3mg Nicotine – What is it in Vaping?

Definition

3mg Nicotine refers to an e-liquid formulation containing 3 milligrams of nicotine per millilitre of juice—often written “3 mg/mL” or simply “3 mg.” It sits at the lighter end of the nicotine-strength spectrum, delivering a mild Hit“>throat hit and subtle satisfaction that mimics the act of smoking without overwhelming the user. Popular among Australian vapers who have stepped down from higher strengths or who use higher-wattage devices, 3 mg nicotine e-liquids balance flavour clarity with a gentle nicotine delivery, making them ideal for direct-to-lung (DTL) vaping styles and sub-ohm coils that produce large clouds.

Technical Details

Nicotine concentration is measured in milligrams per millilitre; therefore a 60 mL bottle labelled “3 mg” contains a total of 180 mg of pharmaceutical-grade freebase nicotine suspended in a carrier base of propylene glycol (PG) and vegetable glycerin (VG). Most 3 mg juices use a 70 VG / 30 PG ratio to suit cloud-focused setups, but 50/50 and salt-nic versions also exist. Because sub-ohm atomisers vaporise more liquid per puff, 3 mg provides roughly the same blood-nicotine spike as 6–12 mg in a mouth-to-lung tank, yet with smoother throat feel. TPD-compliant 10 mL bottles in the EU max out at 20 mg, so 3 mg is well within legal limits and is often sold as a “doubler” or “short-fill” in Australia, leaving space for a nicotine shot to be added later.

Usage & Tips

Pair 3 mg liquid with devices running 0.15–0.4 Ω coils at 40–80 W for optimal flavour and vapour production. If throat hit feels weak, increase wattage slightly or switch to a 50/50 blend; if it’s too harsh, lower wattage or open airflow. Always prime new coils for 5–10 minutes to avoid dry hits. Because 3 mg is low strength, chain-vaping can still lead to nicotine over-consumption—pace puffs and stay hydrated. Store bottles in a cool, dark cupboard; sunlight oxidises nicotine, turning the juice peppery. Finally, keep 3 mg e-liquid away from children and pets: while mild, accidental ingestion can still cause nausea and dizziness.

History & Context

When sub-ohm tanks exploded onto the market circa 2014, vapers discovered that 18–24 mg juice delivered an unbearably harsh hit at 60 W. Manufacturers responded by standardising 3 mg as the “sweet spot” for cloud chasers, cementing its place in every e-liquid line. Today, 3 mg is Australia’s best-selling strength, bridging the gap between 0 mg nicotine and higher 6–12 mg options.
