The opioid crisis brought increased attention to the issue of addiction, but the disorder has impacted many lives since long before the current addiction crisis. This volume examines addiction from a psychological, biochemical, and medical perspective to give readers a better understanding of how addictions form, what sustains them, and ways in which people recover from them. It considers not only addiction to substances like drugs and alcohol, but behavioral addictions as well, such as internet addiction, gambling, and binge eating. Readers will also become more familiar with the latest advancements in the treatment of addiction as well as lifestyle choices that impact addiction.
