Can i get cotinine out of my system in 5 days?

A doctor has provided 1 answer

Likely, if no more : Tobacco. There are variations in elimination with type of tobacco, lean body mass, race and gender. Average half life of cotinine is about 20 hours so on average five days would allow 5 half lives which is usually sufficient to test negative. Please note that these are averages and may not apply in an individual person. See this site for more info. http://www.ncbi.nlm.nih.gov/pubmed/1252140.
