I had to vape 0 nicotine cartos after a spinal surgery, as nicotine can inhibit fusing. My fusion was successful, and I have been vaping high nicotine ejuice again. I have about 6 boxes of the 0 nic cartos, and would like to know if I opened them up and let them dry out, could I use them basically as blanks? I am an RY4 vaper alomost exclusively, so cross tasting wouldn't be an issue. Just wondering if anyone has done this? I use cartos at work instead of tanks due to leakage, etc... Would this work?
