What Do Results Mean? If your levels of nicotine are moderate, it might mean you used tobacco and stopped about 2 to 3 weeks before the test. It's possible for people who don't use tobacco to test positive for a low level of nicotine if they're exposed to tobacco smoke in their surroundings.
False Positive Testing
Although, being exposed to frequent or very high levels of secondhand smoke may cause someone to test positive for nicotine use.
Those who do not use tobacco may test positive for cotinine because of passive exposure to cigarette smoke.
Nicotine is the addictive substance in tobacco, cigarettes, and vapes or e-cigarettes. When people use tobacco products, some of the nicotine stays in their system after they quit smoking. Medical tests can detect nicotine in people's urine, blood, saliva, hair, and nails.
Test Results Meaning
However, if you have about 10 ng/mL of nicotine in your system, it may confirm your tobacco use within the detection window.

After 15 years of having quit smoking, the likelihood of developing coronary heart disease is the equivalent of a non-smoker. Similarly, the risk of developing pancreatic cancer has reduced to the same level as a non-smoker.
Blood testing
There are several tests that can be used to measure cotinine levels. Blood testing is very accurate and can detect both nicotine and cotinine. It's also the most expensive and invasive testing method, so it's less frequently used than the other methods.
Following design of studies, plasma nicotine Cmax was observed between 0 and 5 ng/mL (no significant changes) or between 13.9 and 16.3 ng/mL (similar to a tobacco cigarette) with a Tmax between 70 and 75 minutes. Cotinine levels after “vaping” an e-cigarette are similar to a tobacco cigarette.
The most obvious way to pass a nicotine drug test is to avoid nicotine altogether. If you're a smoker, consider quitting or taking a break from smoking before the test. Avoid nicotine replacement products, such as gum or patches, as they can also cause a positive result on a nicotine drug test.
Nonsmoking is usually defined as a serum cotinine level of less than or equal to 10 ng/mL (Pirkle et al., 1996).
Cotinine is a product formed after the chemical nicotine enters the body. Nicotine is a chemical found in tobacco products, including cigarettes and chewing tobacco.
On average, about 70 to 80 percent of nicotine is converted to cotinine, which is the main proximate metabolite. Most studies of nicotine intake from cigarettes producing different yields have used cotinine as the marker of nicotine intake.
Water helps flush nicotine and other chemicals out of your body. Therefore, drinking water in sufficient quantities is a must for every smoker. However, it will make you urinate more often. Frequent urination is helpful because nicotine, cotinine and most tobacco toxins are removed from the body through urine.
Cotinine is an alkaloid found in tobacco leaves and the main metabolite of nicotine. The active form of cotinine, the isomer S(-)-cotinine accumulates in the body after tobacco consumption. The pharmacokinetic profiles of cotinine administered orally or intravenously have been investigated in humans.
Cotinine is a minor tobacco alkaloid and the major metabolite of nicotine. It is most commonly used as a biomarker for nicotine exposure (Benowitz and Jacob, 1994; Zhu et al., 2013).
How Long Does Vape Stay in Urine? Nicotine can last up to 4 days in urine, but testing can still detect a small amount of cotinine up to 3 weeks after your last exposure. Cotinine levels in a regular vaper may measure 30 to 50 ng/mL, while those who have secondhand exposure may still pick up less than 1 ng/mL.
As little as two or three days after your last time vaping or smoking a cigarette, you will essentially have no detectable nicotine remaining in your system. For that reason, drug tests generally don't check for nicotine.
The mean (±SD) urinary cotinine levels were determined as 1755 ± 1848 ng/g creatinine for 32 e-cigarette users, 1720 ± 1335 ng/g creatinine for 33 cigarette smokers and 81.42 ± 97.90 ng/g creatinine for 33 passive smokers.
Parents may smell odors if a child is vaping in the bathroom or bedroom, and they may spot symptoms if their child vapes a synthetic drug, he added. “Parents may also notice generalized symptoms of vaping, such as mouth sores or infections, chronic respiratory inflammation and dry eyes,” he said.
There are several tests available that can detect vaping/nicotine use and there is no need to see a doctor first. Hair Follicle Test – This is a good option for parents who think their child has been either vaping or smoking nicotine for a long period of time and the child might stop using just to get through the test.
The Benefits of Quitting
Additionally, quitting vaping will improve your blood circulation and enable your lungs to begin healing. This will result in fewer coughing episodes and improved breathing ability during physical activity.
Lung function starts to improve 2 weeks to 3 months after quitting. From 1–12 months after quitting, symptoms such as coughing and breathing problems should improve as lung structures heal. If people wish to quit vaping, they can speak with a healthcare professional.
After seven days without smoking, you will have higher levels of protective antioxidants such as vitamin C in your blood. After a week without smoking, nerve endings damaged by smoking will start to regrow so you may start to notice you have more ability to taste and smell.
