Have you been using the same freebase e-liquid but suddenly noticed a stronger or harsher throat hit? In my experience, the nicotine strength is not always the reason. Several other factors can change how a freebase e-liquid feels.

One of the first things to check is your coil. An old or partially burnt coil can make e-liquid taste rough, dry or unpleasant. If the flavour has also become weaker or slightly burnt, replacing the coil is often the first thing worth checking.

The PG/VG ratio can also affect throat feel. PG generally provides more flavour and throat sensation, while VG is smoother and produces denser vapour. If you have changed to an e-liquid with a higher PG content, it may feel noticeably sharper even if the nicotine strength has stayed the same.

 a difference too. In my experience, menthol, ice, citrus and some strong fruit flavours can feel sharper than creamy, sweet or dessert flavours. This can make the e-liquid seem stronger even when the nicotine level has not changed.

Your device settings are another factor. Increasing the power can produce more vapour and change how quickly the e-liquid is heated. If your coil is not designed for the power level you are using, the vape can become hotter and harsher.

Airflow can have an effect as well. A more restricted airflow can create a warmer, more concentrated vape, while opening the airflow can make the experience feel cooler and less intense.

It is also worth checking how the e-liquid has been stored. Excessive heat or prolonged exposure to air can affect an e-liquid's flavour and overall vaping experience.

So, if your freebase e-liquid suddenly feels harsher, don't immediately assume the nicotine strength has changed. Check your coil, PG/VG ratio, flavour, power, airflow and e-liquid storage first.

If the harshness continues, stop using the liquid and check the product information and your device manufacturer's recommendations.
