Exhale – What is it in Vaping?
Definition
“Exhale” in vaping refers to the act of expelling vapour from the lungs after drawing on an e-cigarette, eGo style device, or e-shisha. It is the second half of the vaping breath cycle: inhale (draw vapour in), pause (optional flavour savour), exhale (release visible cloud). Unlike cigarette smoke, exhaled vapour consists mainly of water, propylene glycol, vegetable glycerine, and trace flavour compounds from the e-liquid or e-juice. The exhale is where cloud size, flavour aftertaste, and nicotine absorption are judged, making it a critical part of the overall vaping experience for Australian vapers.
Technical Details
Exhaled vapour temperature ranges 20–35 °C, matching body temperature, and quickly cools below 25 °C within 30 cm of the mouth. Particle size averages 0.3–0.5 µm, allowing rapid dispersion so visible clouds dissipate in 5–10 seconds under normal indoor airflow. VG-heavy e-liquids (>70 % VG) produce denser, slower-fading clouds, while PG-dominant mixes (<50 % VG) yield thinner, faster-vanishing exhales. Airflow control rings on eGo style tanks let users tune exhale resistance; wide-open settings create airy, cloudy exhales, whereas tight draws mimic cigarette-style mouth-to-lung exhales. Sub-ohm coils (<1 Ω) and higher wattages (40–80 W) amplify cloud volume, whereas high-nicotine or nicotine-salt e-juices encourage shorter, discreet exhales to limit Hit“>throat hit.
Usage & Tips
For flavour-chasers, slow 3–4 second mouth-to-lung exhales through the nose and mouth maximise taste receptors. Cloud-chasers should exhale straight ahead with relaxed jaw and steady breath to avoid turbulent dispersion. If vapour lingers and sets off smoke alarms, switch to lower-VG e-liquid or exhale toward an open window. Coughing on exhale usually signals overly high nicotine or wattage—reduce power or choose a milder e-juice. Always exhale away from bystanders and avoid enclosed public spaces to maintain courteous vaping etiquette in Australia.
History & Context
Early cig-a-likes (2006-2009) produced wispy, near-invisible exhales. The 2010 eGo stylebattery and clearomiser revolution introduced thicker vapour, turning the exhale into a visible signature. By 2014, competitive “cloud comps” in Australia and globally elevated exhale size to sport status, driving high-wattage devices and max-VG e-liquids still popular today.
