Definition of Substance Abuse

Substance abuse, also known as substance use disorder, refers to the harmful or hazardous use of psychoactive substances, including alcohol and illicit drugs. Individuals who engage in substance abuse often experience negative consequences, such as health problems, impaired judgment, and difficulties fulfilling responsibilities at work, school, or home.

Characteristics of Substance Abuse

One of the primary characteristics of substance abuse is the compulsive use of drugs or alcohol despite the negative consequences. Individuals may find it challenging to control their use of substances, leading to a cycle of addiction.

2. Cravings

Intense cravings for drugs or alcohol are common among individuals struggling with substance abuse. These cravings can be overwhelming and make it difficult for individuals to focus on anything else.

3. Tolerance

Over time, individuals may develop a tolerance to the effects of drugs or alcohol, requiring larger amounts to achieve the desired effects. Tolerance can lead to increased substance use and escalate the risk of overdose.

Substance abuse takes a toll on physical and mental health. Chronic substance use can lead to a range of health problems, including liver damage, heart disease, respiratory issues, and mental health disorders such as depression and anxiety.

8. Risky Behaviors

Under the influence of drugs or alcohol, individuals may engage in risky behaviors such as reckless driving, unprotected sex, or criminal activities. These behaviors can have serious consequences and put individuals and others at risk.

9. Legal Issues

Substance abuse can lead to legal problems such as DUI charges, drug possession offenses, or involvement in criminal activities to fund drug habits. Legal issues can have long-lasting repercussions on individuals’ lives.
