Nicotine dependence is a chronic addiction characterized by compulsive tobacco use despite harmful consequences. It is caused by nicotine's effect on dopamine receptors in the brain, creating physical dependence and withdrawal symptoms when use stops. The Nicotine and Cotinine LC/MS/MS Urine Test is the most important test for measuring tobacco exposure and monitoring cessation progress.
Nicotine dependence is caused by nicotine's powerful effect on the brain's reward system, specifically targeting nicotinic acetylcholine receptors that release dopamine and other neurotransmitters. When you smoke or use tobacco products, nicotine reaches the brain within seconds, creating feelings of pleasure and relaxation. With repeated exposure, your brain adapts to nicotine's presence by producing fewer dopamine receptors and reducing natural dopamine production, which means you need more nicotine to feel normal and experience withdrawal symptoms without it.
The Nicotine and Cotinine LC/MS/MS Urine Test is the most important test for nicotine dependence because it accurately measures both nicotine and its primary metabolite cotinine in your system. Cotinine is especially valuable because it remains detectable for 2-4 days after tobacco use, while nicotine itself only lasts a few hours, making cotinine a more reliable marker of tobacco exposure and usage patterns. This test uses advanced liquid chromatography-mass spectrometry technology to provide precise measurements that help healthcare providers assess the severity of tobacco use, verify smoking status, and monitor progress during quit attempts. The quantitative results show actual levels rather than just positive or negative, giving you and your doctor detailed information to guide treatment decisions.
You should get tested if you are starting a smoking cessation program and want to establish a baseline of your tobacco use, if you need to verify your smoking status for insurance purposes or workplace requirements, or if you want objective feedback on your progress during a quit attempt. Testing is also valuable if you are using nicotine replacement therapy and want to ensure you are getting appropriate nicotine levels without relapsing to cigarettes, or if your healthcare provider needs to assess your tobacco exposure to guide treatment decisions. Regular testing during cessation can provide motivation and accountability as you see your levels decrease over time.
What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
