Difference PG vs VG E-juice? Safe? Side Effects?

E-juice is created with the mixture propylene glycol abbreviated PG, vegetable glycerin abbreviated VG, nicotine, and flavoring. Sometimes water or a sweetener will be added too. The amount of PG to VG will vary by brand. We’ll answer common questions like how do PG and VG affect vaping? Is it safe and what are the side effects? Vegetable glycerin is a lot bigger thicker than propylene glycol. The consistencyis are similar to cooking oil while propylene glycol is thinner like water. You can see the PG e-juice just flows right through while it’s a little bit of a struggle for VG. E-juice with more PG carries the flavor a lot better and delivers a greater hit to the back of your throat. Since VG has a greater specific gravity, e-juice with more VG will generate more vapor.


One challenge presented is due to the viscosity (thickness) of vegetable glycerin. Clearomizers and cartomizers will have a harder time vaporizing it. It could cause a build up around the coil faster that clogs the atomizer. VG e-juice works well in dripper style atomizers. Increasing nicotine levels increase the intensity with which it hits your throat while the flavor will be more distinct with less nicotine. This is the same e-juice flavor at 0 milligrams and at 18 milligrams. Overall it comes down to preference, but remember VG is for Vapor. PG is flavor and throat hit. You can also get 50/50 e-juice to balance the two.


Are PG and VG dangerous chemicals in normal vaping quantities? It is important to note that both PG and VG are often used in food, medical, and pharmaceutical products. In fact, asthma inhalers use PG as well. FDA opinions on Propylene glycol indicates that it is generally recognized as a non hazard at the levels the it is normally consumed. Researching the chemical, I discovered this excerpt from the FDA.   “There is no evidence in the available information on propylene glycol and propylene glycol monostearate that demonstrates, or suggests reason to suspect, a hazard to the public when they are used at levels that are now current or that might reasonably be expected in future.” Web Source: http://www.fda.gov/food/ingredientspackaginglabeling/gras/scogs/ucm261045.htm

Vegetable glycerin is organic and made from plant oils, it’s a sugar substitute used to sweeten food.

The probability of being allergic to propylene glycol is low and an infrequent occurrence for vegetable glycerin. The fact that these two chemicals are used in other household products makes it likely that you know already if you’re allergic to them or not. Some of the symptoms of propylene glycol allergic reaction include eczema, throat irritations, and nausea. IF you find you are allergic to them, then switching to 100 percent vegetable glycerin should resolve these symptoms. Side effects for PG and VG include: dry mouth, sore throat, and increased thirst; which all can be cured by drinking more water. The symptoms are usually short term in nature and quickly subside after you get use to vaping. When starting out vaping, they could last a few days to a week or until the body adapts to e-juice. Remember not everybody will experience these side effects. Sometimes switching from tobacco cigarettes to electronic cigarette can be confused with e-juice side effects, but withdraws symptoms from quitting cigarettes.

Second-hand Smoke: What is it? Is it Dangerous to your Health?

Second-hand smoke a combination of two known sources of the smoke. The lit or burning end of the cigarette, and the second is the toxic plume released into the air by the smoker. Research has shown that second-hand smoke contains over 7000 different chemicals. Of these, hundreds of them are known to be toxic. Of that smaller batch of hundreds, seventy of them are known carcinogens. (Cause Cancer). One government report, released by the surgeon general estimates that since 1964 over 2.5 million adults who were non-smokers, died due to the repeated exposure to second hand smoke.

It is important to note that there is no risk-free level of exposure to second-hand smoke.

  • Secondhand smoke causes numerous health problems in infants and children, including increasing severity and freqency of severe asthma attacks, respiratory infections of the lungs, ear infections, and sudden infant death syndrome (SIDS).
  • It has been estimated that smoking while pregnant results in more than 1,000 deaths per year.
  • Some health conditions that are caused by secondhand smoke include an increased risk of coronary heart disease, stroke, and even lung cancer.


Here is a diagram that shows some of the negative effects of smoking cigarettes.
