Few scientific studies evaluate the pharmacological and non-pharmacological measurement of pulmonary age for smoking cessation. Moreover, existing research studies provide contradictory results. DESCRIPTION OF THE RESEARCH METHODOLOGY Experimental design Cluster randomized controlled trial on the center (= medical practices) in 2 parallel groups (intervention group (pulmonary age estimation) and control group (no pulmonary age estimation)). National multicentric research: 33 participating centers (= medical practices), located in Ile de France and Provence Alpes Côte d'Azur (PACA). 4 referring physicians (=regional coordinators) were identified to energize the team of investigators and facilitate inclusions. There are 3 in Ile de France and 1 in PACA. Randomization General practitioners who agree to participate in this study will be randomized according to a computerized procedure and centralized in 2 groups (=randomization in a cluster on the center (medical office)): a group providing routine smoking cessation management (control group), which will not receive any specific guidance on the means to be used in this management. a group providing routine smoking cessation management, accompanied by estimation and communication to the patient of the pulmonary age, measured using a PulmoLife electronic device. (Intervention Group) Consenting patients will then receive smoking cessation assistance from their physician according to the randomization arm in which the physician is assigned (usual versus usual management + pulmonary age estimate and patient information). Patients will be called to the doctor's office 6 months later to measure the expired CO and complete a questionnaire on their tobacco consumption. RESEARCH PROCESS Patients will be invited to participate in the study by the general practitioner during a consultation, regardless of the reason for the consultation (tobacco-related or not) Inclusion visit (M0) During this visit, the inclusion and non-inclusion criteria will be verified. The general practitioner will present the study to the patient in detail (an information note on the study will have been given to him/her beforehand in the waiting room). If the patient agrees to participate in the study, his or her informed and written consent will be obtained. The information collected by the general practitioner will be: socio-demographic data: age, sex, family situation, level of education, occupation, health insurance coverage (yes/no) overall health and co-morbidities smoking history: age of smoking onset, current number of cigarettes per day, average number of cigarettes since smoking began the number of withdrawal attempts, the maximum duration of withdrawal, the methods used, the date of the last attempt nicotine dependence (short Fagerström test), motivation to stop (Prochaska) chronic pathologies other addictions: collection of cannabis consumption respiratory symptoms (GOLD-CNAM questionnaire) overall health status (EQ-5D questionnaire) measurement of expired CO set of spirometric data from Pulmolife (FEV1, pulmonary age) (only for the "intervention" group) (= pulmonary age estimate) It should be noted that whatever the group, the doctor will follow the patient according to current recommendations and his usual practice of managing smoking cessation. 6-month follow-up visit (+/- 15 days) (M6) This visit will take place in both groups, 6 months +/- 15 days after the patient's inclusion. During this visit, the doctor will collect: current smoking status (over the last 15 days) the measurement of expired CO the number of withdrawals attempts since inclusion, the duration of the attempts, the average number of cigarettes per day over the period the withdrawal assistance methods used during the period respiratory symptoms (GOLD-CNAM questionnaire) overall health status (EQ-5D questionnaire) intercurrent events set of spirometric data from Pulmolife (FEV1, pulmonary age) (only for the "intervention" group) (= pulmonary age estimate) Telephone contact at 12 months (+/- 15 days) (M12) During this telephone contact (which will be made in the 2 groups of patients), will be collected by the doctor: Global health status data (EQ-ED) smoking status (over the last 15 days) the number of withdrawals attempts since inclusion, the duration of the attempts, the average number of cigarettes per day over the period the withdrawal assistance methods used during the period respiratory symptoms (GOLD CNAM questionnaire) intercurrent events This telephone contact will correspond to the end of the patient's participation in the study. EFFECTIVENESS EVALUATION Description of efficacy evaluation parameters The parameters for evaluating the effectiveness of the intervention are: Smoking cessation rate at 6 months from the intervention. Smoking cessation will be confirmed by measuring the exhaled CO at a scheduled 6-month follow-up consultation with the general practitioner Persistence of withdrawal at 12 months assessed by patient questionnaire: persistence of smoking cessation yes/no Smoking cessation rate at 12 months Characteristics of smoking cessation evaluated by questionnaire/patient: Smoking cessation yes/no, if no: reduction in tobacco consumption yes/no and number of cigarettes smoked per day at M6 versus M0 Older smoking cessation for patients who have quit smoking Number of smoking cessation attempts within 6 months of the intervention and pharmacological and non-pharmacological measures implemented, including the use of alternative therapies (hypnosis, acupuncture, auriculotherapy, relaxation, etc.) Satisfaction of general practitioners measured by a satisfaction score on a Likert scale from 1 to 10
