An unexpected burning or strong coughing sensation when taking a puff from your e-cigarette is a common problem. Often, it's not due to the device itself, but rather an incorrect setting, a worn-out atomizer head, or the wrong e-liquid.
Direct Answer: Why does my e-cigarette cause a scratchy throat?
A sharp scratchy sensation in the throat is usually caused by a burnt atomizer head (dry hit), a too-high nicotine strength with freebase nicotine, or an incorrect mixing ratio (too much propylene glycol PG). A wattage setting that is too high can also cause the liquid to vaporize too hot.
The 4 most common reasons and solutions
-
Burnt coil (Dry Hit): If the cotton in the atomizer head runs dry or is burnt, the vapor will taste burnt and cause a burning sensation in the throat. Solution: Change the atomizer head and let the new coil soak for 5 minutes before the first use.
-
Too much freebase nicotine: Conventional nicotine produces a strong throat hit at higher strengths (from 6 mg MTL or 3 mg DL). Solution: Switch to gentler nicotine salts (Nic Salts).
-
Too high wattage: If the atomizer is operated with too much power, the liquid overheats. Solution: Gradually reduce the power until the vapor remains comfortably cool.
-
Too high PG ratio: Propylene glycol (PG) is the flavor carrier, but it also intensifies the throat hit. Solution: Switch to an e-liquid with a higher VG content (e.g., 70 VG / 30 PG).
