how long does tobacco stay in saliva and mucous membrane?

Too long: Any smoker or tobacco chewer has residues that enter the tissue of the oral mucosa and leads to leukoplakia (white lesions} that are pre-cancerous. Don't smoke and you won't croke!

Tobacco homesteading: Nicotine can typically stay in the salive for 4-7 days. How long it stays in the mucous membranes in the body are determined by amount and frequency of exposure. If you smoke heavily and every day it will likely always be there, generally the exposure will last as long as 3-5 days if not repeated.
