Effect of Transcranial Direct Current Stimulation (tDCS) on Tobacco Consumption

The primary purpose of the protocol is to evaluate the effect of repeated application for 5 consecutive days of a real tDCS compared to the application of a placebo tDCS (sham procedure) on the evolution of tobacco consumption in the short term between Day 1 and Day 5. The study hypothesis is that a repeated application for 5 consecutive days of a real tDCS on the left dorsolateral prefrontal cortex region will reduce the craving induced causing a decreased of daily tobacco consumption between Day 1 and Day 5 which can persist at the final visit between Day 15 and Day 20.
