The Psychology of Drug Addiction

Addiction is a problem that affects not only the person who is addicted to drugs, but their family and society as a whole. This is why it’s important for us to understand the psychology of drug addiction.

In this article, I’ll explain how psychological theories can help us understand addiction and its consequences.

Neurobiological factors

  • Genes. The genes you inherit from your parents can influence the brain’s reward system, which dictates how you experience pleasure. If you have a family history of addiction, you’re more likely to become one yourself.
  • Brain chemistry. Your brain chemistry plays a big role in drug addiction because it can affect how drugs impact the body and mind. The way drugs interact with neurotransmitters is also part of this process—the “neurotransmitter” chemicals send signals between neurons in your brain and other parts of your body (such as muscles or organs). For example, dopamine is one neurotransmitter that affects moods; when there’s not enough dopamine flowing through our systems naturally (as happens if we are depressed), we may seek out ways to raise it artificially instead—namely by taking drugs like cocaine or methamphetamines that artificially raise dopamine levels in our brains as well.* Neurotransmitters such as serotonin are also affected by drug use; for example: – Cocaine causes an increase in serotonin levels which causes feelings of euphoria and energy but also leads many users into addiction later on because they now need large amounts just to feel normal again after withdrawal symptoms occur once the high wears off

Psychological factors

You may have heard that drug addiction is a mental disorder. While this can be true, it’s important to understand that psychological factors are often the cause of drug use rather than a result of it. Psychological factors include stress, depression and anxiety—and they’re all important parts of the human experience.

If you find yourself struggling with mental health issues as well as substance abuse problems, don’t feel bad about seeking help from a professional therapist or doctor! Professional treatment will allow you to address both your psychological needs and any underlying issues that may have led you into using drugs in the first place.

Environmental factors

Environmental factors are important because they can help explain why some people take drugs, while others do not. These include:

  • Social group – Peer pressure is a major factor in drug use. If you hang out with friends who do drugs, it’s more likely that you will too.
  • Family history of addiction – If your parents or other relatives were addicted to drugs, you are more likely to become addicted as well.
  • Stressful life events – Many people who develop drug addictions have had stressful experiences in the past (e.g., the death of someone close to them). These events can lead them to seek relief through drugs and alcohol.

The exact cause of drug addiction is not known, but there are many factors that play a role, including genes and brain chemistry.

The exact cause of drug addiction is not known, but there are many factors that play a role, including genes and brain chemistry. For example, people who have an increased risk of addiction may have an altered brain structure or function that makes them more vulnerable to developing an addiction.


Drug addiction is a complex phenomenon and the exact cause is not known. There are many factors that play a role, including genes and brain chemistry. It is important that we continue to research these factors in order to better understand and treat drug addiction.
