SUMMARY
During rehabilitation and withdrawal, drug users often feel worried about the future, fear that they will be rejected by society and their families, and feel guilty about themselves and God. This concern causes drug users to feel negative emotions and feelings of discomfort. This study was conducted to see the effectiveness of dhikr therapy to increase peace of mind in drug users who are undergoing rehabilitation. Eight former drug users were involved in this study. Subjects were divided into two groups, namely the experimental group (n = 4) and the control group (n = 4). The research design used was a pre-test post-test control group design and was measured three times (pre-test, post-test, and two-week follow-up). The measuring instrument used in the study is Tatmain al-Qulub (TQS) by Rusdi (2016) which is arranged based on aspects of peace of mind. The results of this study found that there was a significant increase in peace of mind in drug users after being given dhikr therapy.
