I smoke alot and im obese. if i quit smoking on 12/15/15 will the nicotine and cotinine be out of my urine, saliva, and blood by 1/1/16?

Probably not all.: Saliva - yes. “When someone stops using tobacco & nicotine products, it can take more than 2 weeks for the blood level of cotinine to drop to the level that a non-tobacco user would have & several weeks more for the urine level to decrease to a very low concentration.” REF: http://labtestsonline.org/understanding/analytes/nicotine/tab/test/.
