WARNING

In recent years, searches for “Are e-cigarettes safe?” has seen a 43% year-on-year increase in searches, reflecting the high level of anxiety among consumers around the world about “e-cigarettes causing cancer”. According to the Global Harm Reduction Nicotine Products White Paper, 68% of users have shifted their primary focus from flavor to “e-cigarette oil ingredient analysis” when choosing a vape oil. This blog will show you everything about e-cigarettes and vape juice.

I. VG/PG Safety Controversy: How Temperature Rewrites the Toxicity Scale?
▶ The Toxic Turning Point of Propylene Glycol (PG)
Johns Hopkins University 2024 study confirms:

Below 180°C: PG atomization produces only trace amounts of acrolein (concentration ≤0.12μg/m³)

Above 230°C: Formaldehyde production surges by 800% to 1.1μg/breath
(52.3μg/breath in traditional cigarettes)

▶ Hidden Risks of Vegetable Glycerin (VG)
The latest European Union's "E-Cigarette Safety Standard" (monthly search volume: 4,500+) requires that The latest EU "E-cigarette safety standard" requires:

The acrolein concentration from VG atomization must be labeled.

Ceramic-core devices reduce the release of harmful substances by 67% compared to traditional cotton cores.

Menthol-flavored oils degrade VG 2.3 times faster than fruity flavors.

II.Which vape juice flavour are the most dangerous?
Global Risk Ratings of vape juice flavors in 2024 (TOP5)
Cinnamon: 29% exceeded benzaldehyde (triggers respiratory inflammation)

▶Butter: diacetyl residues up to 82μg/g

▶Menthol: 41% of tested samples exceeded menthol concentration

▶Mango: 17% potential sensitization rate of β-violet ketone

▶Tobacco: nitrosamines detected at a rate of 6 times higher than that of fruit flavors

NOTE: The data was obtained from the global independent Note: Data from INRTLAB, an independent global testing organization

III. User Behavior Alert: Deadly Habits Ignored by 90% of PeopleAccording
To a tracking survey of 10,000 users:

▶37% of users use expired vape juice (with an average expiration of 14 months), and

▶Mixing different brands of vape juice leads to an 89% increase in the leakage rate of the device

▶Vapors who consumed more than 2 ml per day had 3.7 times the concentration of "e-cigarette toxins" in their blood.

IV. How to buy the right vape juice?
▶ Traceability system for raw materials
Check whether the batch number of "USP Pharmacopoeia Grade VG/PG" is published

Requirement to provide a description of the pathway of nicotine synthesis (bio-extracted / chemically synthesized)

▶ Device compatibility testing
Mesh coil atomizers need to be paired with oils with a 70% VG or higher

Cotton core devices are prohibited to use acidic fruit-flavored vape oils (PH value <5.2)

▶ Usage Scenario Management
Nitrogen-filled packaging is required for high-temperature environments (>35°C)

Bottles must be used up within 30 days after opening (Hazard of exceeding the oxidation index > nicotine)
