My throat hurts when I vape, is this normal?
You might want to rethink the nicotine level of your e-juice. A higher nicotine level can be unpleasant especially if you are not used to it.
Alternatively the Propylene Glycol (PG) ratio of your e-juice might not be the right fit. Propylene Glycol (PG) absorbs moisture from its environment, this includes your mouth and throat when you vape. More concentrated mixes will provide a harsher throat which can result in a dry and/or sore throat.
