Vaping Safety: Is Propylene Glycol Safe to Use?
Are you wondering if propylene glycol (PG) is safe to vape? With the growing popularity of vaping, it is important to understand the potential risks associated with inhaling vaporized chemicals. High-quality vapes with PG are generally considered safe and non-toxic as long as they are free from harmful additives. However, low-quality vapes and electronic cigarettes that contain nicotine and chemicals like diacetyl and vitamin E acetate can cause serious health issues, including damage to gum tissue and lung disease.
Research has shown that using e-cigarettes with the e-liquid refills containing PG and vegetable glycerine (VG) may lead to inflammation of the lungs over a period of time. While PG is non-toxic and commonly used to carry flavor in food products, as an ingredient in food coloring, and also used as an additive in various medicines, it can produce a much stronger throat hit than VG, mimicking the sensation of smoking. Due to this, you will rarely see an e-liquid with a higher PG ratio of 70% as the vape becomes too harsh. It has a thinner consistency than VG.
It is important to note that the safety of vaping is still being studied, and the long-term effects of inhaling vaporized chemicals are not fully known. However, by understanding the potential risks associated with vaping and choosing high-quality vapes with PG that are free from harmful additives, you can make an informed decision about whether or not vaping is right for you.

If you’re a vaper, you’ve probably heard of propylene glycol (PG). It’s one of the main ingredients in e-liquids and is responsible for carrying the flavor and nicotine in your vape juice. But what exactly is propylene glycol, and is it safe to vape?
Propylene glycol is a clear, odorless liquid that is used in a variety of products, including food, cosmetics, and pharmaceuticals. It’s also used in antifreeze, which has led to some concerns about its safety. However, the type of propylene glycol used in e-liquids is food-grade and safe for human consumption.
When you vape, the propylene glycol in your e-liquid is heated and turned into vapor. This vapor is then inhaled into your lungs, where it is absorbed into your bloodstream. While propylene glycol is generally recognized as safe by the FDA, some people may experience side effects from vaping it.
Some of the most common side effects of vaping propylene glycol include dry mouth, sore throat, and increased thirst. In rare cases, it can also cause allergic reactions or respiratory irritation.
If you’re concerned about the safety of propylene glycol, there are alternatives available. Vegetable glycerin (VG) is another common ingredient in e-liquids and is considered to be safer than propylene glycol. VG produces thicker vapor and has a slightly sweet taste, but it can also cause buildup on your coils and reduce the lifespan of your atomizer.
In conclusion, propylene glycol is generally safe to vape, but it may cause side effects in some people. If you experience any adverse reactions, you may want to switch to an e-liquid that uses vegetable glycerin instead.
