📌 FIIT sticks are not risk‑free — they still contain tobacco and nicotine.
Internal Construction — What’s Inside FIIT Sticks
FIIT structure consists of multiple engineered segments:
Component Function
Tobacco plug Main nicotine and flavor source
Aerosol former (glycerin) Creates inhalable vapor
Filter segments Cool and refine aerosol
Polymer cooling section Controls heat and draw resistance
Paper wrapper Structural stability
Heated tobacco stick structure comparison
📌 Glycerin is critical — it vaporizes, replacing smoke.
Tobacco Material — Composition & Role
FIIT uses reconstituted tobacco:
• blended tobacco leaf
• ground and sheet‑processed
• optimized for heating rather than burning
This ensures:
✔️ consistent aerosol
✔️ reduced harshness
✔️ stabilized nicotine delivery
Aerosol Formers — How Vapor Is Created Without Fire
FIIT includes food‑grade glycerin (E422):
• evaporates under heat
• forms visible aerosol
• carries nicotine and flavors
📌 Aerosol is not water vapor — it contains nicotine and tobacco substances.
Filter System — Cooling & Purification Design
Filters reduce temperature before aerosol reaches the mouth:
Filter Segment Purpose
Acetate filter Basic filtration
Cooling segment Reduces heat via thermoplastic film
End filter Shapes mouthfeel
This helps prevent irritation and improves draw consistency.
Flavor Additives — Sensory Diversity
FIIT uses:
• tobacco extracts
• menthol derivatives (in cooling blends)
• aromatic flavor mixtures
Goal:
✔️ replicate cigarette‑like feel
✔️ support switching preference
✔️ enhance sensory acceptance
📌 Flavors do not reduce nicotine addiction or toxic exposure.
Temperature Interaction — Designed for Lil Solid Heating
Lil Solid’s conduction heating warms the tobacco plug steadily.
📌 Wrong device → unpredictable heating + structural damage risk.
Toxicant Formation — What Science Shows
FIIT avoids combustion → significantly lower levels of:
• tar
• carbon monoxide
• polycyclic aromatic hydrocarbons (PAHs)
But exposure still exists:
⚠️ tobacco‑derived chemicals
⚠️ addictive nicotine
⚠️ aerosol toxicants at reduced levels
Healthier vs smoking?
Only if fully replacing cigarettes.
📌 These are self‑reported perceptions — not guaranteed medical effects.
Final Conclusion — Ingredients Shape Both Satisfaction and Risk
✔️ FIIT sticks are purpose‑built for heating, not burning
✔️ Tobacco, glycerin, and filtration design support switching success
✔️ Nicotine remains addictive — risks continue
✔️ Full replacement of cigarettes may reduce exposure
✔️ Quitting all tobacco & nicotine = safest choice for health
📌 If FIIT improves switching durability, exposure falls — if not, smoking continues.
