Direct Transcranial Electrical Stimulation in Tobacco Addiction (tDCS)

Study Overview
=================
Brief Summary
-----------------
In summary, there are currently many therapeutic tools for achieving some degree of control or even cessation of tobacco addictive use. No single therapy seems to have proven itself sufficiently effective to be the preferred treatment axis in the management of this addiction. We can also point out that so far the main treatments aimed at reducing or controlling the craving phenomenon are of a pharmacological nature, thus exposing the participants to the side effects inherent to this type of treatment. In this perspective, the establishment of non invasive brain stimulation (TdCS), acting in a targeted manner on craving and whose effects would be mild and transient, appears quite justified, especially in addition to psychotherapy. In the context of the management of addictive pathologies, the choice of smoking dependence seems relevant to us insofar as this addiction represents a major public health problem.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Fagerström score (3 is the highest score and O the lowest one for item 1. A score of 1 or 2 means low dependence (for item 1 only as well as if you use the total score) | average difference in Fagerström score 1 scores that assess craving for tobacco between pre-treatment assessment (J0) and short-term post-treatment evaluations (J15). | 15 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| tobacco consumption | Evaluation of changes in tobacco consumption and smoking craving intensity and tolerance of tDCS | 15 days |
