Study Description

The main question it aims to answer are:

Obtain the effectiveness of combination of n-acetylcysteine and motivational enhancement therapy compared to a combination of motivational enhancement therapy and placebo on nicotine withdrawal symptom scores on nicotine addiction.

Obtaining the effectiveness of the combination of n-acetylcysteine and motivational enhancement therapy compared to the combination of motivational enhancement therapy and placebo on craving symptom scores on nicotine addiction.

Obtain the effectiveness of giving a combination of n-acetylcysteine and motivational enhancement therapy compared to a combination of motivational enhancement therapy and placebo in the incidence of abstinence in nicotine addiction.

Obtain the effectiveness of combination n-acetylcysteine and motivational enhancement therapy compared to a combination of motivational enhancement therapy and placebo on blood nicotine levels in nicotine addiction.

Obtain the effectiveness of combination n-acetylcysteine and motivational enhancement therapy compared to a combination of motivational enhancement therapy and placebo on n-acetylaspartate levels in the brain in nicotine addiction.

Obtain the effectiveness of combination n-acetylcysteine and motivational enhancement therapy compared to a combination of motivational enhancement therapy and placebo on glutamate levels in the brain on nicotine addiction.

Obtain an overview of nerve connectivity in nicotine addiction patient through post-therapy frontostriatal fMRI examination.

Evaluate the side effects and severe side effects of NAC administration on nicotine addiction.

Participants will:

Get blood testing for nicotine in 1st, 6th and 12th weeks Fill the QSU-Brief, MTWS questionnaire every 2 weeks for 12 weeks Get motivational enhancement therapy every 2 weeks for 12 weeks Get fMRI in the 12th week Consume 3600 mg n-acetylcysteine for 12 consecutive weeks (for treatment group) and placebo (for control group) Researchers will compare the laboratory, clinical and radiology improvement in both groups
