Background and Aim: Distance learning techniques are gaining popularity as the internet today is a faster and more convenient source of spreading exhaustive information. We aim at conducting a scoping review on the utility of internet-based learning in addiction psychiatry. Methods: We performed a systematic search of databases such as Google Scholar, PubMed, and Cochrane using the following keywords: Distance education, substance related disorder, teaching, internet, along with the MeSH terms (“Internet” AND “Teaching” AND “Substance Related Disorders”) OR (“Distance Education” AND “Substance Related Disorders”). The reference lists of articles were searched for other relevant literature. Results: A total of 34 studies were included. Most of the courses offered online were on specific therapies, for example, training on motivational interviewing, twelve-step facilitation, cognitive behavioral therapy, alcohol screening, and brief intervention. They were based on various aspects of distance learning such as the acquisition of knowledge or skills, feasibility, level of satisfaction of the trainees/students, the cost-effectiveness of the techniques, and the type of trainees who have access to the course. The majority of the studies showed positive findings in terms of the parameter being studied. However, the level of satisfaction among the students is questionable. Conclusion: Internet-based teaching programs provide a good alternative to traditional educational methods in terms of effectiveness, feasibility, and acquisition of knowledge and skills. We emphasize the use of internet-based training in addiction psychiatry reinforced by actual practical experiences.
