At 1 month, 8 persons of group 2 (21.62%) and 22 persons of group 1 (55%) were able to stop smoking. At 3 months, 8 persons of group 2 (21.62%) and 17 persons of group 1 (42.5%) were still abstinent. At 6 months, 7 persons of group 2 (18.9%) and 14 persons of group 1 (35%) were able to stop smoking. At 12 months, 5 persons of group 2 (13.5%) were able to maintain their abstinence.
