      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Randomization will be done based on the method of random block permutations. Random sequence generation software is used, which refers to the method used to perform a random sequence on the participants in the study, so that the assigned group is not known before assigning the individual. By using sealed opaque mail envelopes with a random sequence, each of the generated random sequences is recorded on a card and the cards are placed inside the mail envelopes in order. In order to maintain the random sequence, the outer surface of the envelopes is numbered in the same order. Finally, the lid of the letter envelopes is glued and placed in a box. At the time of starting the registration of participants, based on the order in which eligible participants entered the study, one of the envelopes will be opened and the assigned group of that participant will be revealed.Based on the method of the permutation blocks of size 4, individuals are randomly divided into two groups. According to that, there are 2 treatments, for every block a different random order will be prepared. Random table was used as the randomization tool, Blinding description: In this study, the project manager and the patient are unaware of which of the two groups will receive which drug or placebo. Medicines and placebos will be similar in terms of shape, color, smell and taste.</study_design>

      <i_freetext>Intervention 1: Intervention group: In addition to methadone as the main treatment, patients in the intervention group will receive 220 mg zinc sulfate capsules every other day for three months. The dose of this capsule will not change during the study period. This pill will be prepared from Aria Pharmaceuticals. Intervention 2: Control group: In addition to methadone as the main treatment, patients in this group will receive placebo capsules every other day for three months. Medicines and placebos will be similar in terms of shape, color, smell, and taste. This pill will be prepared under the supervision of the Faculty of Pharmacy of Ahvaz University of Medical Sciences.</i_freetext>
