Yep, and?
Have you read an MSDS for the ingredients in Coke?
The MSDS assumes full concentrations and factory type exposures.
Imagine using a candy flavoring with a violent flashpoint above 25F? That is what the document shows. How many cooking
devices has the flavoring company replaced?
The practice of saying something is bad at full strength so any amount is bad is not reasonable. You could do so for nic and nearly any bottled beverage. Heck toothpaste by the same reasoning is horrible stuff.
Personally, I would not use it. But I do not drink soft drinks. And I am wary of any acatate. It has more to do with specific health conditions I have instead of fears of the substance itself.
Think about the dosage percentage. Consider your options. Make a reasoned choice. But don't forget inhalation is the quickest route to the blood stream outside of injection. Even drinking too much water will kill you just as well as drinking too little. (Too much is tougher to do by far)
And while you are drinking that water consider the chlorine and lime in it and look those MSDS's up.
