Background: Drug abuse and its consequences place a considerable social and economic burden on society. Drug abuse has increased in Iran and reached three times the global average, indicating the need to develop innovative strategies to cope with this phenomenon. Objectives: Following a community-based participatory research approach, the aim was to identify the lived experience of drug users regarding the psychological aspect of their lifestyle. Methods: Narrative inquiry and phenomenological design were applied as the research framework. The use of in-depth interviewees and field notes guided the data collection and analysis. A total of 26 in-depth interviews were conducted with people who suffered from drug use (7 females and 19 males) in 2021. Interviewees ranging from 70 to 90 minutes were conducted in a quiet, private location chosen by the researcher. All interviews were audio-taped and transcribed, and analyzed using Colaizzi's method. Data analysis was administered using MAXQDA version 2020. Results: Most of the participants were educated Diploma and above. The participants' age ranged from 25 to 53 years old. During the interview, the subjects were in the following stages, methadone treatment time (n = 26). The analysis revealed four themes, and 11 sub-themes emerged. The themes were as follows: (1) negative emotions; (2) poor psychological capital; (3) poor support; and (4) psychological well-being. Conclusions: The most important problems of people with substance use, in the psychological dimension of lifestyle, include experiencing negative emotions, weak psychological capital, weak social support, unhealthy psychological well-being such as negative self-acceptance, reduced positive relations, not having a purposeful life, and inability to control environmental pressures. Hopefully, this study can help health policymakers develop more effective strategies against drug use.

Background: The aim of this study was to assess the effect of a training package based on the lived experience of substance abusers on sleep problems and mental health. Materials and Methods: The current study was performed on 70 subjects equally distributed into two groups of control and intervention, Data collection tools included the Pittsburgh Sleep Quality Index (PSQI), the General Health Questionnaire (GHQ), and the Basic Adlerian Scales for Interpersonal Success—Adult Form (BASIS-A) Inventory. Data analysis was administered using the independent t -test, paired t -test, and MANCOVA. Statistical significance was considered when the P value < 0.05. Results: A total of 70 subjects participated in this study; 7 (10.6%) were females and 59 (89.4%) were males, with a mean age of 36.29 ± 8.588 years. The total score of PSQI was 12.48 (±4.206) and 13.16 (±3.397) for control and intervention groups, respectively, and declined to 12.33 (±4.442) and 9.56 (±4.45) after the intervention. The intervention resulted in an improved score for scales of belonging, going along, taking charge, harshness, being liked by all, and striving for perfection. Whereas the total score of the GHQ is reduced for both groups, that in the intervention group showed a higher decrease, which was also statistically significant. Conclusion: The developed training package successfully improved participants’ sleep quality, mental health, and lifestyle.
