Many newbies often ask, what is vape juice? Vaping juice or what should more correctly be called vaping liquid, is essentially 2, 3 or 4 basic ingredients & there are sometimes 2 other ingredients that may be used, mixed together to make vaping liquid. So what are these ingredients? Nicotine - this one is obvious to most people but did you know some vapers use vaping liquid without nicotine? We call that 0mg nic (nicotine) juice. Some vapers find that after several months of vaping, that they can reduce their nicotine intake & even give up nicotine altogether, with determination & willpower but still enjoy the hand to mouth action associated with vaping or perhaps just enjoy blowing tasty fog plumes or clouds of vapor. Vegetable Glycerin (VG) - This is often used in food products, medicines, soaps, toothpaste, mouthwash, skin care products/moisturizers, may be used in nightclub fog machines & has been deemed by governments in most countries as GRAS (Generally Regarded As Safe). Propylene Glycol (PG) - You may have heard or read some scary things about this ingredient but like VG above, PG is GRAS, it is used in many household products as an antibacterial cleaning agent, it is found in toothpastes, mouthwash, medicines, soaps, shampoos & some food products. The US FDA allows propylene glycol to be added to a large number of processed foods, including ice cream, frozen custard, salad dressings and baked goods. It has also been used as an aerosol disinfectant in hospitals & is commonly an ingredient in hand sanitizers, it is also used for nightclub fog machines. It is also used in antifreeze where ethylene glycol would be inappropriate, such as in food-processing systems, as a non-toxic alternative. The grade we use (BP grade aka USP grade) is of a much higher grade than that used in antifreeze(which may contain contaminants) & as such is much safer, no vape liquid manufacturer would ever use antifreeze grade PG to make vaping juice. Flavoring - This is the 4th main ingredient used & many of the flavorings used are also used in common food products & GRAS for use in food. However flavorings have not been classified GRAS for inhaling, studies have been done showing very little or no toxicity from inhaling some flavors but more studies are needed. Generally it is accepted by vapers that any risk from flavorings is far less than the risks from smoking tobacco, in the order of 1000's of times safer, in fact standing on a busy road & trying to cross is likely more harmful to you than weeks worth of vaping flavored liquids. Some vapers choose to vape unflavored liquid but they are a minority, the majority of vapers don't all agree on what is the best flavor, since taste preferences vary so much but the majority of vapers enjoy flavored juice. So vaping juice could contain 2, 3 or 4 of the above ingredients, most commonly all 4 in various ratios. Just as vapers like different flavors to other vapers, vapers also have different preferences when it comes to VG & PG ratios & nicotine strength. The 2 other ingredients sometimes found in vaping liquid, are: Water & Alcohol - these are sometimes used in place of PG to thin high % VG liquids or in combination with PG & VG based liquids. Usually if water or alcohol is used, the other will not be used & the percentages used is usually less than 10%, most commonly 5% or less is used of the total volume. It is not common to find these ingredients used in commercial e-liquid or vape liquid, it is more commonly added by the individual vaper using the e-juice. So now you know what is used to make vaping juice or vaping liquid or e-juice or e-liquid or simply juice, all have the same meaning in vaping. Most commonly it is simply called juice but it can come in 100's or 1000's of different flavors, ratios, strengths. It can be thick or thin, strong or be nicotine free, finding the right juice for yourself is half the fun of vaping.
