Can 'vaping' (e-cigerettes) with nicotine in a propylene glycol solution cause elevated liver enzymes. Not sure if nicotine has an effect on liver? Ty
No: Nicotine has no adverse effect upon the liver unless you had a major overdose which only happens with the administration of large doses of nicotine. These doses cannot be met by smoking or vaping. Propylene glycol won't cause problems either. I would worry about chronic lung damage and nicotine addiction. If your liver enzymes are elevated, your doctor needs to find out the reason. ...Read more
2-3 days: For most smokers. After a single exposure to tobacco smoke, cotinine can be detected in blood or urine for less than 24 hours, but in an individual smoking 1/2 pack or more per day, 2-3 days is common. It is rarely positive after 5 days. Hair testing can detect cotinine (main metabolite) for months, depending on length of hair. Nicotine is very short-acting and is only present for hours. ...Read more

2-3 days: nicotine is a very short-acting drug, and its main metabolite cotinine is too. After a single cigarette, levels will usually only be detectable for 24 hours, and most regular smokers will be detectable for 3 days or so.

Doesn't accumulate: Really doesn't matter that much if you are a heavy or light user. Nicotine is a very short-acting chemical and is only active in bloodstream for a few hours, then is converted to a metabolite cotinine that is metabolically inactive, but is what most drug tests look for. It sticks around in blood for 1-2 days, in urine for 2-4 days, oral swabs can pick it up a little longer, perhaps 3-5 days. ...Read more
