Can I dilute my 50/50 store bought juices with straight VG and lower the PG level so as not to waste the juices I have already purchased? If so can someone tell me how to do this? I hate to throw out all of my good juices but the PG is irritating. I know its the PG because I have asthma and have had problems with thrush and my inhaler. Thank you all. I am new to the Forum and to vaping. 18 days since I quit a 25 year PAD nasty habit.
