I'm pretty sure you can, but I'm new to all this. I ordered some 15ml bottles of 0mg juices only to realize I really do like the TH that Nic seem to add and still need some Nicotine in my juice. Anyone have any good advice on how to go about this. Can you order just nicotine from some suppliers? I'm hoping to end up with about 8mg of Nicotine when all is said and done. Thanks for any help...
