I’ve been vaping ejuice for almost 3 years now. Its offered both my husband and I the ability to quit smoking cigarettes. I’m dealing with chronic back and shoulder/neck pain, some anxiety, and insomnia. I vape at a 6% nicotine level, can I just add some CBD oil (plain flavored) to my Banana bread ejuice? Without emptying my tank or needing a second tank for the CBD?
