 The smoking frequency, and abstinence, will be assessed with a daily diary and exhaled carbon monoxide tests the CO2 tests will provide an objective confirmation of the abstinence reported in the diaries. The success the program will be compared based on the number of subjects who quitted or reduced their smoking frequency. The severity of addiction will be assessed with two questionnaires, the Fagerstrom and the Horn tests. Craving and withdrawal effects will be measured with the Minnesota Nicotine Withdrawal Scale MNWS and the Brief Questionnaire of Smoking Urges QSU-Brief at the baseline and at the visits from weeks 1 through 4, 6, 12 and at the end of the program. Before the VR immersion, the Immersive Tendencies Questionnaire will be administered and after each VR session participants will fill two questionnaires addressing presence and cybersickness. The comparative impact of both treatments will be tested with repeated measures ANOVAs and planned contrasts with sufficient power to detect medium effect sizes.
