Drug addiction can manifest itself as psychological, physical, or both. Psychological addiction refers to the subjective feelings the user requires in order to attain pleasure or euphoria. For instance, taking a drug in order to dull the pain of an unpleasant experience or to “relax” are examples of psychological dependence. Physical addiction, on the other hand, refers to the physiological effects of drug abuse and is characterized by withdrawal symptoms that are experienced when the user stops taking the drug. Tolerance is another aspect of physical addition. As a tolerance develops with continued use, the user needs to take increasing amounts of the drug in order to feel the initial “buzz” or “high.
Sadly, the persons who are actively involved in drug addiction are frequently the last ones to “see” their negative behavior and their own symptoms of addiction. When a person is addicted to drugs or alcohol, he or she no longer takes the substances to have fun or to get high. Rather, the addicted person needs the alcohol or the drugs in order to function on a daily basis. In many instances, the addicted person’s everyday life centers around satisfying his or her need for the substance on which he or she is hooked.
