TYPES OF ADDICTION
TYPES OF ADDICTION
Substance addiction is a progressive, relapsing condition that is characterized by compulsive alcohol or drug use despite negative consequences Addiction significantly impairs the user’s ability to control or quit substance abuse. Two mechanisms that fuel substance addiction are tolerance and dependence. Someone who has developed tolerance to a substance requires increasing doses to feel the desired effects. Taking ever-increasing doses or taking them more frequently to overcome tolerance can speed up the development of dependence. When someone is dependent on a drug, they need the drug just to feel normal and will often experience some form of withdrawal when use is cut back or stopped.
