E-Juice: What is it?

E-Juice, Juice, Vape Juice, whatever you call it, you are probably talking about the same thing.  But what exactly is E-Juice and what purpose does it serve? E-Juice is a liquid that is commonly used in an electronic cigarette / personal vaporizer / mod. The vaporizer / mod heats up the E-Juice and turns it into vapor which is then inhaled. E-Juice typically contains a mixture of Propylene Glycol (PG), Vegetable Glycerin (VG), Distilled Water, Ethyl Alcohol, Nicotine and Flavoring or Extracts. Not all E-Juice has the same ratio of PG to VG mixture, and while some E-Juices use flavoring others may use extracts which are more complex and costly to produce. E-Juice may or may not contain nicotine and comes in thousands of flavors to choose from. The amount of nicotine (strength) will cause the E-Juice to appear darker the more there is.
