[**] OLS estimation produces similar estimates to the ML estimates presented here, however, ML estimation is preferred due to its robustness to distributional assumptions regarding the error term

There is currently no international standard for quantifying the nicotine inhaled with heated tobacco products, which leaves a gray area exploited by the manufacturer in the information provided to consumers

NRT Traditional Cigarettes: Highest cotinine levels Longest detection times Additional compounds extend window 4,000+ chemicals affect metabolism Vaping/E-cigarettes: 30% lower cotinine than cigarettes Slightly shorter detection Depends on nicotine concentration 3mg = light use, 50mg = heavy use Nicotine Pouches (Zyn, Velo, etc.): Similar to vaping timelines Consistent dosing = predictable clearance 3mg pouch light cigarette 6mg pouch regular cigarette Nicotine Replacement (Gum, Patches): Lower, steadier cotinine levels Can extend detection paradoxically Patches = longest detection of NRT Gum = shorter bursts, faster clearance The Factors That Can Double Your Detection Time Biological Factors You Can't Control Age: Metabolism slows 2-3% per decade after 30 Gender: Women clear cotinine 10% faster (estrogen effect) Genetics: 5-10% are "slow metabolizers" (CYP2A6 gene variant) Race: Some studies show variations in metabolism rates Pregnancy: Clearance increases by 60% (but don't start while pregnant) Lifestyle Factors You Can Control Exercise: Regular cardio speeds clearance by 15-20% Diet: High-fiber, antioxidant-rich foods help Hydration: 8-10 glasses daily optimizes kidney function Sleep: Poor sleep slows all metabolic processes Medications: Some drugs slow nicotine metabolism The Medications That Mess With Your Timeline Slow clearance: Antifungals (ketoconazole) Some antidepressants Blood pressure medications Birth control pills Speed clearance: Phenobarbital Rifampin Some antibiotics How to Speed Up Nicotine Clearance (Evidence-Based Methods) What Actually Works 1
