What is addiction?
Addiction is a complex condition – a neurological disease that manifests through compulsive engagement in certain behaviors despite negative consequences. It can involve substance addictions such as alcohol and drugs, or behavioral addictions like gambling, shopping, or internet use. Addiction affects the reward system of the brain by altering its structure and function, resulting in a strong craving for the addictive substance or behavior.
Physical and psychological dependency
Physical dependence means that the body has adapted to the presence of a substance. If the intake of the substance is suddenly reduced or stopped, the individual may experience withdrawal symptoms. Examples of such symptoms include shaking, sweating, nausea, and anxiety. Physical dependence is especially common with the use of alcohol, opioids, and certain medications.
Psychological dependence, on the other hand, is a condition where a person experiences a strong mental desire or craving for a particular substance or activity. This form of dependence is often more subtle and harder to define, but it can be just as powerful as physical dependence. For example, individuals who are psychologically dependent on gambling may feel an overwhelming need to gamble in order to achieve a sense of euphoria or to avoid negative emotions such as anxiety or depression.
Dependency mechanisms in the brain
Addiction affects the brain’s reward system, which primarily involves the neurotransmitter dopamine. When a person engages in an addictive activity or consumes a substance, the reward system is hijacked and large amounts of dopamine are released in the brain. This creates a strong feeling of pleasure or euphoria. Over time, the brain adapts by producing less dopamine naturally or by reducing the number of dopamine receptors. This leads the individual to require more of the substance or behavior to achieve the same pleasurable effect—a process known as tolerance.
Misuse and Addiction
Misuse does not necessarily mean dependence, but it can lead to it. The difference between misuse and addiction is that misuse refers more to the harmful or problematic patterns of use, while addiction involves changes in brain structure and function.

Different types of addiction
Alcohol
Alcohol is one of the most used and misused substances in the world. It works as a depressive sedative which affects the central nerve system and leads to the consumer feeling relaxed, decreased inhibitions and a sensation of euphoria. Overconsumption of alcohol can lead to both physical and psychological dependency and serious health issues, since alcohol is very damaging to your health.
Drugs
Substance abuse is a serious and complex issue that affects individuals and communities on many levels. The causes of addiction are often multifaceted, involving both genetic and environmental factors. The consequences are far-reaching, impacting both physical and mental health as well as social relationships.
Pharmaceuticals
Misuse of different pharmaceutical substances can arise when prescription pills, such as opioids, benzodiazepines and other stimulants, is used in a different way than prescribed by your doctor. These different pharmaceuticals can have a powerful effect on the reward system of the brain and can lead to dependency and addiction.
Gambling
Gambling addiction is a psychologically, behaviorally dependency which manifests a compulsive gambling, despite obvious negative consequences for the individual’s economy, relationships and psychological wellbeing. It is ubiquitously acknowledged as a psychological disorder and may very well cause as much damage as any substance addiction.
