The majority of medications work by overstimulating the reward circuit in the brain with the chemical messenger dopamine. Dopamine reward circuit surges encourage enjoyable but harmful behaviours, encouraging people to engage in the action again.

Your brain will eventually get used to the extra dopamine. You might need to use more dopamine to feel the same pleasure. Other things that you love, like eating and spending time with your family, might offer less pleasure.

The addiction to prescriptions or illegally obtained narcotics pain medications, known as opioids, is also possible. The United States is experiencing an epidemic of this problem. In 2018, opioids were involved in nearly two-thirds the deaths due to drug overdoses.

For example, long-term opioid use for pain relief can lead to tolerance or even physical dependence. However, this does not mean that you are addicted. Addiction is rare when drugs are given under medical supervision.

The brain's chemical systems and circuits are also affected by long-term use. These changes can impact learning, judgement and decision-making as well as memory and behavior. People who use drugs often continue using them even though they are aware of the dangers.

Biology. A person's genetic makeup can influence around half of their likelihood of developing addiction. Other variables that can influence your risk of addiction include gender, ethnicity, or the presence of other mental diseases.

Other chemical systems and brain circuits are also altered over time, which can result in cognitive and behavioral changes such as learning and memory, judgement, decision-making and stress. Many drug users continue to use drugs even though they recognize the dangers of addiction.

When an individual continues to use drugs, their brain adapts by diminishing the capacity of reward circuit cells to respond to it. This will continue to occur as long as the individual continues to consume drugs. This process, known as tolerance, has the effect of diminishing the individual's high compared to the high they had when they first took the drug. They might attempt to achieve the same high by ingesting more of the chemical. Due to these brain alterations, the individual is typically unable to get pleasure from activities they once enjoyed, such as eating, sexual activity, or social interaction.
