Social support is an important aspect of the drug recovery process and helps prevent a person from re-engaging with relapse addiction. Therefore, this research was conducted to (1) identify the level of social support among drug offenders and (2) analyze the relationship between social support with high-risk relapse situations among drug offenders. The study was conducted using a cross-sectional survey using a quantitative design. A total of 407 prisoners involved in drug cases and undergoing detention and rehabilitation at Jabatan Penjara Malaysia (The Malaysian Prisons Department) were selected as study respondents. The data collected were analyzed using descriptive and Pearson correlation tests. The study results show that the majority of drug offenders undergoing rehabilitation and detention in Malaysian prisons receive social support at a moderate to high level. Pearson correlation analysis found that social support had a significant relationship with high-risk relapse situations. The research results have implications for stakeholders in improving more effective drug treatment and rehabilitation programs with the involvement and social support from family, friends and the local community.
