When you start vaping, typically the first thing anyone will recommend you look at is your nicotine strength. Getting the strength just right is important for a few reasons. First and foremost - it needs to be strong enough to keep away cigarette cravings. However, you don’t want it to be too strong or you might be put off because it’s too harsh and makes you feel lightheaded. Many transitioning smokers need a high nicotine level (18mg to 20mg). The issue with freebase nicotine (the most common form of nicotine in e-liquids) is that the higher the strength, the harsher the inhale is on your throat. Freebase nicotine has a naturally peppery taste so can also interfere with the flavour profile of your e-liquid.
In recent years, the invention of nic salts has made vaping with higher nicotine levels more accessible and enjoyable for many vapers. Originally, nic salts were most commonly used in closed pod kits. Now, they’re available widely in multiple strengths in 10ml bottles in a huge array of flavours.
