20mg Nicotine – What It Means in Vaping & Who It’s For

20mg Nicotine – Glossary Entry

Definition

20mg nicotine refers to an e-liquid that contains 20 milligrams of nicotine per millilitre (20 mg/mL). In Australia this is the maximum legal strength for retail nicotine e-liquids under the current Therapeutic Goods Administration (TGA) regulations. Designed for mouth-to-lung (MTL) and pod-style devices, 20mg nicotine e-liquids deliver a cigarette-like Hit“>throat hit and rapid nicotine satisfaction, helping smokers transition to vaping while keeping intake within legal limits.

Technical Details

Measured as a weight-to-volume ratio (mg/mL), 20mg nicotine e-liquids are usually formulated with nicotine salts. Salts use benzoic acid to lower pH, producing a smoother inhale at high concentrations compared to traditional “freebase” nicotine. Most 20mg juices come in 30 mL or 60 mL bottles, yielding a total of 600 mg or 1,200 mg of nicotine respectively. They are compatible with low-wattage devices—typically 8–18 W—powered by 18650, 21700, or built-in batteries. Variations include 50/50 PG/VG blends for tight-draw pods and 60/40 or 70/30 blends for slightly airier setups. Always check that the bottle displays the correct concentration (20 mg/mL) and child-resistant cap to comply with Australian standards.

Usage & Tips

  • Start Low, Puff Less: Begin with short 1–2 second draws; 20mg delivers nicotine quickly, so chain-vaping can cause dizziness or nausea.
  • Match Your Coil: Use coils ≥1.0 Ω and restrict airflow for best flavour and throat hit. High-wattage sub-ohm coils will make 20mg harsh.
  • Storage: Keep bottles in a cool, dark place away from children and pets. Nicotine oxidises faster once opened; finish within 3–6 months.
  • Common Issue – Leaking Pods: Ensure the Thread“>510 thread or pod seal is clean and seated properly; over-filling or altitude changes can flood the coil.
  • Safety Note: If you feel unwell, switch to a 0mg nicotine option temporarily and consult a health professional.

History & Context

Prior to October 2021, Australians had to import nicotine e-liquids under personal importation schemes. The TGA’s prescription-only model capped retail strengths at 20mg/mL to balance cessation support with harm reduction, aligning Australia closer to European limits while remaining stricter than the US 50mg standard.
