Tobacco Control
|June 15, 2021
Summary
Area of Science:
- Tobacco Control
- Public Health
- Adolescent Health
Background:
- Introduction of 'ice' e-cigarette flavors (fruity/sweet + cooling) in the US market.
- Limited understanding of prevalence and correlates of ice flavor use among young adults.
Purpose of the Study:
- Investigate the prevalence of 'ice' e-cigarette flavor use in young adults.
- Examine associations between ice flavor use and combustible tobacco use, vaping dependence, frequency, and device type.
Main Methods:
- Cross-sectional study of 344 young adult e-cigarette users in Los Angeles (May-August 2020).
- Web-based surveys assessed past 30-day e-cigarette flavor use (menthol/mint, fruit/sweet, ice).
- Outcomes included combustible tobacco use, vaping dependence symptoms, frequency, and device type.
Main Results:
- Nearly half (48.8%) of young adult users preferred 'ice' flavors.
- 'Ice' flavor use associated with increased vaping frequency and dependence compared to menthol/mint and fruit/sweet.
- Ice flavor users more likely to use disposable e-cigarettes and combustible tobacco.
Conclusions:
- 'Ice' e-cigarette flavors are popular among young adults.
- Ice flavor use is linked to higher nicotine vaping frequency, dependence, and combustible tobacco use.
- Further research on ice flavor determinants and health impacts is crucial.

01:29Stimulants
580
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...

504
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...

01:27Upper Respiratory Drugs: Decongestants
492
Decongestants are a class of medications used primarily to alleviate nasal congestion, a common symptom resulting from allergies, colds, sinusitis, and other upper respiratory tract infections. These drugs work by activating α-adrenergic receptors, constricting small blood vessels in the nasal membranes. This action results in the opening of clogged nasal passages, thereby facilitating sinus drainage and relieving congestion.

01:18Vaporization
36.4K
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...

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
608
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

01:27Emerging Adulthood
282
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...
