Background:
Evidence concerning the impact of vaping on respiratory infections remains contradictory. Cell and animal studies suggested that vaping may increase vulnerability to respiratory infections, but human data do not confirm this concern.
Case Presentation:
We present a case of a never-smoker who became a vaper and after a few months of e-cigarette use experienced a complete resolution of chronic tonsillitis and a marked improvement in tonsilloliths.
Conclusions:
As this is a never-smoker, the improvements cannot be attributed to smoking cessation. One possible explanation is that the improvement was due to antimicrobial properties of propylene glycol. The hypothesis could be tested by a trial of zero-nicotine e-cigarettes in patients with recurrent bacterial throat infection.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
