Drug Abuse and Addiction: Pharmacological Phenomena

584
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Substance Use Disorders Affecting Sleep

204
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Diagnostic and Statistical Manual of Mental Disorders (DSM)

110
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Attention-Deficit/Hyperactivity Disorder

135
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

299
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Stimulants01:29

Stimulants

265
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Summary

Methamphetamine use disorder (MAUD) and gambling disorder (GD) often co-occur, with nearly half of men in treatment for MAUD also having GD. Key risk factors for co-occurring GD include MAUD symptom severity and family gambling history.

Area of Science:

  • Addiction Psychiatry
  • Clinical Psychology
  • Public Health

Background:

  • Methamphetamine use disorder (MAUD) and gambling disorder (GD) frequently co-occur, complicating treatment outcomes.
  • Individuals with co-occurring MAUD and GD often present with more severe clinical profiles.

Purpose of the Study:

  • To investigate the prevalence and clinical characteristics of co-occurring gambling disorder (GD) in men undergoing compulsory treatment for methamphetamine use disorder (MAUD).
  • To identify potential risk factors associated with the co-occurrence of MAUD and GD.

Main Methods:

  • A cross-sectional study involving 350 men with MAUD at a compulsory drug rehabilitation center in China.
  • Semi-structured interviews, the Barratt Impulsiveness Scale-11, and data on childhood upbringing and drug use characteristics were employed.
  • Statistical analyses included independent sample t-tests and dichotomous logistic regression to predict co-occurring GD.

Main Results:

  • The prevalence of gambling disorder (GD) among men with methamphetamine use disorder (MAUD) was 45.1%.
  • Post-onset methamphetamine use with co-occurring gambling disorder (PoMAU-GD) was observed in 39.1% of participants.
  • Predictors of PoMAU-GD included the number of MAUD symptoms, family history of gambling, age of first sexual activity, and non-planning impulsivity, explaining 24.0% of the variance.

Conclusions:

  • The high prevalence of GD in individuals with MAUD underscores the need for integrated screening and treatment approaches.
  • Identifying specific risk factors can aid in targeted interventions for individuals with co-occurring MAUD and GD.
  • Clinical settings treating MAUD should routinely assess for gambling disorder to improve patient outcomes.
