Who Does Drug Addiction Affect?

What’s drug addiction in terms of prevalence? Drug addiction is a pervasive and complex condition. It affects millions of people all over the world today. According to the WHO, over 35 million people suffer from a drug use disorder.2
Contrary to popular opinion, drug addiction affects people of all ages. Addiction is an all-encompassing phenomenon. It transcends age, gender, socioeconomic status, and geographic boundaries. 
This disease can significantly impact various aspects of an individual’s life. So it’s evident that exploring the ‘what’s drug addiction like?’ is important.

What’s Drug Addiction: Substance Abuse and Mental Health Definition

In the realm of substance use disorder and mental health, drug addiction is defined as a chronic brain disorder. It is marked by the persistent use of psychoactive substances. 
Drug addiction can be caused by illicit substances, such as: 

Legal Substances that Can Lead to Addiction

Drug addiction can also be caused by legal substances, such as:
  • Alcohol
  • Prescription medications
  • Nicotine
The defining feature of addiction is compulsive drug use. This can become overwhelmingly powerful and difficult to control.
To understand the answer to ‘what’s drug addiction?’, it is crucial to recognize its multifaceted nature. It arises from a combination of genetic, environmental, and psychological factors. 

What‘s Drug Addiction: The Role of Genetics

Genetic predisposition plays a significant role in addiction. Some people may have a heightened vulnerability to developing addiction. This is due to inherited traits and variations in their brain chemistry. 

What’s Drug Addiction: Environmental Factors

Environmental factors can increase the risk of drug addiction, including:
These factors can contribute to the initiation and progression of addiction. 

What’s Drug Addiction: Co-occurring Mental Health Disorders

Underlying mental health conditions can increase the risk of addiction. Co-occurring disorders are when an individual has a mental health and substance use disorder simultaneously. 

Examples of these conditions include: 
  • Anxiety
  • Depression
  • Post-traumatic stress disorder (PTSD)

What’s Drug Addiction: DSM-5 Criteria

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is widely used by mental health professionals. It provides specific criteria for diagnosing substance use disorders. 
According to the DSM-5, the diagnosis of drug addiction is based on the presence of certain symptoms. These may include:3

Impaired Control

The individual struggles to limit or cease drug use. This remains despite a genuine desire to do so. There is also a persistent craving for the substance. 

Social Impairment

Drug addiction often leads to significant problems in social functioning. Relationships may suffer, and the person may neglect responsibilities. This jeopardizes their personal and professional life.

Risky Use and Consequences

Drug addiction is accompanied by continued use of substances in hazardous situations. This includes driving under the influence or engaging in risky behaviors. 

The person may experience legal troubles, financial instability, or physical harm due to their drug-seeking behavior.

Pharmacological Criteria

Tolerance and withdrawal symptoms are common in drug addiction. Tolerance refers to needing a higher dose of the substance to achieve the desired effects. 
Withdrawal symptoms are the unpleasant physical and psychological symptoms experienced when drug use is reduced or stopped abruptly.
It is important to understand that addiction is not simply a matter of willpower or moral failing. Rather, it is a complex interplay of different factors. So it requires comprehensive and compassionate treatment approaches.

What’s Drug Addiction vs. Drug Tolerance/Dependence?

What’s drug addiction? To gain a better understanding of substance-related phenomena, it is crucial to explore another side of this topic. This refers to the distinctions between drug addiction and drug tolerance/dependence.
Drug addiction encompasses a compulsive pattern of drug-seeking and drug-taking behaviors. The hallmark of addiction is the persistent craving for drugs and the inability to cease or reduce drug use. This often results in significant impairment in various aspects of life.

What’s Drug Tolerance/Dependence?

On the other hand, drug tolerance and dependence are physiological responses. They usually develop with prolonged use and the body’s acclimation to the drug. This acclimation occurs due to the body adjusting to the presence of the drug. 
This, in turn, leads to a decreased response to the same dosage. Consequently, people may need to consume larger quantities or more potent substances to experience the desired effect they previously achieved with smaller amounts.
While psychological dependence on a drug is possible, physical dependence occurs more often. It is characterized by the body’s reliance on a particular substance to function normally. 

What’s Drug Addiction Withdrawal?

Abruptly reducing or ceasing drug use can trigger withdrawal symptoms. These symptoms can vary depending on the substance. However, they commonly include the following:
  • Physical discomfort
  • Cravings
  • Irritability
  • Insomnia
  • Potentially life-threatening symptoms, such as seizures and psychosis

How Does Drug Tolerance/Dependence Affect Addiction?

While drug tolerance and dependence are distinct from addiction, they are closely related. The development of tolerance and dependence can contribute to the progression of addiction. 
As people develop tolerance, they may increase their drug consumption. This heightens the risk of experiencing the reinforcing effects of the substance. 
Dependence and tolerance perpetuate a vicious cycle where higher doses lead to increased tolerance and a further escalation of drug use.

Drug Tolerance/Dependence and Psychological Effects of Addiction

Drug tolerance and dependence can intensify the psychological aspects of addiction. The fear of withdrawal symptoms can drive individuals to continue drug use. This can happen even in the absence of a compulsive desire for the substance. 
Additionally, the psychological effects of dependence, such as the reliance on drugs, can reinforce addictive behaviors and hinder attempts to quit.
Not everyone who develops drug tolerance and dependence will progress to addiction. However, the presence of tolerance and dependence increases the vulnerability to addiction. This is particularly true when combined with genetic, environmental, and psychological factors.

What’s Drug Addiction: Common Signs and Symptoms

Drug addiction can cause a variety of signs and symptoms. Some of these include the following:

Compulsive Drug Use

One of the primary signs of drug addiction is the compulsive need to seek and use drugs. People may find themselves obsessively thinking about obtaining and using drugs. 

They also often prioritize drug-seeking behaviors over other important aspects of life.

Loss of Control

A hallmark of addiction is the loss of control over drug use. People may find it challenging to regulate the amount and frequency of drug consumption. This leads to escalating drug use patterns that exceed their initial intentions. 
Despite negative consequences, like financial struggles, the person continues to engage in drug use. 


Intense cravings for the substance are a common symptom of drug addiction. These cravings can be overpowering, causing a persistent desire to use drugs. 
They also cause difficulty in resisting the urge. Cravings may be triggered by environmental cues, stress, or emotional factors. They can also be a significant driver for relapse.

Physical Changes

Drug addiction can manifest in various physical and psychological changes. Physical signs may include the following:
  • Bloodshot eyes
  • Dilated or constricted pupils
  • Sudden weight loss or gain
  • Changes in sleep patterns
  • Poor hygiene or deteriorating physical appearance

They may also experience noticeable adverse changes in motivation, memory, and cognition.4

Social Withdrawal

Drug addiction often causes individuals to withdraw from social activities and isolate themselves from loved ones. 
They may lose interest in hobbies or previously enjoyed activities. This is because they prefer spending time alone or in drug-related environments.

Financial Difficulties

Drug addiction can place a significant financial burden on individuals. Increased drug use leads to escalating expenses. 
Individuals prioritize obtaining drugs over financial obligations. They may borrow money or engage in illegal activities to sustain their addiction.

Physical and Psychological Symptoms

With prolonged drug use, individuals may develop physical and psychological symptoms. Some of these symptoms can include:
  • Nausea
  • Tremors
  • Sweating
  • Insomnia
  • Anxiety
  • Seizures

Decline in Health and Well-being

Drug addiction can significantly impact an individual’s overall health and well-being. It may lead to deteriorating physical health and a weakened immune system. 
This disorder may also cause chronic illnesses or an increased risk of infectious diseases. Mental health may also suffer, with higher rates of mental disorders manifesting among those with addiction.
By familiarizing yourself with these signs and symptoms of drug addiction, you can better identify when help is needed. Early recognition and intervention offer a higher chance of successful treatment and recovery.

Support groups also offer a sense of community with others who have experienced similar challenges. Sharing personal experiences, insights, and strategies for maintaining sobriety can enhance long-term recovery.

Holistic Approaches

Holistic approaches encompass a range of complementary therapies that focus on the whole person. The goal of a holistic approach is to address physical, psychological, emotional, and spiritual wellness. These therapies support overall well-being and enhance the recovery process.
