Psychological addiction, as opposed to physiological addiction, is a person's need to use a drug out of desire for the effects it produces, rather than to relieve withdrawal symptoms. Heroin, for example, produces a physical dependence; the drug eventually takes the place of natural endorphins, so that addicts may use heroin simply to reduce pain. Other drugs, like marijuana, do not create a physical dependency. However, one may become psychologically addicted if he/she comes to depend upon the drug's effect as part of normal existence.
Some doctors make little distinction between the two types of addiction, for the result —substance abuse— is the same. The cause of the addiction in either case is much different, though, as is the type of treatment preferred.
Addiction is a compulsion to repeat a behavior regardless of its consequences.
Psychologicaladdictions are a dependency of the mind, and lead to psychological withdrawal symptoms.
It is frequently noted that certain addictions "run in the family," and while researchers continue to explore the extent of genetic influence, there is strong evidence that genetic predisposition is often a factor in dependency.
Addiction is a chronic disorder proposed to be precipitated by a combination of genetic, biological/pharmacological and social factors.
Addictions can theoretically form for any rewarding behavior, or as a habitual means to avoid undesired activity, but typically they only do so to a clinical level in individuals who have emotional, social, or psychological dysfunctions, taking the place of normal positive stimuli not otherwise attained (see Rat Park).
Psychologicaladdiction, as opposed to physiological addiction, is a person's need to use a drug or engage in a behavior despite the harm caused out of desire for the effects it produces, rather than to relieve withdrawal symptoms.
