Summary
Simultaneous alcohol and cannabis use (SAM) is common in young adults. High sensation seeking and urgency facets of impulsivity are linked to increased SAM use, indicating a vulnerability for hazardous behaviors.
Area of Science:
- Psychology
- Addiction Science
- Neuroscience
Background:
- Simultaneous use of alcohol and cannabis (SAM) is prevalent among young adults.
- Impulsivity is a known risk factor for substance use, but its specific facets in relation to SAM use are understudied.
Purpose of the Study:
- To compare latent profiles of impulsivity facets in young adults.
- To examine the association between these impulsivity profiles and recent SAM use versus alcohol-only use.
Main Methods:
- Latent profile analysis of five impulsivity facets (negative urgency, lack of perseverance, lack of premeditation, sensation seeking, positive urgency).
- Survey data from 542 young adults on past-year substance use and typical impulsivity.
- Regression analyses to identify predictors of SAM use.
Main Results:
- Four impulsivity profiles were identified: low impulsivity, high sensation seeking/urgency impulsivity, moderate impulsivity, and high lack of premeditation/perseverance impulsivity.
- The 'high sensation seeking/urgency impulsivity' profile was significantly associated with higher rates of SAM use.
- Sensation seeking was the only individual facet to predict SAM use likelihood.
Conclusions:
- Impulsivity, particularly sensation seeking and urgency, is a significant individual difference factor associated with SAM use in young adults.
- Young adults engaging in SAM use may be more vulnerable due to heightened sensation seeking and urgency, increasing risks for hazardous consumption.

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...

01:15Drug Abuse and Addiction: Pharmacological Phenomena
628
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 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.

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.

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...

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
315
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...
