I have been told to avoid supplementing with quercetin if I smoke or have smoked cigarettes. It can develop lung cancer. Any info I can read on this?

Sorry, bad link. Here it is. https://pubmed.ncbi.nlm.nih.gov/28648644/.

The study is called "Quercetin suppresses the metastatic ability of lung cancer through inhibiting Snail-dependent Akt activation and Snail-independent ADAM9 expression pathways" It supresses metastasis in lung cancer.
