I’m getting a dry / sore throat when I vape
Try the following:
Take a drink of water.
Reduce the number of puffs you take in quick succession.
Make sure there is enough e-liquid in your tank so you’re not getting a dry hit.
If none of that worked:
You might want to consider switching to a higher VG e-liquid as PG delivers a stronger throat hit and can be responsible for a dry throat feeling. Another point to consider is how long ago you stopped smoking cigarettes. Smoking cessation is a form of withdrawal, and one of the symptoms is a sore throat.
