Determination of Carcinogens Nicotine in Electronic Cigarettes Users (CANICE)
Smoking, Carcinogenesis of the Nicotine
About this trial
This is an interventional prevention trial for Smoking focused on measuring urinary N'Nitrosonornicotine, nicotine, electronic cigarette, nicotine remplacement treatment

- Using a nicotine dosage of 12mg / ml or more for at least 4 weeks
- Former smokers who consumed 10 cigarettes per day or more
- Having completely stopped smoking for at least 4 weeks
- No Subjected to passive smoking (verified by measuring carbon monoxide in exhaled air)
- With health insurance
Group 3:
- Adults (18 years old and more)
- People in patch 21 mg / 24h or 25mg / 16h in the fourth week or more treatment
- Without taking oral nicotine or electronic cigarette for at least 4 weeks
- Not subject to passive smoking (verified by measuring carbon monoxide in exhaled air)
- Former smokers who consumed 10 cigarettes per day or more
- Having completely stopped smoking for at least 4 weeks

Group 4 (control group):
- Adults (18 years old and more)
- People Non-smoking, non-users of electronic cigarette, non-users of nicotine replacement therapy for at least 4 weeks
- Not subject to passive smoking (verified by measuring carbon monoxide in exhaled air)
- With health insurance
Patients in Groups 1, 2 and 3 must have a urinary cotinine ≥ 100 (ratio cotinine / creatinine - Determination Cotinine DRI). Patients in group 4 must have a urinary cotinine ≤ 10 (cotinine / creatinine ratio - Determination Cotinine DRI)
The thresholds of carbon monoxide from clinical experience are:
- Non current smoker: 0 to 5 parts per million (ppm)
- Passive smoker: 6 to 9 ppm
- Current active smoker : 10 ppm or more
Non inclusion criteria
- Rolling tobacco, cigars, cigarillos, pipe, bidi, chicha, cannabis smockers during the last 4 weeks
- Users tobacco snuff or chewing tobacco during the last 4 weeks
- Users of oral nicotine replacement therapy (gum, lozenges, inhalers, oral spray) during the last 4 weeks.
- Users of drug for smoking cessation aid other than nicotinic treatment: Varenicline, Bupropion, clonidine, Cytisine during the last 4 weeks
- Pregnant or breastfeeding women
- Non-compliant or unable to follow directions
- Refusing to sign the informed consent
- Refusing to do the urine collection
- Under guardianship or any other protective measures
Exclusion Criteria:
Group 1, 2 and 3:
-Having an urinary cotinine <100 (ratio cotinine / creatinine - Determination Cotinine DRI)
Group 4 (control group):
- Having an urinary cotinine> 10 (ratio cotinine / creatinine - Determination Cotinine DRI)
The determination of urinary cotinine levels will be carried out centrally. The result will not be available at the inclusion visit. The included patients who do not have the urinary cotinine levels required for their group, will secondarily excluded from the study.
The number of subjects in Groups 1, 2 and 3 with a ratio of cotinine would be less than 100 is expected to be negligible.A102
