According to National Institute of Drug Addiction – addiction is a chronic disease which can be characterized as a drug seeking behavior and use. It is either difficult to control or compulsive despite of it’s harmful and serious consequences.
What is challenging about addiction is it’s interference with an individual’s ability to resist the intense urges to take drugs. It causes persistent changes in the brain which also makes it a “relapsing” disease.
People in recovery are at an increased risk for going back to drug use even after years of not taking drugs.
The long term usage of drugs causes changes in the brain chemical systems and circuits, which includes: learning, judgement, decision-making, memory, behavior and more.
While there are some people don’t get addicted and some do is due to multiple factors. Higher the risk factors, higher will be their chances of getting addicted.
Biology – genes have a role in making a person more prone to addiction. Gender, ethnicity and existing mental disorders may influence the risk of addiction.
Environment – different influences, family and friends, economic status. Other factors such as peer pressure, abuse, early history of drug may increase likelihood of addiction.
Development – interaction between genetic and environmental factors affects addiction risk.
Drugs at any use can lead to addiction. However, it can be cured and prevented.
