Vaping has become a common practice, raising concerns about its potential effects on the body. Many individuals who vape report throat irritation, which can sometimes manifest as visible red spots. This symptom often leads to questions about the direct link between vaping and these specific throat changes.
How Vaping Can Affect the Throat
Vaping involves inhaling an aerosol, often called vapor, produced by heating an e-liquid. This e-liquid typically contains components that can irritate the sensitive tissues of the throat.
Propylene glycol (PG) and vegetable glycerin (VG) are the primary base ingredients in most e-liquids. PG, a synthetic chemical, attracts and absorbs moisture, which can lead to dryness in the mouth and throat, potentially causing irritation and a scratchy sensation. Some individuals may also have a sensitivity or allergy to PG, which can result in a sore throat, coughing, and in some cases, redness or itching around the mouth.
Vegetable glycerin (VG), derived from plant oils, also contributes to throat dryness and irritation, though generally less than PG. While VG is often preferred for larger vapor clouds and a smoother inhale, prolonged exposure to its aerosol can irritate the airways, potentially leading to a chronic cough or bronchitis-like symptoms over time. Flavorings added to e-liquids can also play a role in throat irritation. Certain flavors, particularly acidic ones like citrus or sour, or strong flavors such as menthol, cinnamon, or peppermint, might contain chemical profiles that increase irritation.
Beyond ingredients and flavorings, the heating process can contribute to discomfort. High wattage settings can lead to “dry hits,” where the coil burns the wick due to insufficient e-liquid, producing a harsh sensation and potentially causing a sore throat. Heavy metals leaching from the heating element, volatile organic compounds, and diacetyl have also been identified as potential throat irritants.
Other Potential Causes of Throat Redness
While vaping can contribute to throat irritation and red spots, many other common conditions can cause similar symptoms. Infections, both viral and bacterial, are frequent culprits. Viral infections like the common cold, flu, or specific viruses (e.g., enteroviruses, coxsackieviruses) often lead to a sore throat and sometimes small red spots or blister-like ulcers.
Bacterial infections, such as strep throat, are also a common cause of throat redness and can present with tiny red spots on the soft or hard palate. Fever, swollen tonsils, and difficulty swallowing often accompany these infections. Allergies to environmental factors or foods can trigger post-nasal drip, leading to throat irritation and inflammation. Acid reflux, where stomach acid flows back into the esophagus, can cause a burning sensation and chronic throat irritation, sometimes resulting in redness. Excessive coughing, from a respiratory infection or asthma, can physically irritate the throat lining, leading to generalized redness or small burst blood vessels appearing as red spots.
When to Consult a Healthcare Professional
If you notice persistent red spots on your throat, consult a healthcare professional for an accurate diagnosis. While some irritation might relate to vaping or minor issues, certain symptoms warrant medical attention regardless of vaping habits. Seek medical advice if red spots are accompanied by high fever, difficulty swallowing or breathing, or significant pain.
Swollen lymph nodes, white patches or streaks on tonsils, or a rash elsewhere on the body with throat redness also indicate a medical evaluation is needed.
If throat symptoms do not improve within a few days, or worsen despite home remedies like hydration and rest, a doctor can determine the cause and recommend treatment. Early diagnosis is important, especially for bacterial infections requiring antibiotics to prevent complications.
