Hair test: Hair tests are reliable for long-term detection, showing nicotine use for one to three months. In some cases, nicotine can be detected for up to 12 months. In some cases, nicotine can ...
The Fagerström Test for Nicotine dependence is a standard instrument for assessing the intensity of addiction to nicotine. It evaluates the quantity of cigarette consumption, the compulsion to use, and dependence. In addition to this, the DSM-5 for tobacco use disorder can be used by physicians and nurse practitioners to make a diagnosis.
The CRAFFT 2.1 screening tool begins with past-12-month frequency items (Part A), rather than the previous "yes/no" question for any use over the past year, and the other six (Part B) questions remain the same. The CRAFFT can function as a self-report questionnaire or an interview to be administered by a clinician. [2]
While many of these employers are using the honor system to enforce these policies, a few of them are requiring that employees be tested for nicotine. [citation needed] Many of the businesses with these policies are in the healthcare industry, but some county and municipal governments have also enacted such policies. [2] [3]
The proposed rule doesn't ban nicotine but lowers the amount allowed in cigarettes, cigarette tobacco, roll-your-own tobacco and most cigars to 0.7 milligrams per gram of tobacco − a smaller ...
Cotinine: Cotinine, a metabolite of nicotine, is present in smokers. Like carbon monoxide, a cotinine test can be a reliable biomarker to determine smoking status. [114] Cotinine levels can be tested through urine, saliva, blood, or hair samples. One of the main concerns of cotinine testing is the invasiveness of typical sampling methods.
Cotinine has an in vivo half-life of approximately 20 hours, and is typically detectable for several days (up to one week) after the use of tobacco. The level of cotinine in the blood, saliva, and urine is proportionate to the amount of exposure to tobacco smoke, so it is a valuable indicator of tobacco smoke exposure, including secondary (passive) smoke.

The chart depicts the longer detection times of the metabolites. In the case of hair testing, the metabolytes are permanently embedded into hair, and the detection time is determined by the length of the hair sample used in the analysis. The standard length of head hair used in the test is 1.5", which corresponds to about 3 months.
