Abstract By looking at drug addiction from an evolutionary perspective we may understand its underlying significance and evaluate its three-fold nature biology psychology and social influences. In this investigation it is important to delve into the co-evolution of mammalian brains and ancient psychotropic plants. Gaining an understanding of the implications of ancient psychotropic substance use in altering mammalian brains will assist in assessing the causes and effects of addiction in a modern-day context. By exploring addiction in this manner we may move towards more effective treatment early prevention treating the root of the issue rather than the symptoms. 1.
