Chaotic dynamics have been studied by many researchers in the fields of biology, physics,and engineering. Interest in chaos is also expanding to the social sciences such as politics,economics, and others, including the prediction of societal events. The concept of leisure has developed from a passive concept correlated with relaxation, entertainment, and ideology formation into a positive concept that assumes a more active role. As information and communications technology develops, digital leisure activity is expected to continue spreading. This expansion of digital leisure function correctly, as well as. Traditional leisure activity functions correctly more, whereas digital leisure activity is predicted to function incorrectly more often. In this paper, we propose a mathematical addiction model of digital leisure that deals with its dysfunctions such as addiction to digital leisure, including computer games,internet search, internet chatting, and social media. Herein, to solve addiction to digital leisure,we propose a model derived from a nicotine addiction.
