Considering the Definition of Addiction

For example, people detoxing from heroin are often given a longer-acting opioid like methadone or buprenorphine to alleviate withdrawal symptoms and cravings. Detox is a relatively short-term process lasting several days to several weeks that helps drug abusers safely stop taking drugs while avoiding dangerous withdrawal symptoms.

While the drug addiction definition process is a necessary step towards recovery, detox does little itself drug addiction definition treat addiction in the long term.

Research has shown that individuals who do not participate in drug treatment programs after undergoing detox are likely to relapse and end up needing detox again in the future 5. Just as some drugs that drug addiction definition dependence are not addictive, there are also highly addictive drugs that do not produce physical withdrawal symptoms.

Even after long periods of abuse, psychostimulant drugs, including cocaine and methamphetaminedo not produce pronounced physical withdrawal symptoms like vomiting and shaking, although there can be psychological symptoms such as depression, anxiety, and drug cravings drug addiction definition.

Addiction as a Disease

Current neuroscience drug addiction definition that the neurocircuitry of reward also involves a rich bi-directional circuitry connecting the nucleus accumbens and the basal forebrain.

It is the reward circuitry where reward is registered, and where the most fundamental rewards such as food, hydration, sex, and nurturing exert a strong and life-sustaining influence. Alcohol, nicotine, other drugs and pathological gambling behaviors exert their initial effects by acting on the same reward circuitry that appears in the brain to make food and sex, for example, profoundly reinforcing.

Other effects, such as drug addiction definition and emotional euphoria from rewards, derive from activation of the reward circuitry.

Addiction: Definition, symptoms, withdrawal, and treatment

While intoxication and withdrawal are well understood through the study of reward circuitry, drug addiction definition of addiction requires understanding of a broader network of neural connections involving forebrain as well as midbrain structures.

Although these characteristic features are widely present in most cases of addiction, regardless of the pharmacology of the substance use seen in addiction or the reward that is pathologically pursued, each feature may not be equally prominent in every case.

A final limitation is that we did not place emphasis on the knowledge that addiction may be context-dependent.

That is, what is considered an addiction in one social-environmental location may not drug addiction definition considered addiction in another location [ 27 ]. For example, daily use of marijuana may be considered an addiction in the United States but not in some settings in Jamaica.

Likewise, at a more specific level of inquiry, the five definitional elements offered herein drug addiction definition engagement, preoccupation, satiation, loss of control, and negative consequences may vary in application in different social-environmental locations.

It is likely that more extreme levels of each of these elements would drug addiction definition considered definitive of addiction when examining marijuana use in settings in Jamaica in comparison to the US; that is, it may be difficult to remove addiction and its defining elements from varying normative standards of behavior.
