect of smoking, similar to that in the farmer's lung. We chose to highlight the most obvious similarities between SARS-CoV-2 and farmer's lung but there are probably others, especially concerning the hyperactive immune response described as 'cytokine storm'. The lack of knowledge about the mode of action of smoking in farmer's lung disease limits comparisons with SARS-CoV-2 and more research is required.	./cache/cord-341883-eh0aw3re.txt	./txt/cord-341883-eh0aw3re.txt
