Similarities and differences between screen addiction and drug addiction
Pleasurable behaviors, both in the realm of screens and drugs, can be placed on a continuum. On the one hand, we find use that does not generate negative consequences with a significant impact, and, on the other, problematic use , which can be divided into:
- Abuse: when it causes negative consequences without generating dependence.
- Addiction: involves tolerance and withdrawal syndrome.
It is essential to avoid pathologizing all young people and focus on prevention to prevent situations of use or abuse from leading to addictions.
The use of digital environments: concerns and challenges
Behavioral addictions, such as problematic screen use, share several features with substance addictions. Authors such as Javier Carbonell and Enrique Echeburúa have studied these phenomena and shed light on points of agreement and divergence.
Main similarities
Activation of brain circuits
Both drug and screen use activate the brain's reward system , specifically the dopamine circuit. This mechanism reinforces behaviors associated with pleasure, which can lead to dependence. This generates compulsive behaviors that, if restricted, can lead to withdrawal symptoms such as irritability or anxiety. Thus, the constant need for digital stimuli creates patterns of dependence similar to those observed in other addictive disorders.
Positive and negative reinforcement
Initially, both behaviors are maintained by positive reinforcement (pleasure). Later, negative reinforcement— avoiding unpleasant emotions such as boredom or loneliness—sustains the habit.
Withdrawal syndrome
Several studies show that both substance withdrawal and excessive screen use can cause symptoms such as irritability, anxiety or difficulty concentrating .
Adolescent vulnerability
The immaturity of the adolescent brain makes them more susceptible to establishing processes of dependence on substances or screens. This stage is characterized by a lower capacity for self-control and a greater search for new sensations. This, added to social pressure and peer approval, increases the risk of developing dependencies .
Shared risk factors
The risk factors for screen addiction are similar to those for drugs:
- Difficulties in self-management and self-control.
- Affective instability and traits such as low self-esteem or shyness.
- Insufficient parental control and family problems.
- Emotional and social loneliness.
Warning signs of video game addiction
Young people with these difficulties often find the internet a means to satisfy social needs and explore identity, but this can lead to problematic use.
The capacity for self-control is built progressively and requires a supportive environment. Families, schools and communities play a key role in promoting critical thinking, establishing norms and role models , promoting prosocial values and ensuring an equitable and supportive environment that contributes to the healthy development of the young person.
Main differences
Substance versus behavior
Screens do not involve a physical substance and have greater social acceptance . This requires a preventive and educational approach, rather than one focused on abstinence.
Treatment
Problematic screen use does not always require total abstinence as a therapeutic goal; rather, functional and balanced use is sought. Furthermore, digital addiction is often trivialized socially, which makes early detection and treatment difficult .
Direct physical impact
Drugs have obvious harmful physiological effects, while behavioral addictions, although they can cause indirect physical disorders (such as sleep disturbances), do not involve direct organic damage .
Clinical recognition
Although drug addiction is well established in diagnostic manuals such as the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), only gambling disorder and video game addiction have similar formal recognition. Internet or social media addictions still require more research to establish themselves as independent diagnoses.
Ultimately, understanding these similarities and differences is essential for preventive and educational intervention that takes into account the environment and specific needs of adolescents.
