Propylene glycol (PG) has a long history of safety and effectiveness as an additive to everyday products. Many pharmaceuticals use propylene glycol as part of a solution or suspension for the safe delivery of medication. Many beauty products and cosmetics include propylene glycol and it is frequently added to pet food and baby products, such as baby wipes. An inert, odorless, and non-toxic chemical, propylene glycol has recently received attention as the primary ingredient in e-cigarettes and the public has clamored over safety concerns regarding vaping, or the usage of e-cigarette vapor, and the long term effects of this chemical on the human body.
Propylene glycol is recognized by the U.S. Food and Drug Administration as “Generally recognized as safe”. This means no long term effects of harm have been identified when using this chemical normally. It is nearly impossible not to interact with propylene glycol on a daily basis, as it is an inert additive in many products and is an inexpensive option to use for the delivery of common medications and treatments. No harmful effects have been observed over the decades of usage of propylene glycol on a daily basis.
Beyond the current body of knowledge, vaping and cigarette e-juice have been investigated as a possible defense against the germ filled winter air. A ground-breaking study has shown even in small dosages, propylene glycol is effective at killing common winter viruses, such as pneumonia and influenza, suspended in the air. These viruses often remain potent in indoor air during the winter and are cycled through buildings by closed air systems, causing the mass spreading of winter colds and flu. Many chemicals studied that effectively kill these viruses are toxic, harmful, or irritating to human lungs, making their use in daily like impossible.
Unlike these harsh chemicals, propylene glycol is harmless to humans and can be inhaled at high concentrations without danger. Due to germicidal emissions produced by small quantities of propylene glycol, extremely small quantities can be used to sterilize large amounts of air, reducing the risk of common winter illnesses. Many scientists have begun investigating whether all day vaping can reduce the risk of catching these common viruses, and while the results remain to be seen, there is little question that propylene glycol is a safe chemical for daily use.
While thousands of studies have isolated cigarette smoking as harmful and toxic for long-term use. E-cigarettes provide a safer, less polluting alternative. With no second hand smoke and a complete absence of harmful additives, such as tar, it is clear that e-cigarettes provide smokers with a more pleasant and less harmful smoking experience. It is exciting to consider that vaping could be the key to preventing winter illnesses such as influenza, a disease known to kill thousands each year. Regardless of whether you are a decades-long smoker or one simply smoking during social interactions and experiences, it pays to look into the benefits of vaping. Propylene glycol in e-cigarettes, as well as other commonly used household products, is considered safe for daily use. The human body can easily metabolize this additive into natural products and energy sources without harm to the body. Harmful side effects are extremely rare and less than other cigarette additives. You can rest assured that there is little chance of harm from propylene glycol.
