IQOS heating technology explained
📌 Similar goals, but different chemistry, sensory experience, and behavioral outcomes.
What They Are & How They Work
Feature IQOS Vaping
Source Real processed tobacco Liquid with nicotine
Heating style Controlled tobacco heating Vaporization of e‑liquid
Aerosol Warm tobacco vapor Cool vapor / mist
Experience Cigarette‑like Unique to vaping
Smoking vs heated tobacco vs vaping
📌 IQOS preserves tobacco taste — vaping offers variety instead.
Sensory Satisfaction & Throat Hit Differences
Cigarette‑like cues matter for switching:
Sensation IQOS Vaping
Tobacco taste memory Strong Limited
Throat hit Warm & direct Softer, varies by device
Aroma Real tobacco Flavors, not tobacco
📌 Heavy smokers often find vaping too soft at first — IQOS feels more familiar.
Nicotine Delivery Speed
IQOS:
• reaches nicotine satisfaction faster
• feels closer to cigarettes
Vaping:
• can be slower depending on device & liquid
📌 Fast satisfaction reduces relapse risk back to cigarettes.
Toxicant Exposure Differences
Risk Factor Cigarettes IQOS Vaping
Combustion toxicants High Lower None (no tobacco)
Flavor chemical exposure N/A Low Varies by product
Smoke solids High Low Very low
📌 IQOS and vaping both reduce many harmful substances vs smoking — but in different ways.
Secondhand Exposure
Cigarette smoke:
❌ pollutes air
❌ persistent in clothing and furniture
IQOS aerosol:
✔️ dissipates faster
✔️ lower emissions vs smoke
Vaping aerosol:
✔️ very low particle residue
✔️ usually mild odor
Secondhand exposure differences
📌 Fire‑free products improve indoor living compared to cigarettes.
Device Care, Maintenance & Convenience
Feature IQOS Vaping
Cleaning Required for blade devices Minimal
Battery life Shorter Often longer
Consumables Tobacco sticks E‑liquid + coils/pods
Flavor changes Limited Very wide selection
📌 Vaping is more flexible — IQOS is more cigarette‑like.
Availability, Regulation & Switching Behavior
Vaping regulations vary widely — flavors and nicotine strengths may be restricted.
HEETS global availability overview
📌 Product access plays a huge role in switching success.

IQOS and vaping both exist for ONE reason:
➡️ to help adult smokers leave behind cigarette combustion
— the main source of smoking‑related harm.
✔️ IQOS = structured tobacco satisfaction
✔️ Vaping = highly customizable and flexible
✔️ Both reduce toxicants vs cigarettes
✔️ Neither is risk‑free
✔️ Both require full switching to be effective
✔️ Intended exclusively for existing adult smokers
Smoking vs heated tobacco vs vapor science overview
📌 The best choice is personal — but the worst choice is continuing to smoke cigarettes.
Fire is the real enemy. Removing it is the real solution.
