aldehyde study

To flavor or not to flavor?

That time-tested question prevails again.

Depending on which side of the political aisle you stand, the fear of ingesting dangerous chemicals feels like a legitimate threat. Others? They believe its overblown health propaganda.

For certain, there have been numerous studies conducted on the subject.

The overall conclusion?

Take your pick.

One study indicates aldehyde emissions in e-cigarettes can be as life-threatening as firing up traditional nicotine-based cigarettes.

Another study suggests aldehyde emissions are actually 589-fold lower than previously reported.

There is one study stating dry puffs increase chemical output.

Another study says it doesn’t.

To believe or not to believe.

That is the true question.

There is little questioning the act of inhaling any level of aldehyde can be harmful. But to what degree?

Consider the air we breathe, the water we drink and the food we eat. What is pure?

As defined by, an aldehyde is “any of a class of organic compounds containing the group −CHO, which yields acids when oxidized and alcohols when reduced.”

Is it potentially harmful?

One study says yes.

Another says maybe.

Another says no.

Hmmmmm …

A study conducted in 2016 compared flavored and unflavored e-liquids, concluding the highest levels of aldehyde emissions were detected with watermelon, blueberry, and coffee flavors.

Curiously, no aldehyde emissions were detected when vaping with unflavored liquids.

That finding was stunning in that it rebuked the theory dry puffs were the main culprit for high aldehyde levels.

By the way, yet another study indicated outdated e-cigarettes produced nearly 100 percent more aldehyde emissions than new devices.

Several studies seem to agree, however, aldehydes are produced during the thermal degradation of e-liquids, particularly two of its main ingredients, glycol, and glycerol.

At least there’s something two or more studies agree on.

But if you have additional questions, you can bet there is a study for that – and one that will support whatever your particular point of view is. That’s not exactly science, but it is unfortunate.
