Brief summary

The purpose of this study is to study the impact of smoking in the preceding hours before a bronchoscopy on the tolerance of this exam.

Detailed description

Tolerance evaluation of the bronchoscopy on current and regular smokers. The investigators assess episodes of cough, dyspnea, volume of lidocain (liquid 1% and in spray 10%), duration of the procedure, episodes of desaturation and completion of the bronchoscopy. The investigators compare patients who did not smoke in the 6 hours before the bronchoscopy and those who have smoked.
