Drug abuse and drug addiction are becoming growing issues in most countries worldwide and are considered major public health problems. An initiative has been introduced in Malaysia via the methadone maintenance treatment program since the year 2005. Although the program has shown gradual success over the years by reducing the relapse rate of the patients, it has encountered several challenges in maintaining the effectiveness of the manual dispensing method done by the authorized health practitioners. Therefore, an automated methadone dispenser was developed to improve the effectiveness and comply with the requirements and needs of the users. In this research, the reliability and feasibility of the dispenser were determined through percentage error, accuracy and efficiency, and tests, respectively. Based on the performance evaluation, the findings suggested that the automated methadone dispenser has contributed to the decrease of percentage error to 3.42 %, 31.52 % higher accuracy, and 96 % better efficiency compared to current manual methadone dispensing practices.
