Which of the following may be inhaled when vaping?

Answer:
When vaping, a variety of substances can be inhaled. Vaping devices heat up a liquid, which typically contains nicotine, flavorings, and other chemicals, to create an aerosol that users inhale into their lungs. Let’s break down the main components that may be inhaled during vaping:

  1. Nicotine:

    • Nicotine is the addictive substance found in tobacco. It is commonly included in e-liquids, the substance vaporized in e-cigarettes. Nicotine levels can vary depending on the e-liquid, but it is typically measurable in milligrams per milliliter.

  2. Propylene Glycol (PG) and Vegetable Glycerin (VG):

    • These are the primary base liquids used in e-liquids. Propylene glycol is a synthetic compound that is used to produce the ‘throat hit’ sensation, while vegetable glycerin is a natural compound that is viscous and produces thick vapor clouds.

  3. Flavorings:

    • E-liquids come in a variety of flavors ranging from fruity to tobacco to dessert flavors. These flavors are created using food-grade flavoring agents. However, some of these flavorings can decompose under heat and form potentially harmful byproducts.

  4. Heavy Metals:

    • Metals such as nickel, lead, and chromium can be present in the aerosol due to the heating elements used in the vaping device. These metals can leach into the e-liquid and become aerosolized during vaping.

  5. Carbonyl Compounds:

    • Heating of the e-liquid can lead to the formation of carbonyl compounds such as formaldehyde, acetaldehyde, and acrolein. These are known irritants and have been classified as carcinogenic or potentially carcinogenic.

  6. Ultrafine Particles:

    • The vapor produced by vaping contains tiny particles that can penetrate deep into the respiratory system. These particles can include various chemicals, and inhaling them can pose health risks.

  7. Volatile Organic Compounds (VOCs):

    • These are gases emitted from certain liquids or solids, including those used in vaping. Some VOCs can have short- and long-term adverse health effects.

Final Answer:
When vaping, one may inhale nicotine, propylene glycol, vegetable glycerin, flavoring agents, heavy metals, carbonyl compounds, ultrafine particles, and volatile organic compounds. The inhalation of these substances can pose various health risks, and it’s important to be aware of what is entering the lungs from vaping devices.
