Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants


Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
Drug Dependence01:17

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...
Stimulants01:29

Stimulants

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...
Drug Abuse and Addiction: Pharmacological Phenomena01:15

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 Nicotine01:27

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...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

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.

Summary
This summary is machine-generated.

Impulsivity traits in smokers are linked to different types of craving. Sensation seeking increases appetitive craving, while urgency and lack of perseverance increase negative affect craving when exposed to smoking cues.

Area of Science:

  • Behavioral Psychology
  • Addiction Science
  • Neuroscience

Background:

  • Cigarette smoking is associated with personality traits, notably impulsivity.
  • Higher impulsivity in smokers correlates with greater difficulty in quitting.
  • The mechanisms linking impulsivity and smoking cessation challenges, particularly cue-induced craving, require further investigation.

Purpose of the Study:

  • To examine the association between specific facets of impulsivity and cue-induced craving in regular smokers.
  • To differentiate how distinct impulsivity traits (sensation seeking, lack of premeditation, lack of perseverance, urgency) relate to craving responses.

Main Methods:

  • Sixty regular smokers participated in a repeated measure, counter-balanced design.
  • Participants were exposed to both a smoking cue and a neutral cue.
  • Mixed effects regression models were used to analyze the data.

Main Results:

  • Smokers high in sensation seeking reported increased appetitive craving following smoking cue exposure.
  • Smokers high in urgency and lack of perseverance reported increased negative affect craving after smoking cue exposure.
  • These findings highlight differential effects of impulsivity facets on craving.

Conclusions:

  • The relationship between impulsivity and cue-induced craving is multifaceted.
  • Considering impulsivity as a single construct may obscure important nuances in craving responses.
  • These results have implications for understanding smoking behavior and developing targeted interventions.
