Why is it cold when I hit my vape?
Leave a message
The cold sensation when you vape is typically caused by synthetic cooling agents intentionally added to the e-liquid. They work by triggering the same cold-sensitive nerves in your mouth and throat that react to actual low temperatures.
Here's a breakdown of the main chemicals responsible and how they differ:
| Chemical Type | Common Examples | How It Creates the "Cold" Sensation | Where It's Found |
|---|---|---|---|
| Synthetic Cooling Agents | WS-3, WS-23 (often called "koolada") | Activates the TRPM8 nerve receptor directly, creating a pure cooling effect without a strong minty taste. | Very common in "ice" or "frost" flavored disposable vapes like Puff Bar. Often paired with fruit flavors (e.g., "Raspberry Ice"). |
| Natural Cooling Agent | Menthol (from mint) | Also activates the TRPM8 receptor but has a distinctive minty flavor and aroma. | Found in traditional menthol flavors and some "ice" hybrids. |
🔬 How They Work and Safety Considerations
These cooling agents were originally developed for oral use in products like candy and gum. While they are generally recognized as safe for eating, a key point from the scientific review is that the long-term health effects of inhaling them daily are unknown and merit further study.
The industry uses them because the pleasant cooling sensation can mask the harshness of nicotine, potentially making the vape smoother to use.
💡 How to Identify Them
If you want to know if your vape contains these agents:
Check the flavor name: Terms like "Ice," "Frost," "Cool," or "Menthol" are clear indicators.
Look for "Koolada": Some manufacturers or DIY e-liquid sellers list "koolada" as an ingredient, which refers to WS-3 or WS-23.
Review brand information: Reputable brands sometimes list product ingredients or specifications online.
