Hey Roger! Here's our disclosure on the website - we put it on every applicable product...
*All liquid containing "custard notes" from ALL VENDORS (including Nicoticket LLC) contain some combination of Diacetyl, Acetoin, and/or Acytyl Propionyl (collectively known as "Diketones").
Our liquid does *not* contain Diacetyl, but it *does* contain both Acetoin and Acytyl Propionyl. It is *impossible* to produce "custard notes" in eLiquid without Diketones. Although the inhalation risks associated with Diacetyl are known at high concentrations, research is either non-existent or inconclusive regard to the long-term inhalation risks of Diacetyl at comparatively low levels of concentration. Virtually no longitudinal research exists with regard to the long-term health effects of vaping alternatives to Diacetyl (such as Acetoin, or Acytyl Proptioyl). As with all eLiquid regardless of the types of flavoring used, the user accepts the all liability and risk associated with vaping. ANYONE WHO SAYS VAPING IS TOTALLY SAFE IS IGNORANT OR OUTRIGHT LYING. Our position - even custard eLiquid containing high concentrations of Diacetyl, a chemical compound with known inhalation risks at high concentrations, is safer than a cigarette. Despite the fact that POISON was clearly printed on every pack, we smoked anyway. Users wishing to avoid diketones entirely should avoid ALL liquid containing custard notes from ALL vendors! Users wishing to avoid all risk should avoid vaping. Vape on, my friends… vape on.
We could have an interesting discussion about the safety concerns of Diketones. It's certainly a hot topic, and one that is about to get hotter in the near future. There is some speculation that Diacetyl may be produced with the other diketones are heated...
SEE HERE. That's far from scientific, but, it gives reason for pause when considering vapes that contain custard notes.
