diacetyl is supposed to be very harmful. The vendor I get my juice from (I cannot post a link on this forum) swear down they don't use diacetyl. It's about time the FDA came down on eliquid merchants!!!!
Be careful what you wish for...you just might get it.
Based on the current FDA rules, that means each product would need to be subjected to about 500 hours of testing, and bring a cost of about a quarter million dollars. Per product means each and every mix. If you want to make Strawberry flavored 12mg juice, there is a quarter million bucks. If you want to make Strawberry flavored 6mg juice, that is another quarter million. If you want to make Strawberry flavored 3mg juice, another quarter million. Strawberry flavored 18mg juice...you guessed it, another quarter million. Right there, a company is up to a million dollar investment in just one flavor line with only 4 strengths. If they want to do another line of a different flavor in those same strengths, that would be another million bucks. Basically, if they want to only have 5 flavors, and they only want those 4 nicotine strengths, they are looking at a $5,000,000 startup. That is A LOT of money, and I think you will see most(if not all) of your favorite juices disappear. Yes, I know there is a HUGE profit margin on e-juice, but if you want to be a company making 10 different flavors in 6 different strengths(0mg, 3mg, 6mg, 12mg, 18mg, and 24mg), you are looking at $15,000,000 to even get off the ground. Even with the profit margin, that is going to be a HUGE hurdle to overcome. Even if you sell 100,000 bottles of juice a month at 20 bucks a bottle, you are still going to be looking at 7.5 months of being in the red before you even get your testing investment back. That doesn't even take into account the cost of the juice itself, or the logistics of getting it out to the customers. By the time you factor that in, the juice costs are going to skyrocket. If you are fine paying $2 or $3 per mL of juice, you may still have some companies out there doing it, but your selections are going to be very few and far between. On top of that, there will be many people that will not go into vaping, so the market is going to be even more limited. That limited market means even fewer companies are going to be able to come into play. Give that some thought before you hope FDA mandated testing gets forced on juices.
