Addiction is a persistent, compulsive dependence on a behavior or substance. The term has been partially replaced by the word dependence for substance abuse. Addiction has been extended, however, to include mood-altering behaviors or activities.
What is Addiction? When a drug user can't stop taking a drug even if he wants to, it's called addiction. The urge is too strong to control, even if you know the drug is causing harm. When people start taking drugs, they don't plan to get addicted. They like how the drug makes them feel.
