Can Vaping Cause Sensitivity in the Throat?
Health Guides
Throat sensitivity is one of the most common reasons vapers come into our Coventry store looking for help. Here is a thorough guide to what causes it, what makes it worse and how to resolve it.

The overview
Vaping and Throat Sensitivity
Usually PG, but several other causes contribute
The cause is almost always identifiable and the fix is usually a liquid change
Throat sensitivity from vaping, soreness, irritation, a raw or scratchy feeling, persistent throat clearing, is experienced by a significant proportion of vapers at some point and is the primary complaint that drives customers into our store seeking help. The cause is identifiable in the vast majority of cases. Propylene glycol is the most common culprit: its drying and mildly irritant properties affect the throat mucosa with every inhalation. Nicotine strength, flavouring compounds, dehydration, coil condition and inhalation technique all contribute in varying degrees depending on the individual.
Cause by cause
What Is Causing Your Throat Sensitivity
Propylene Glycol: the Most Common Cause
High-PG liquids (50% PG and above) produce a pronounced throat hit that can irritate the pharyngeal and laryngeal mucosa over time in sensitive individuals. PG is a solvent that dries the mucous membrane lining and creates a mildly abrasive contact effect. Vapers using standard 50/50 liquids who experience persistent throat soreness will almost always see significant improvement by switching to a 70/30 VG-dominant or higher-VG formulation. The reduction in throat hit and mucosal irritation from this simple change is often dramatic.
High Nicotine Concentration Amplifying Throat Hit
Higher nicotine concentrations increase the harshness of inhalation, particularly with freebase nicotine formulations. At 12mg and 20mg freebase, the throat hit can be severe enough to cause persistent soreness with regular use. Nicotine salts reduce this substantially, they deliver nicotine at higher concentrations with a smoother throat profile, but even nicotine salts at 20mg can cause throat sensitivity in people with particularly reactive mucosae. Reducing nicotine strength alongside switching to a higher-VG formulation addresses both contributing factors simultaneously.
Dehydration Making the Throat More Vulnerable
A chronically dry throat is more sensitive to any inhaled substance. PG-induced dehydration removes the mucus layer that normally protects the throat epithelium, leaving the tissue more directly exposed to vapour compounds and more prone to irritation. Many vapers find their throat sensitivity improves significantly, sometimes entirely, with consistent increased water intake alongside their existing liquid setup, without needing to change product at all.
Specific Flavouring Compounds
Some flavouring compounds are known throat irritants for sensitive individuals. Menthol and cooling agents can produce a burning sensation in reactive throats. Cinnamon, citrus concentrates and some other flavour profiles also trigger throat irritation in a minority of vapers. If your sensitivity is worse with certain flavours and better with others, a flavouring compound sensitivity is the cause. Switching to a neutral, fruit or simple flavour profile for a test period will confirm this.
A Degraded or Unprimed Coil
A coil at the end of its life delivers harsher vapour that is significantly more irritating to the throat than fresh vapour. The burnt compounds produced by an overheated or degraded coil cause immediate throat irritation and rawness. If your sensitivity appeared suddenly rather than gradually, or if the vapour tastes burnt or harsh, coil replacement is the first thing to check.
01
Switch to 70% VG or higher
This addresses the primary cause in the majority of throat sensitivity cases. Most pod devices and all sub-ohm devices work well with 70/30 VG-dominant liquids.
02
Reduce nicotine strength or switch to nicotine salts
If you are using high-strength freebase nicotine, switching to nicotine salts at the same concentration or stepping down to a lower strength reduces throat harshness significantly.
03
Drink substantially more water
Maintaining airway hydration reduces vulnerability to PG irritation and flavouring compounds.
04
Replace your coil
If sensitivity appeared suddenly, check the coil. Replace, prime thoroughly, saturate and wait before use.
