I am still really new to vaping, juices and such so I hope this doesn't come out as a silly question, but I want to be safe. My question is about mixing store bought juices that already are mixed with PG, VG and nic, not about diy juice that is mixed from scratch. Forgive me please if this has been asked 1000 times. I did do a search here and found nothing and also on google and got a lot of diy answers but nothing that answered my question. Ok, so what is my question? lol. Is it safe for me to mix two or more premixed ejuice to make a new juice or am I raising levels of nic, pg, or vg? I am having a bit of a time to find a juice that I can consider my all day vape. I have one that comes very close.. that is Deep Thought from Vapor Chef. I just want another that I can switch off with. I do not have a place where I can taste and I am hesitant to just blind order based on others reviews. I know I am too noobish to think about diy but is it safe to mix two premade batches of juices to come up with new flavor? As an example: coffee flavor (50/50 with 12mg nic) with say chocolate flavor (50/50 with 12mg nic). Is this a safe practice or will I be also changing the values of the nicotine, vg and pg? Sorry, chemistry is not my strong suit.
