Alcohol/Drug addiction refers to the dependence on psychoactive substances that provides a pleasurable experience to the brain and has the potential of psychological dependence along with physical dependence. Dependence on drugs/alcohol is destructive as it causes an immense craving for consuming the drug. When the drug is unavailable, experiencing nausea, vomiting, sweating, body trembling, shaking, diarrhoea, forgetting things, hallucinating are common withdrawal symptoms. Chronic drug/alcohol uses disturbs the natural functioning and adversely bring changes in the functioning of the brain.
According to ICD-10 (International Classification of Diseases) if three or more of the following have been present together at some time during the previous year.
- A strong desire or sense of compulsion to take the alcohol/drug;
- Difficulties in controlling substance-taking behaviour in terms of when to start, stop and how much quantity to take.
- A physiological withdrawal state when alcohol/drug use has ceased or have been reduced, or use of the same (or closely related) alcohol/drug with the intention of relieving or avoiding withdrawal symptoms;
- Evidence of tolerance, such that increased doses of the alcohol/drug are required in order to achieve effects originally produced by lower doses (clear examples of this are found in alcohol- and opiate-dependent individuals who may take daily doses sufficient to incapacitate or kill non-tolerant users);
- Progressive neglect of alternative pleasures or interests because of alcohol/drug use, an increased amount of time necessary to obtain or take the substance or to recover from its effects;
- Persisting use of alcohol/drug despite clear evidence of overtly harmful consequences, such as harm to the liver through excessive drinking, depressive mood states consequent to periods of heavy substance use, or drug-related impairment of cognitive functioning
