I am the owner of Doctor E Juice. All E Juice is made fresh to your order. I was able to quit smoking the same day I started vaping but found that some e juice was not so good. I wanted a delicious e juice, but I wanted it to be a more healthy vape. After exhausting research and experimentation I was able to come up with Doctor E Juice....it has Echinacea (as an extra added ingredient if you want it) to promote your immune system and help fight off colds and flu. If you don't want the Echinacea, you don't have to add it and you still get the most delicious, big vapor e juice I have found. Make your order today and decide for yourself. Thanks for your business.
