If you’re considering vaping, it’s important to understand what it is and how it works. Vaping involves inhaling a vapor created by heating a liquid, often called e-liquid or vape juice, in a device called an e-cigarette or vape pen. The e-liquid is usually a mixture of propylene glycol (PG), vegetable glycerin (VG), flavorings, and sometimes nicotine.

E-cigarettes and vaping devices have become increasingly popular in recent years, particularly among young people. While some people use vaping as a way to quit smoking cigarettes, others use it recreationally or socially. Despite its popularity, there is still much to learn about the long-term health effects of vaping.

One of the main ingredients in e-liquid is vegetable glycerin (VG). VG is a colorless, odorless liquid that is commonly used in the food and pharmaceutical industries. It is also used in cosmetics and personal care products. VG is generally recognized as safe for ingestion, but there is less research on its safety when inhaled.

According to a Johns Hopkins expert, the PG and VG in e-liquids are generally regarded as safe for ingestion, but their effects when inhaled are not yet fully understood. Some studies have suggested that inhaling PG and VG can cause irritation and inflammation in the lungs, but more research is needed to confirm these findings.

It is also important to note that not all e-liquids are created equal. Some may contain harmful chemicals or contaminants, so it’s important to purchase e-liquids from reputable sources and to read product labels carefully. Additionally, some e-cigarettes and vaping devices may be more harmful than others, particularly those that use high-powered batteries or that produce large amounts of vapor.

Overall, if you’re considering vaping, it’s important to do your research and to weigh the potential risks and benefits. While some people may find vaping to be a helpful tool for quitting smoking, others may be better off avoiding it altogether.

Vegetable Glycerin in Vaping

When it comes to vaping, vegetable glycerin (VG) is one of the primary ingredients in e-liquid. VG is a natural chemical derived from vegetable oils, making it safe for vegetarians. It is commonly used in e-liquid to give a thick sensation to vapor and provides a much smoother throat hit than propylene glycol (PG), making it more suitable for sub-ohm vaping ¹.

While VG is generally considered safe for consumption, there are some concerns about its safety when inhaled as vapor. Researchers have found that using e-cigarettes with e-liquid refills containing PG and VG may lead to inflammation of the lungs over a period of time ².

Consuming large amounts of VG, either through vapor or food, may lead to gas and diarrhea, which is usually followed by nausea. Other minor VG side effects include a sore throat and “vaper’s tongue,” a coating on the tongue that lowers taste sensations ³.

However, it’s important to note that VG has not been thoroughly tested for safety when inhaled as vapor. If you’re considering vaping, it’s essential to do your research and understand the potential risks involved.

In conclusion, while VG is a common ingredient in e-liquid and generally considered safe for consumption, there are some concerns about its safety when inhaled as vapor. It’s essential to be aware of the potential risks and to make an informed decision about whether or not to vape.
