Understanding Nicotine Strength (mg/mL)
What nicotine strength numbers actually mean, and what to consider before choosing one.
Nicotine strength is listed in milligrams per millilitre (mg/mL) on our product pages — for example, an 18mg/mL e-liquid has 18 milligrams of nicotine in every millilitre of liquid. Here’s what that means in practice.
Higher isn’t automatically “better”
A higher mg/mL means more nicotine delivered per puff, not necessarily a better experience. Many people find a strength that’s too high feels harsh, while one that’s too low leaves them unsatisfied. If you’re switching from a different product or brand, it’s worth starting at a similar strength rather than guessing.
Device type changes how strength feels
The same mg/mL can feel quite different across device types — a higher-powered pod system pulls more liquid (and more nicotine) per puff than a low-power disposable, even at an identical strength. That’s part of why we list nicotine strength on every relevant product page rather than assuming one number suits every device.
A note on regulation
Nicotine vaping products are subject to specific rules in Australia, including restrictions on who can legally purchase them and how they’re supplied. This article is general information, not medical or legal advice — if you have questions about nicotine use, strength, or your obligations as a buyer, speak with a health professional or check current Australian and state-level requirements.
Every order is subject to our Age Restriction Policy, and all vaping products on this site are restricted to adults 18+.
