Laying Bare The Real Truth – Propylene Glycol In Electronic Cigarettes

Warnings issued by big tobacco and big pharma about the dangers of propylene glycol are not grounded in scientific reality or backed by scientific research. After a study in mice at the University of Chicago’s Billings Hospital in 1942, it was thought that propylene glycol when inhaled might cause such diseases as pneumonia and other illnesses affecting the respiratory system. To determine long term effects followup studies on money and other animals were conducted. This larger study produced results that showed no ill effects from propylene glycol in the lungs.

The FDA and tobacco companies were quick to cry “danger’ and point to an ingredient that has been judged safe to use for many years. There is primary truth that is totally ignored in the warnings. 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.

A fantastic amount of information can be found online but it’s important to know who you are listening when accepting information as fact. Baby wipes contain PG and it’s difficult to imagine the FDA making claims that a product freely allowed for use on infants is now unsafe for adults. The PG delivered to the user by the best electronic cigarettes is minimal. Some e-liquid suppliers use glycerol as a base for their nicotine solution rather than propylene glycol.

Many of us carefully read labels on foods we buy. We know some food additives used for years to add healthy color to canned foods were later found to carry some health risks. Those on a low sugar diet must scan the food label for sucrose, fructose and corn syrup as well because they are all forms of sugar.

Thirty years ago the FDA announced a ban on saccharin and any products containing saccharin. The public was in a panic and threw out their boxes of sweet and low while manufacturers hustled to change the recipes of their food products. Only later was the public told the truth.

What the FDA didn’t tell the public was that the research did not apply to people. The mice had been given huge doses of saccharin daily. Adjusting the amount to that needed for a person to develop cancer would require the person to consume at least 400 cans of diet cola every day for months. Today, saccharin is once again fully available for sale to the public.

PG is necessary as an ingredient in e-cigarettes to deliver the vapor smokers want. There is no scientific proof that e-cigarettes containing propylene glycol pose a danger to the smoker. That is the truth no matter how much effort big tobacco puts into discrediting a competing product.
