Stimulants01:29

Stimulants

785
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...

Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants

2.0K

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...

Vaporization01:18

Vaporization

37.1K
The physical form of a substance changes by changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. For vaporization to occur, kinetic energy must be greater than the intermolecular forces that keep molecules bonded. The amount of energy needed to vaporize a quantity of liquid at a given pressure and a constant temperature is called the heat of vaporization. When...

Internal Combustion Engine01:20

Internal Combustion Engine

2.4K
The internal combustion engine is a heat engine that uses the byproducts of combustion as the working fluid instead of using a heat transfer medium to transfer heat. The combustion is done in a way that produces high-pressure combustion products that can be expanded through a turbine or piston to create work. Internal combustion engines can again be categorized into three kinds: (1) spark ignition gasoline engines, most commonly used in automobiles, (2) compression ignition diesel engines that...

Inhaled Medications01:23

Inhaled Medications

652
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Sources of Self-Esteem I: Family Experience

141
Self-esteem, a crucial component of psychological development, is significantly shaped by familial experiences. The early parent-child relationship serves as a foundational influence on a child's self-concept, with long-lasting effects extending into adolescence and adulthood.Parental Behaviors and Early Self-Esteem FormationEmpirical studies have identified four principal parental behaviors that foster healthy self-esteem in children. These include expressions of acceptance, affection, and...

Area of Science:

  • Public Health
  • Adolescent Health
  • Tobacco Control

Background:

  • Youth e-cigarette use has risen as traditional smoking declines.
  • Understanding how adolescents access e-cigarettes is crucial for intervention.
  • Limited research exists on youth e-cigarette acquisition pathways.

Purpose of the Study:

  • To investigate the primary sources of e-cigarette acquisition among adolescents.
  • To identify demographic and social factors associated with how youth obtain e-cigarettes.

Main Methods:

  • Analysis of data from 640 middle and high school students (under 18) from the 2017 North Carolina Youth Tobacco Survey.
  • Utilized chi-square tests and multivariable logistic regressions to examine acquisition correlates.
  • Focused on students who reported e-cigarette use in the past 30 days.

Main Results:

  • Over half of youth (51.5%) acquired e-cigarettes from a friend.
  • Older youth (12th grade) were more likely to obtain them from vape shops or retail outlets.
  • Living with an e-cigarette user increased the likelihood of acquisition from family members.
  • Current smokers had higher odds of obtaining e-cigarettes from retail outlets and lower odds from friends.

Conclusions:

  • Friends are the predominant source for youth e-cigarette acquisition.
  • Family members and retail outlets are also significant sources, influenced by factors like age and household use.
  • Findings can inform targeted strategies to reduce youth access to e-cigarettes.
