I've recently started vaping, since the amount of products is mind-boggling i just stick to what i can buy in stores. That being said, i've been using a logic pro, and yesterday when i switched out for a new cartridge of the same e-juice, it felt different. Like, an almost instant headache, less vapor, and a bit more effort required to pull, as well as having a hard time defining the taste despite knowing its menthol. So, i thought it might be the original piece, but what are the chances of the coil getting burnt out the moment i put in a new container of e-juice? So my question is, is the e-juice bad or something?
