How Long Does It Take To Get Rid Of Nicotine From The Body?
When you take a single puff of a cigarette, it takes about 20 minutes for nicotine to enter your bloodstream. The immediate effects of smoking are irritation and redness in the lining of your nose and esophagus, dry mouth and bad breath since the tobacco components kill the good bacteria in your mouth. Once the nicotine is in your bloodstream, it stimulates your brain releasing feel-good chemicals. Within two hours, your body will have removed half the nicotine you have ingested. This means that after two hours, you are likely to have an urge to take another cigarette, and the cycle continues. 
When you ingest any product with nicotine, once it is in your body, it is broken down into more than 20 different substances. Some of these substances include cotinine, nornicotine, and anabasine, which are eventually excreted in the urine. Your body absorbs about 90% of nicotine from one cigarette, and even after the effects of nicotine have died down, traces of the substance will still be present in your body. This can be figured out by taking tests of one’s urine, blood, and saliva. Tests can also be done on the hair and nails to measure levels of nicotine and its by-products.
Cotinine levels in a smoker may take over two weeks to get back to normal, and it may take a while longer for nicotine levels in urine to decrease. As for traces of nicotine in the hair, it may take even longer for it to reduce. The period of time nicotine lasts in your body is dependent on several factors including how much smoking you do, age, and even gender. The levels of nicotine may last longer in individuals who are 65 years and older, and men may retain traces of nicotine longer than women since women tend to process nicotine faster than men.
Tobacco abuse has adverse effects on your overall health, and also results in addiction. There are various signs of addiction including craving cigarettes and withdrawal effects when you do not smoke. If you do note some of the indications of addiction, you should seek medical attention immediately. Nicotine gets into your system within 20 minutes and may last for 2 hours or more in your system depending on how often you smoke, one cigarette after the other.
