Mid-16th century of the obsolete adjective addict 'tied or devoted (to someone'), from the Latin addict- 'assigned', from the verb addicere, from ad- 'a' + dicere 'say'. Addiction is the compulsive need and use of a substance that creates habit. It is accepted as mental illness in the diagnostic nomenclature and gives rise to important health, social and economic problems. In the diagnostic nomenclature, addiction was originally included in personality disorders along with other behaviors considered deviant.
But it is now considered a clinical syndrome. Addiction is determined multifactorially, with substantial genetic influence. The development of addictions is also influenced by environmental factors and by the interaction between the two. In the clinical context, addiction puts problematic substance use on the agenda and helps to focus on the difficulties associated with drug use.
But the concept of addiction is also used to distance the consumer from addicts and, in this way, can be countertherapeutic. The concept of addiction has also had a substantial influence on policies. The near-universal ban on drugs such as opiates, cocaine, cannabis and amphetamine has a lot of support. But, unfortunately, it has not been able to prevent the development of problems related to substance use.
Optimism is fostered by the development of respectful ways of thinking about people with addictions, in particular, by advocates of motivational interviewing. Multiple independent genes also mean multiple pathways, likely leading from genetic disposition to drugs to drug addiction. If you're not comfortable calling addiction a disease, that doesn't mean there's something wrong with you. Addiction is a term that means compulsive physiological need and use of a habit-creating substance (such as heroin or nicotine), characterized by tolerance and well-defined physiological symptoms at the time of withdrawal; it has also been used more widely to refer to the compulsive use of a substance known to physically, psychologically or socially harmful user (Maddux and Desmond, 2000).
The impact of multiple independent genes means that humans are born with a degree of risk, rather than with the absence or presence of disposition for the disorder.
