Contemporary research in neurobiology (a branch of science that deals with the anatomy, [9] physiology, and pathology of nervous system) of addiction points to genetics as a major contributing factor to addiction vulnerability. It has been estimated that 40–60% of the vulnerability to developing an addiction is due to genetics.
The impact factor relates to a specific time period; it is possible to calculate it for any desired period. For example, the JCR also includes a five-year impact factor, which is calculated by dividing the number of citations to the journal in a given year by the number of articles published in that journal in the previous five years.

Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption ...
The Addiction Severity Index (ASI) is used to assess the severity of patient's addiction and analyse the need of treatment which has been in use for more than 2 decades since its publication in 1992. It is used in a variety of settings such as clinics, mental health services in the US, the Indian Health Service and several European countries ...
A number of genetic and environmental risk factors exist for developing an addiction. [3] [93] Genetic and environmental risk factors each account for roughly half of an individual's risk for developing an addiction; [3] the contribution from epigenetic risk factors to the total risk is unknown. [93]
[2] The TOP Guidelines provide structure to research planning and reporting and aim to make research more transparent, accessible, and reproducible. [3] The journal includes articles on the following topics: alcohol and alcoholism; drug use and abuse; eating disorders; smoking and nicotine addiction, and
Addiction Biology is a quarterly peer-reviewed scientific journal covering research on substance abuse. It is one of two journals published on behalf of the Society for the Study of Addiction to Alcohol and other Drugs. The major focus of Addiction Biology is on neuroscience contributions from animal experimentation and clinical point of views.
It attributes addiction to a chemical imbalance in an individual's brain associated with genetics or environmental factors. [ 3 ] The other model is the choice model of addiction , which contends that addiction is a result of voluntary actions rather than brain dysfunction. [ 4 ]
