It is important to distinguish psychological "addiction" from physical "dependence." Addiction refers to a psychological need and craving for drug effects that leads to continued use despite adverse impact on the user's life. Physical dependence means that the user experiences specific uncomfortable physical symptoms when deprived of the drug. Using these definitions, cocaine, amphetamines, opiates, alcohol, and nicotine are considered to be both addictive and dependence inducing. Marijuana and some other drugs are just addictive.
