ALL Nicotine IS COMING from CHINA so if you find Nicotine that is grown, processed and turned into liquid Nic here in the USA please let us all know about it. Not trying to be smart but we have been all through this in other threads about where juices come from, I'm pretty dam sure that no one and none of our vendors are making juices with American made Nic juice, therefor all the vendors that are calling there all USA JUICES made in the USA are pretty much full of it, there Nic is all coming from overseas, China or Belgium, mostly all Chinese made. Are the juices than mixed here in the USA yup many of them are and with PG.VG, and flavorings and other ingredients that come from here or other places, so believe it is mixed here when you see all USA made juice but don't for a second believe there Nic in that juice is coming from the USA. Even the Big Pharma companies are buying juice from overseas. There are few juice suppliers that are using 99.9 Nic most are using 99.7 because of the cost difference and availability, some of the Nic I have seen used is of a very poor grade, while others I have seen is of a very high grade. It does make a difference in your bottom line on how the final juice product turns out from my findings. Currently I'm DIY'ing with some very good 99.9 clear as water Nic and my DIY juice is really coming out very good, there are some other threads about this if you search around a bit
