What the mg numbers mean
Nicotine strength is usually shown in milligrams per millilitre (mg/mL) or as a percentage. Higher numbers mean more nicotine per puff. 0mg means nicotine-free.
Common freebase strengths are 3mg and 6mg. Common nicotine-salt strengths are 25mg and 50mg. Disposables and pods often use salt nicotine because it feels smoother at higher strengths.
Freebase vs salt nicotine
Freebase nicotine gives a stronger throat hit and is typically used at lower strengths in refillable setups.
Salt nicotine is smoother, absorbs faster, and is well suited to higher strengths in low-power disposables and pods — which is why most disposables you'll see are salt-based.
How to choose a strength
As a rough guide, lighter former smokers often start lower, while heavier former smokers may prefer a higher salt strength. Everyone is different, so start conservative and adjust.
Each product page lists the available nicotine strengths so you can match a product to your preference.
