So i just started vaping, a friend gave me a bunch of vape juice because he no longer use it he told me that he don't know what has nicotine in it . can anyone help me i define the one without nicotine in it. I provided a bunch of pictures down below... If you guys could circle the one with nicotine so i can tost it that would be great. I took pictures of both sides and front of all bottles . Please feel free to zoom in to the "mg"
