Substance addiction remains a significant social and medical issue, influenced by both environmental and genetic variables. The interplay between genetic and ecological factors demonstrates the importance of the epigenetic mechanism. Given its ability to control and influence enduring alterations in gene expression, epigenetic regulation provides a compelling hypothesis for the persistent behavioral abnormalities associated with drug addiction. Epigenetic mechanisms, including DNA methylation, significantly influence drug addiction and substance abuse. Environmental factors such as parental influence, cultural norms, media representation, and learned physical associations also contribute to addiction. Nutritional, pharmacological, physical, and psychosocial factors (such as stress exposure) also affect the DNA methylation profile, leading to changes in gene expression and vulnerability to drug addiction. Studies show that genetic predispositions to psychiatric illnesses like addiction vulnerability can be attenuated or regulated by environmental factors. This chapter will focus on the effect of DNA methylation and environmental factors on drug addiction. Understanding these variables could potentially provide interpretive tools for the future diagnosis and management of addiction.
