Drugs Abuse

Drug abuse occurs when a person takes drugs excessively to reduce stress or physical symptoms and arouse pleasure. In some cases, the user may be involved in binge-like cycles that may be an indication of addiction.

Repeated drug abuse alters some parts of the brain such as the reward centre, giving rise to addiction. When a person reaches the point of addiction, they are unable to quit drugs or alcohol even after experiencing negative impacts like physical health problems, relationship issues, legal problems and job under-performance.

What Is Drug Abuse?

Drug abuse is the detrimental and dangerous use of legal or illegal substances. Such substances may lead to dependence syndrome, which is a collection of cognitive, physiological and behavioural phenomena. The syndrome develops after persistent drug intake and is characterized by reduced self-control, increased tolerance, consumption despite dangerous effects and painful withdrawal symptoms when the user tries to quit.

Drug abuse occurs when a person uses drugs in a way that is not medically recommended, such as taking more than the amount prescribed. In many cases, the user consumes the drug for purposes of creating pleasurable effects and feelings of ecstasy in the brain.

  • Skin changes
  • Dental issues
  • Bloodshot or glazed eyes
  • Changes in hygiene

Drug Abuse and Addiction

The terms drug abuse and addiction are commonly used interchangeably. However, they are two different concepts.

A person abusing drugs may not become addicted to them. The definition of drug abuse is concerned with how a person uses drugs improperly and excessively. The effects of their actions may not have a remarkable impact on their life.
Drug abuse is associated with damaging behaviour. However, the user may still retain some degree of control over their drug intake.

Addiction comprises detrimental physical and psychological effects that the drug causes in the user. When a person becomes addicted, it will seem nearly impossible to quit consuming the substances. Addiction is a disease and occurs as a result of chemical imbalances in the brain that lead to physical and even psychological dependence.
