Substance Use, Abuse, and Addiction: A Psychological Perspective

by: Keerthi Meruva

Introduction

Addiction, abuse, and substance use are complex issues that have a big impact on people’s lives, families, and society as a whole. Psychology has examined these phenomena thoroughly to comprehend their causes, functions, and effects. This article examines psychological theories and interventions, intended to address these issues as well as the terminologies, causes, and effects of substance, misuse, and addiction. Substance use includes using psychoactive substances such as alcohol, nicotine, and other illegal drugs. It can be used regularly for cultural, medical, or recreational purposes for experimental or occasional use. Substance abuse and addiction are not always the result of using drugs, but they can be a possibility. When chemicals are used harmfully to change moods and alter reality, it is referred to as substance abuse. Significant impairment or distress, such as health issues, disabilities, and the inability to fulfill important responsibilities. Substance use is marked by its harmful effects or repeated use. Substance dependence, another name for addiction, is a chronic, relapsing condition marked by persistent brain alterations, obsessive drug seeking, and continued use despite negative effects. It often comes with tolerance, which is the need for more of the drug to have the same effect, and withdrawal symptoms when the drug is stopped. Learning the effects of drugs and their consequences on the brain is important.

Causes of Substance Use, Abuse, and Addiction

The development of substance use, abuse, and addiction is influenced by a combination of genetic, environmental, and psychological factors.

Biological Factors:

  • Genetics - Studies show that 40-60% of an individual’s vulnerability to addiction can be attributed to hereditary factors. Genetic variables can impact brain chemistry and the body’s substance metabolism, which can increase or decrease the likelihood of developing substance use disorders.
  • Brain Chemistry - Addiction and substance abuse modify the brain’s reward system. Drugs of abuse usually cause an increase in dopamine release, which is a neurotransmitter linked to reward and pleasure. Tolerance and dependency develop as a result of the brain’s limited capacity to create and respond to dopamine over time.

Psychological Factors:

  • Personality Traits - Addiction to substances is more common in people who exhibit tendencies like impulsivity, sensation seeking, and high levels of stress or anxiety.
  • Mental health disorders - Substance use as self-medication is more common among people with mental health conditions such as depression, anxiety, and PTSD, which raises the risk of substance use disorders.

Environmental Factors

  • Family Environment - Substances can be more likely if there is no parental surveillance, early early substance exposure, or a family record of substance abuse.
  • Social and Peer Influence - Substance use can start and continue as a result of peer pressure and the need to blend in with a social group. Addiction and abuse rates are also greater in social contexts that support or encourage substance use.

Psychological Theories of Substance Use and Addiction

Behavioral Theories
Through classical conditioning, drug use can be linked to specific stimuli or environments. For instance, someone may have a strong desire for a drink when they walk into a bar because they have previously connected that setting with drinking. It could also be through operant conditioning, where substance use is positively reinforced by the instantaneous benefits of drugs or the alleviation of withdrawal symptoms (negative reinforcement) are common sources of reinforcement for substance use. This reinforces the behavior and increases the likelihood that it will happen again.

Cognitive Theories
According to the Expectancy Theory, people’s expectations regarding the consequences of substances have an impact on their use. They are more prone to use a substance if they think it would improve their mood or social relations. The Cognitive-Behavioral method focuses on the interactions that occur between ideas, emotions, and actions. It implies that persistent use and addiction are facilitated by dysfunctional thought processes, such as believing that substance use is an essential coping mechanism.

Social Learning Theory
The Social Learning Theory highlights how imitation and observation play a part in substance use. People can pick up drug usage habits via watching peers, family, or media portrayals. Substance use can be initiated with sustained when social reinforcement and behavior modeling are combined.

Biopsychosocial Model
The biopsychosocial approach offers a thorough knowledge of substance use and addiction by integrating biological, psychological, and social variables. It acknowledges the emergence of substance use disorders cannot be fully explained by a single component, but rather by the interaction of several components.

Conclusion

The physical repercussions of prolonged technology use are also significant. Sedentary behavior associated with excessive screen time can lead to obesity and other health issues. The World Health Organization (WHO) recommends that children aged 5-17 engage in at least 60 minutes of moderate to vigorous physical activity daily, yet a study from the Kaiser Family Foundation found that the average screen time for 8-18-year-olds is over 7.5 hours per day.

Conclusion

Addiction, substance use, and abuse are complicated disorders that call for a sophisticated understanding of psychology. Through an analysis of the interactions between biological, psychological, and social components, we can create preventative and treatment plans that are more successful. To address the obstacles caused by substance use disorders and assist people on their road to recovery, communities, politicians, and healthcare professionals must continue their research together.
