In this way, how does one develop an addiction?

Addiction develops when the urge to take a substance hijacks parts of the brain that reward behavior and provides benefits for the body. Substance-related disorders also impact the area of the brain responsible for emotions and decision-making.

Likewise, how addiction occurs in the brain? Addiction impacts the brain on many levels. The chemical compounds in stimulants, nicotine, opioids, alcohol, and sedatives enter the brain and bloodstream upon use. Once a chemical enters the brain, it can cause people to lose control of their impulses or crave a harmful substance.

Then, why do we get addicted?

As individuals continue with addictive habits or substances, the brain adapts. It tries to reestablish a balance between the dopamine surges and normal levels of the substance in the brain, Morikawa said. To do this, neurons begin to produce less dopamine or simply reduce the number of dopamine receptors.

What is the scientific definition of addiction?

Addiction is defined as a chronic, relapsing disorder characterized by compulsive drug seeking, continued use despite harmful consequences, and long-lasting changes in the brain. It is considered both a complex brain disorder and a mental illness.
