As there are so many different e liquid brands, ingredients, strengths and qualities on the market, there are several reasons as to why your e liquid may be hurting your chest.
The VG : PG Content Is Not Suitable
The VG : PG percentage of e liquids differ but should be stated on the bottle of liquid. If you are on a ‘mouth-to-lung’ kit with a coil of between 1 ohm and 2.1 ohms, then a VG% of 60% or less is typically better suited to your kit. Some liquids of a higher VG are also suitable, but sometimes the higher the VG, it can cause the liquid not to pull through the coil as freely and can cause a sudden dry hit.
If you have an e cig with a coil of between 0.5 ohms and 1 ohm, then a higher VG may be more suitable up to 70% VG : 30% PG.
Alternatively if you have a sub kit, with a coil of 0.5 ohms or less, you are best suited to higher VG’s, so 60% VG or higher is generally smoother for you to vape.
The Nicotine Strength Is Too High
If your nicotine strength is too high the nicotine can hit on your chest too strongly and cause you to cough or irritate you. To check if this is the case for you, it might be worth trying a lower strength and seeing if it is better for you. If you have a sub kit (with a coil of 0.5 ohms or lower), although some people ‘get used to’ higher nicotine strengths and do use them with these kits, generally we would not recommend a nicotine strength of higher than 6mg due to the harshness with this kind of coil.
The Quality Is Not Great
Although there are new regulations offering reassurance about the quality of your e liquid, some individuals are still illegally selling non-TPD compliant liquids. The quality of these liquids can be questionable as there is not necessarily any controls or testing carried out to ensure they are to a good quality. To be sure that your liquid is manufactured and tested in accordance with the UK’s TPD, the bottle of e liquid should have a nicotine warning label stating that nicotine is a highly addictive substance. It also should have an ECID number on it, which is a unique code given by the MHRA confirming it is TPD compliant.
It Is None of the Above
If it is none of the above, sometimes it can just be that certain brands are not suited to you. If this is the case, you are always welcome to visit Vapour Days on the Middle Floor of The Galleries, Bristol, where you can test many different brands to find one which suits you best.
