Exposing The Honest Truth – Propylene Glycol And Electronic Cigarettes
There is little reality in the efforts of big tobacco and big pharma to portray the use of propylene glycol as a danger ingredient in electronic cigarettes. In 1942, studies at the University of Chicago’s Billings Hospital seemed to show inhalation of vaporized propylene glycol might cause pneumonia and other respiratory diseases in mice. Later studies to follow up were conducted on monkeys and other animals in an attempt to understand long term effects. The results of the extended testing showed no ill effects or potential for accumulation of propylene glycol in the lungs.
Shouting “danger”, the FDA and tobacco companies point to an ingredient that has proven safe through many years of use. The misinformation about propylene glycol ignores one very important fact. We know e-cigarettes are safer than tobacco products when inhaled. We know smoking almost anything is safer than smoking tobacco.
Propylene glycol in e-cigarettes dilutes the nicotine in a solution that can be deliver to the smoker as a vapor. PG is commonly used as a food additive and is an ingredient in many products we buy. Propylene glycol is the substance that produces the fog generated by fog machines.
The warnings of the dangers of PG do not come from researchers, doctors or scientific journals. Online sites issuing warnings are full of anecdotal (and seemingly imaginary) stories and are blogs often devoted to conspiracy theories. Several comments contain the statement that “propylene glycol is antifreeze”. Well, no, it isn’t. That would be ethylene glycol. Natural healing sites and anti-smoking groups are also quick to talk about potential danger of the use of PG.
There is a vast array of information available on the internet. It’s important to remember that not all information is factual or backed by experience, research or knowledge. Baby wipes contain propylene glycol and it’s odd the FDA would allow a dangerous substance to be used in products for infants, isn’t it? Very little PG is ingested in the vapor inhaled by an e-smoker. There are some producers who sell e-liquid with a base of glycerol but PG is the most common ingredient in e-cig solutions.
Consumers are more conscious of food additives and harmful ingredients in the foods they eat than every before. Looking at the ingredients on products you buy is a smart thing to do. We know to look carefully at labels when buying products low in sugar. Ingredients such as sucrose and fructose and various types of “syrup” may be listed and each of those ingredients is sugar.
The saccharin scare thirty years ago is a valuable example of the folly of acting on incomplete information and drawing incorrect conclusions. The FDA banned saccharine which was a very popular sweetener used as an additive in many packaged foods and. The FDA stated saccharin had caused cancer in mice and panic ensued. Companies lost a lot of money in changing the ingredients in their products and the public tossed out boxes of Sweet and Low which was a popular saccharin product.
To induce cancer in mice who ingested saccharin researchers had provided extremely high doses of the ingredient. The scientific “proof” offered by the FDA was rejected by the scientific community. The affected mice were given a daily dose of saccharin that could only be ingested by a human drinking 400 cans of diet cola a day for many months. Saccharin is totally available to the marketplace today.
Propylene glycol is a necessary ingredient for delivery of e-cig vapor. There is no evidence ths PG causes any danger to electronic smokers despite the efforts of tobacco companies worried about the competition.
