So a few month ago I made a batch of Skittles ejuice, and it tastes really, really nice. The only problem is I don't really enjoy vaping 0mg ejuice, I enjoy my nicotine. I normally vape 11mg ejuice, I have 5 10ml bottles of this Skittles ejuice and I'm wondering if I can buy nicotine and add it to the mix and make it 11mg bottles, because that'd be awesome because it's just so nice to vape, and I just have the bottles sitting around doing nothing. If this can be done, could someone direct me in the correct location where to get this? and how much I should use because I believe the nicotine itself comes in different strengths right?
