Drug Dependence

Drug Dependence

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Drug Abuse and Addiction: Pharmacological Phenomena

Drug Abuse and Addiction: Pharmacological Phenomena

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 necessarily...

CNS Depressants: Alcohol and Nicotine

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

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,...

Cognitive Development During Adolescence

Cognitive Development During Adolescence

During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the recognition that people have...

Conduct Disorder

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Summary

Psychosocial problems were more strongly linked to adolescent drinking in Norway during a period of lower substance use prevalence. However, the association between psychosocial issues and adolescent cannabis use remained stable across high and low prevalence periods.

Area of Science:

Adolescent substance use research
Psychosocial factors and behavior
Public health trends in Norway

Background:

Adolescent drinking and cannabis use in Norway saw a decline in the 2000s.
Previous research suggests a link between psychosocial problems and substance use.

Purpose of the Study:

To test if psychosocial problems were more strongly associated with adolescent substance use during a low-prevalence period (2012/2013) compared to a high-prevalence period (2002).
To examine the relationship between deviant behaviors, depressive mood, and alcohol/cannabis use in adolescents.

Main Methods:

Utilized data from school surveys of nearly 20,000 Norwegian adolescents (aged 14-17) in 2002 and 2012/2013.
Assessed past-year alcohol intoxication (any and frequent) and cannabis use, alongside deviant behaviors and depressive mood.

Main Results:

Prevalence of any alcohol intoxication decreased from 50% (2002) to 28% (2012/2013), and frequent intoxication from 29% to 10%.
Cannabis use prevalence dropped from 15% to 7%.
Psychosocial problems showed a stronger association with drinking outcomes in the low-prevalence period, while associations with cannabis use remained stable.

Conclusions:

The hypothesis that psychosocial problems correlate more strongly with adolescent drinking during low-prevalence periods was partly supported.
The stable association with cannabis use may indicate consistently low engagement even during higher prevalence periods.
