Can nicotine free cigarettes be detected in a urine cotinine test? any help appreciated!

No: If you are not using nicotine in the heating chamber, and you haven't smoked tobacco in the last week, your test should be negative. I would point out that the safety of the propellant in these e-cigs (propylene glycol), as well as flavorings and additives, have never been subjected to study, and we simply do not know their long-term safety/dangers.They are likely safer than smoking tobacco though
