High Nicotine – What is it in Vaping?

Definition

High Nicotine refers to e-liquids containing elevated concentrations of nicotine, typically 20 mg/mL or higher in Australia. These potent formulations deliver a stronger Hit“>throat hit and faster nicotine satisfaction, making them popular among transitioning smokers and heavy nicotine users. High nicotine e-liquids work by providing concentrated nicotine absorption through vaporisation, offering an intense experience that closely mimics traditional cigarette satisfaction. Available in various forms including freebase nicotine and nicotine salts, these e-liquids serve vapers seeking maximum nicotine delivery while minimising vaping frequency.

Technical Details

High nicotine e-liquids utilise concentrated nicotine solutions, with nicotine salts being the most common formulation for strengths above 20 mg/mL. Freebase nicotine becomes increasingly harsh above 18 mg/mL, whereas nicotine salts maintain smoothness even at 50 mg/mL concentrations. The technical specification involves precise nicotine base mixing with propylene glycol (PG) and vegetable glycerin (VG), typically maintaining a 50/50 or 60/40 PG/VG ratio for optimal wicking in low-power devices.

These e-liquids require specialised heatsink designs in compatible devices to prevent hot spots and ensure even vaporisation. The hybrid connection systems in pod devices are specifically engineered to handle the viscosity and absorption characteristics of high nicotine formulations. Common variations include 20 mg/mL, 35 mg/mL, and 50 mg/mL strengths, with nicotine salts offering faster absorption rates compared to traditional freebase nicotine.

Usage & Tips

When vaping high nicotine e-liquids, use low-wattage devices (typically 5-15W) with high-resistance coils (1.0 ohm or above) to prevent nicotine overdose and harsh throat sensations. Take shorter, controlled puffs rather than deep inhales, allowing the hit to satisfy cravings effectively. Prime new coils thoroughly to avoid dry hits that can deliver concentrated nicotine bursts.

Common issues include throat irritation and dizziness from overuse. Start with 2-3 puffs and wait 10-15 minutes before continuing. Store high nicotine e-liquids in child-proof containers away from heat and light to prevent degradation. Never use these concentrations in sub-ohm or high-power devices, as this can lead to nicotine poisoning. Australian vapers should note that nicotine concentrations above 100 mg/mL require prescription for personal importation.

History & Context

High nicotine e-liquids emerged prominently with the introduction of nicotine salt technology by Pax Labs in 2015, revolutionising the Australian vaping market. This innovation allowed smokers to transition more effectively, as previous freebase nicotine limitations capped practical concentrations at 18-24 mg/mL. The evolution from traditional high VG sub-ohm vaping to high nicotine pod systems represents a significant shift toward smoking cessation-focused vaping, particularly relevant in Australia’s restrictive regulatory environment where effective nicotine delivery remains crucial for harm reduction success.
