The testing on R-134a must be done, even if only to set standards to make sure no one's using it. Do you really know where your buddy's oil came from?

Hmm... I'm not sure where you get that impression. The only part of this that is correct is the fact that you don't need a Section 608 EPA certification to purchase "substitute refrigerants" such as R134a. This is from the EPA's FAQ:
Although the replacement refrigerants, such as R134a, don't contain (or have very little) ozone-depleting substances, we in the HVAC/R are to treat them as so, and any venting is a big no-no. Now there is "green talk" about the "global warming factor" of HFC's and the various substitute refrigerants. And some talk of alternatives for the alternatives...
So if this company is referring to R134a, the only way this would be legal, under federal law, is in a closed loop system.
Personally, being as how I have much experience handling refrigerants, I have always pondered common refrigerants replacing butane (although butane is of course, a refrigerant, as R600 is N-butane AKA "normal butane" and it's cousin, R600a isobutane) in this sense. <snip>

Unfortunately they put a 'bitterent' in it discourage huffing...
I think Greenjunky1 may be passby.

They need to have tested,
The percentage of the main gas(es) in the can
The percentage/ppm of impurities in the gas
The percentage/ppm of gas(es) in a samples of cannabis oil (with varying degrees of purge.)
The percentage/ppm of gas impurities in samples of cannabis oil
The percentage/ppm of gas(es) in vaporized samples of cannabis oil (with varying degrees of purge.)
The percentage/ppm of impurities in vaporized samples of cannabis oil
I would suggest they use the testing facility Graywolf found, Specialty Analytical in Portland, Oregon.
