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.

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...

Longitudinal Research

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Phase II Reactions: Methylation Reactions

Phase II Reactions: Methylation Reactions

Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

Drug Elimination: The Concept of Clearance

Drug Elimination: The Concept of Clearance

Drug elimination refers to removing drugs from the body, either through urine by the kidneys or through bile by the liver. Drug clearance is a pharmacokinetic parameter that measures the efficiency of drug removal from the bloodstream within a specific time frame. It is calculated as the rate at which a drug is eliminated from plasma divided by the plasma concentration of the drug.
Drug clearance is not limited to renal excretion but encompasses all organs involved in drug elimination,...

Summary

Treatment dropout is high for amphetamine-type stimulant users. This study found minimal differences between those who dropped out and those who stayed, except for higher beer consumption in the dropout group.

Background:

Amphetamine-type stimulants (ATS), including methamphetamine, are globally prevalent illicit substances.
Stimulant users exhibit higher treatment dropout rates compared to other substance users.
Factors like younger age, severe substance use disorder, low motivation, and mental health issues predict dropout.

Purpose of the Study:

To investigate differences between individuals who dropped out and those who completed a brief intervention for ATS use.
To identify predictors of treatment retention in stimulant use disorder.

Main Methods:

A comparative analysis was conducted on 21 participants who dropped out and 32 who remained in a brief intervention.
Variables assessed included substance use, methamphetamine dependence severity, alcohol consumption (spirits, wine, beer), motivation, depressive and anxiety symptoms, life satisfaction, and self-efficacy.

Main Results:

No significant differences were found between dropout and completer groups across most assessed variables.
The only statistically significant difference was higher beer consumption in the 30 days prior to intervention among those who dropped out.

Conclusions:

Current findings suggest that common substance use and personal characteristics do not strongly differentiate between dropout and retention in ATS treatment.
Further research is needed to understand the complex factors influencing treatment dropout in this population.
