What's happening in your body

Vape liquid is mostly propylene glycol and glycerine. Both attract water, which is what makes them useful in the liquid and also what they do to the lining of your mouth and throat. In trials of e-cigarettes the most commonly reported side effects are throat and mouth irritation, dry mouth and cough. In one Swiss trial a third of exclusive vapers reported dry mouth after the first week. None of that aerosol is arriving now.

What to expect

Nobody has timed how quickly the mouth and throat settle after stopping, so this is a day for observing. Some people also discover that they drink less water than before, because the sip used to follow the puff. Whatever the cause, a sore throat or a cough that lasts more than three weeks, or any blood, is worth showing to a doctor.

Try this

Notice your throat first thing tomorrow morning and write one word about it in the diary line.

What else you could do

Do it again in two weeks. You are running the study that has not been done. Keep the water habit that went with the vape and drop the vape. Sugar-free gum or lozenges help a dry mouth while it settles.
