Clearly all terpenes are not equal when eaten, used in suppositories, rubbed on the skin, or inhaled.
Terpenes also break down and readily change form around 710F, and some of the biproducts are known carcinogens.
The effects burning the terpenes in the concentrations seen in plant material and vaporizing those terpenes in concentration are also different, as the poison is always in the dosage and some of the terpenes will strip paint and sanitize toilet bowls in concentration.
The truth is that there haven't been studies conducted beyond the concentrations used in aroma therapy, and many of the terpenes don't even have MSDS sheets because they have been considered, herbs, spices, and misc flavors.
I told myself that I would quit smoking cannabis when I needed glasses or went crazy, which in my case came in the form of mild COPD, so I switched to dabbing and I'm convinced that making the decision to smoke cannabis, is making the personal decision to at least expose yourself to COPD.
Based on my COPD improving some and not getting worse, I've come to believe using pure unadulterated concentrates with a temperature controlled electric nail is a better option.
Some of the concentrates samples that people give me have terpenes added back or terpenes added, which I would prefer as an adulterant as opposed to dilutants, if some care is given to what those terpenes are, and their content is kept close to the levels normally encountered in plant material.
Terpenes have their own medicinal effects, as well as adding flavor and aroma, but none of the terpenes that add flavor and aroma are particularly smooth to vaporize, so over doing it adds aroma, but at the expense of harshness.
I suspect that time will show that vaporizing and inhaling VG, PG, PEG, MCT, squalane, triethyl citrate, et all, brings with a whole different set of health issues long term.
Pages back GRAS was mentioned, but GRAS is heavily influenced by usage.
For instance, the mineral oil that started this debate is GRAS in food stuff below 5 ppm as a release agent, and you will find Sulfuric Acid on that same list.
I think we can all agree that inhaling either is insalubrious, so its GRAS status is moot.
What is needed, is long term studies in the usage at hand, which we ostensibly won't have for some time.
An age is called Dark not because the light fails to shine, but because people refuse to see it.
Believing is seeing and ignorance is bliss until it bites you in the ass!
Fervor is the weapon of the impotent. The harder the sell, the poorer the product.
Alas, my ignorance abounds; the more I've learned, the less I know that I know..........
Thou shalt seek and respect the opinions of operators, even unto the third helper, for theirs is a wisdom unknown to technicrats.
Wise men learn more from fools, than fools from wise men.
In my dotage I finally discovered that the secret to putting on pants both legs at a time is sitting down.
