Stimulants01:29

Stimulants

591
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...

Stress Prevention and Stress Management Techniques IV

102
Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

COPD: Management Using Bronchodilators and Corticosteroids

519
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Chronic Obstructive Pulmonary Disease

1.8K
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Inhaled Medications01:23

Inhaled Medications

510
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...

Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants

1.8K

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...

Area of Science:

  • Public Health
  • Tobacco Control
  • Behavioral Science

Background:

  • Homeless individuals often use alternative tobacco products, including e-cigarettes.
  • Understanding perceptions and use patterns of e-cigarettes is crucial for this population.

Purpose of the Study:

  • To examine attitudes toward e-cigarette use among smokers experiencing homelessness.
  • To determine if e-cigarette use patterns are associated with cigarette quit attempts.

Main Methods:

  • Survey of 470 current cigarette smokers recruited from homeless service sites.
  • Analysis of e-cigarette use (dual use) and its association with past-year cigarette quit attempts.

Main Results:

  • 22.1% of participants were 'dual users' (used both cigarettes and e-cigarettes).
  • Dual users perceived e-cigarettes as safer than traditional cigarettes.
  • E-cigarette use patterns (frequency, duration, nicotine concentration) were not linked to quitting cigarette smoking.

Conclusions:

  • E-cigarette use is prevalent among homeless smokers, with perceptions of reduced harm.
  • Current e-cigarette use patterns among this group do not predict cigarette cessation.
  • Further research into motivations for e-cigarette use, especially as cessation aids, is needed to inform interventions.
