While it has been well documented that the subject of addiction psychology has an important place in the literature, various studies and research, especially in recent years, have shown that it is necessary to deal with the issue of addiction in an interdisciplinary context. This volume responds to this need, discussing addiction within the frameworks of psychology, health sciences and forensic sciences. It notes that results obtained through the collaboration of disciplines and application areas such as forensic sciences and medicine within the framework of psychology will enable academics and professionals develop a common ground and meet on it.
