Using the right E Liquid for you.
Posted by Courtney McElligott on Jun 3rd 2016
Choosing the right e-liquid is one of the first decisions every adult vaper makes, and it comes down to more than just flavor. Nicotine strength shapes how a vape feels, and getting it dialed in to your own preference is what makes a setup enjoyable to use day to day.
Understanding Nicotine Strength
E-liquid nicotine is measured in milligrams per milliliter (mg/mL), sometimes shown as a percentage on the bottle. For reference, 2% is the same as 20mg/mL, and 1% equals 10mg/mL. With so many levels available, the range can look confusing when you are just starting out, but the choices fall into a few clear groups.
Common freebase e-liquids are sold in 3mg, 6mg, 12mg, and 18mg. Common nicotine salt e-liquids run higher, typically 20mg to 50mg, because the salt formulation feels smoother at strengths that would be harsh in freebase form.
How Strength Affects the Experience
Nicotine level has a direct impact on how a vape feels, especially the sensation often called throat hit. Higher freebase strengths give a sharper, more pronounced throat hit, while lower strengths feel softer and smoother. If a particular level feels off, moving one step up or down, for example from 12mg to either 6mg or 18mg, is usually enough to find a more comfortable fit.
If a strength is too high for your preference, the vape can taste harsh and feel unpleasant, which sometimes leads people to assume vaping isn't for them. More often than not, the issue is simply the strength, not the device or the e-liquid itself. Stepping down to a lower level can completely change the experience.
Matching Strength to Your Device
The hardware you use matters just as much as the number on the bottle. Pairing the right e-liquid with the right device keeps both the flavor and the draw where you want them.
Pod Systems and MTL Devices
Pod systems and mouth-to-lung (MTL) devices use higher-resistance coils, run at lower wattage, and produce a tighter draw with less vapor. Because each puff vaporizes a smaller amount of liquid, these devices pair well with higher-strength options, often nicotine salts in the 20mg to 35mg range, or mid-level freebase.
Sub-Ohm Tanks
Sub-ohm and direct-lung devices use low-resistance coils, run hotter, and produce much larger clouds. They vaporize far more liquid per puff, so they pair best with lower freebase strengths such as 3mg or 6mg. Using a very high-strength salt in a sub-ohm tank would be overwhelming, so most cloud-focused vapers stay at the lower end.
Finding Your Sweet Spot
There is no single "correct" strength, only the one that suits you. Many adult vapers experiment with a couple of levels before landing on the e-liquid and flavor combination that feels right. For some that takes a single day, for others a few weeks. The goal is a setup you genuinely enjoy reaching for, and a little experimentation with strength, flavor, and device is the surest way to get there.
Frequently Asked Questions
What nicotine strengths does e-liquid come in?
Freebase e-liquids are most commonly sold in 3mg, 6mg, 12mg, and 18mg. Nicotine salt e-liquids run higher, usually 20mg to 50mg, because the salt formulation feels smoother at those levels. Some bottles list strength as a percentage instead, where 20mg/mL equals 2%.
What is the difference between freebase nicotine and nicotine salts?
Freebase nicotine gives a sharper throat hit and is typically used at lower strengths in sub-ohm and direct-lung setups. Nicotine salts feel smoother at higher strengths, which is why they are popular in pod systems and MTL devices. It mainly comes down to the device you use and the kind of draw you prefer.
Which nicotine strength should I use in a pod system?
Pod systems and MTL devices pair well with higher-strength e-liquids, often nicotine salts in the 20mg to 35mg range, because they vaporize less liquid per puff with a tighter draw. If you prefer freebase, a mid-level strength is a common choice for these devices.
What strength works best in a sub-ohm tank?
Sub-ohm tanks vaporize a lot of liquid per puff and produce large clouds, so they pair best with lower freebase strengths like 3mg or 6mg. High-strength nicotine salts are not suited to sub-ohm use and would feel overwhelming.
Why does my e-liquid feel harsh?
A harsh or sharp feel usually means the nicotine strength is higher than your preference, or the e-liquid does not match your device. Trying a strength one step lower, or switching to a nicotine salt for a smoother feel, often makes the experience more comfortable.
How do I find the right e-liquid for me?
Start with a strength suited to your device, then adjust up or down a level based on how it feels. Flavor preference matters too, so most adult vapers try a few combinations before settling on a favorite. Finding the right fit can take anywhere from a day to a few weeks.
