Hormones can influence drug addiction-A narrative review.

Drug addiction is a dangerous condition that is the concern of human societies. Nevertheless, several issues exist ahead of people with a drug use disorder during addiction. Accordingly, various types of studies have been conducted to understand better the problems that people with a drug use disorder encountered. People with a drug use disorder usually have a problem tolerating the withdrawal period and some relapse to drug abuse. Complementary studies further revealed that some hormones like oxytocin (OXT), vasopressin, hypothalamic-pituitary-adrenal axis (HPA) axis hormones, sex hormones, thyroid hormones, and nutritional hormones are probably involved in addiction processes. These hormones completely with different mechanisms can influence drug users' ultimate outcome. As we will see, these hormones influence tolerance, sensitization, and compulsive drug seeking and taking behavior. In this review, they have been further discussed.
