Understanding Drug Addiction

Learn about drug addiction

Substance abuse refers to the excessive consumption of alcohol or other drugs, which often leads to the onset of functional disturbances. Those who become trapped within a pattern of ongoing drug or alcohol abuse start to suffer significant difficulty following through with daily responsibilities, which leads to immense distress for not just them, but also for those around them.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders lists the criteria below as being indicative of the presence of a substance use disorder:

  • The substance continues to be used despite the onset or exacerbation of persistent or recurrent physical and/or psychological problems
  • Tolerance develops
  • Withdrawal manifests
  • Use of the substance continues despite the development of persistent interpersonal or social problems that are either directly caused or exacerbated by the effects of that use
  • Important occupational, social, or recreational activities are given up or significantly reduced as a direct result of the substance use
  • Cravings or a strong desire to use the substance are experienced
  • Recurrent use of the substance has resulted in a failure to fulfill major obligations
  • The substance is used in situations where it is physically hazardous
  • The substance is taken in larger amounts or over a longer period of time than was originally intended
  • There is an ongoing desire to reduce, eliminate, or control the use of the substance, but attempts at doing so have been unsuccessful
  • A significant amount of time is spent in activities that are necessary in order to obtain, use, or recover from the use of the substance

Depending on the specific substance that is being abused, different criteria will be met. However, the presence of any of the aforementioned criteria will undoubtedly lead to serious impairment and distress in an individual’s life. As a result, it is critical that treatment be obtained when an individual is grappling with the abuse of or addiction to any type of substance.

Statistics

Drug addiction statistics

The National Institute on Drug Abuse (NIDA) reports that between 80% and 90% of adults over the age of 18 have abused one or more substances at some point in their lives. Alcohol, marijuana, and prescription medications are believed to be the most commonly abused. In addition, the Substance Abuse and Mental Health Services Administration (SAMHSA) notes that more than 20 million people are struggling with substance use disorder, yet less than 15% of these individuals will get treatment to defeat their addictions.

Causes and Risk Factors

Causes and risk factors for drug addiction

The causes and risk factors that might make a person more vulnerable to suffer from substance use disorder are explained below:

Genetic: Substance use and addiction have long been known to possess genetic links. In fact, research has suggested that nearly 60% of one’s likelihood of struggling with substance use disorder can be found within his or her genetic makeup. In other words, those who have family members who battle substance abuse and addiction are more likely to suffer from the same problems than they would be if they did not have his genetic background.

Environmental: Numerous environmental factors can play a role in an individual’s vulnerability to starting to experience with alcohol or drugs, and subsequently developing an addiction. Coming from a low socioeconomic background, being exposed to violence and crime, and having peers who partake in substance abuse can all increase one’s likelihood that someone will start using drugs and/or alcohol. In addition, being subjected to neglect or abuse, suffering another form of trauma, or suffering from symptoms of a mental health problem can lead an individual towards the use of substances.

Risk Factors:

  • Experiencing a trauma
  • Poverty
  • Witnessing violence
  • Family history of addiction
  • Personal or family history of mental illness
  • Possessing a novelty-seeking temperament
  • Suffering from physical, emotional, or sexual abuse and/or neglect
  • Possessing an impulsive personality
