"All flavors are Diacetyl free!"
This is the issue, plan and simple -- fraud. Fraud compounded by excuses, lies, more excuses, and cover-up. And at least one business whose immoral owners belong in prison. I will personally cheer when their business has been shuttered and the steel doors slam closed behind these owners.
Here, look for yourself.
This is is diacetyl soup,
http://flavorwest.com/index.php/water-soluble-flavoring/butterscotch.html And the owners unequivocally know this FACT -- they were confronted and provided independent test results
months ago. But did they pull or reformulate this product? No. Do you see a consumer warning on this product? No. The apparent the extent of their action was to remove the fraudulent claim on this product -- though still made elsewhere on their site. And no excuse, this is a flavor manufacturer owned by an ecig company.
Hell yeah, I'm mad. And, hell yeah, I think vapors should be concerned. This has been a ongoing issue for years and years. Behavior like the above is inexcusable, unconscionable, and criminal. This is not about ignorance -- this is about money, profits and the unsuspecting. Hell, microwave popcorn manufacturers removed diacetyl ten years ago -- and yet the above supplier adds in large quantities to a product for direct inhalation? Personally I don't expect to see change until the unscrupulous are sitting in prison.
