What To Avoid When Making Vape Juice

While there is still much controversy as to the healthiness of vaping over smoking, vaping still offers an array of options and alternatives that make it a better option to smoking. Vape juice is made up of four major ingredients; propylene glycol (PG), vegetable glycerin (VG), nicotine, and flavoring. While ingredients like propylene glycol (PG) and vegetable glycerin (VG) used in making vape juice are federally approved as safe for consumption, additional ingredients like flavor concentrates may be harmful to your health. 

If you are going to be making your own vape juice, you will need to know what ingredients to avoid. Even if you are buying commercial ejuice, there are some ingredients you want to avoid. To do this, you have to first know about vape juice, its components, and the ingredients you should avoid.

What To Avoid When Making Vape Juice

Propylene Glycol (PG)

Propylene glycol or PG is a base ingredient used in making vape juice to give it better flavor and to improve the throat hit. Propylene glycol is already an ingredient used in many of the products we use on a day to day basis. It is FDA approved as safe for consumption. You can find PG as an additive in different medications, and also as an essential ingredient of food coloring. 

Vegetable Glycerin (VG)

Vegetable glycerin or VG is also a base ingredient used in making vape juice. VG on its own is a dense liquid, as a result, it is used to make the vape juice thicker, which in turn allows the vape juice to provide thick and dense flavor. Vegetable glycerin, together with propylene glycol or PG makes for a more enjoyable vaping experience. Just like PG, vegetable glycerin is also used in your everyday commercial products. 

Both propylene glycol and vegetable glycerin are completely harmless. However, you should exercise caution the first time you take vape juice containing them as they may cause allergic reactions. This is especially for propylene glycol. Some of the allergic reactions include dore and tingling throat, irritations on the body. 


Diketones is an ingredient used in food products to give it a creamy and buttery flavor. The same applies to vape juice. Diketones is a substance widely believed to have detrimental effects on humans, and as a result should not be used as an ingredient in vape juice. Most manufacturers do not disclose information concerning using diketones in their products. 

While the testing of diketones is mandatory, it is not the same case as the law goes for inhalable products like vape juice. As a result, it is quite difficult to find the right information about vape juices that are free of diketone. 

What To Avoid When Making Vape Juice


Diacetyl is a harmful substance that is not ideal for consumption, and especially not ideal to be vaped. Diacetyl was used as an additive to create a buttery flavor in microwave popcorn. Diacetyl is directly responsible for “popcorn lung” or bronchiolitis which happens  after inhaling high amounts of the substance for a long time. 

Fragrance Oils 

You should avoid products that contain a large percentage of oils, as well as all oil-based ejuice. This applies if you are making ejuice yourself or buying commercial products. Research has proven that inhaling fragrance oils may affect your respiratory system by damaging your lungs. In the long run, it could lead to chronic lung illness.


Caffeine itself is not good for your health as it does not pass through your digestive system, rather, it goes directly into your bloodstream. When you ingest caffeine in the form of ejuice, it is impossible to control the amount you are taking. Since you cannot control the amount you will be taking in, and too much caffeine can lead to seizures, fast heart rate, even loss of consciousness, it is best to avoid it. 

When choosing ejuice, you should take note of the ingredients and avoid any of the ingredients that prove harmful. If you are making ejuice yourself, it is easier to control these ingredients. In addition to knowing what ingredients to avoid, buying ingredients from reputable manufacturers like flavorah also ensures that you get high-quality ingredients tailored for vaping.
