I started to see some super high T.H.C levels( btw. 21% to up too 28% ) and I started to doubt these tests. A few months ago I saw an article in a local mmj mag. talking about testing and so I checked it out. They took a strain and took 3 samples from the same plant to the diff. Testing centers to compare the results. Full spectrum tested at 29% thc and the lowest levels where around ten percent less thc than the leader. Each company uses diff. Testing equipment and methods so that can explain the results, but it leaves a lot of doubt in my mind. We need to find the most accurate testing method and stick to that proven method to give it some sort of level playing field to test from! I have found that some strains I smoked did not test over 20% but got me way higher that a similar type strain( indica, sativa,etc..) that tested at 28% thc and they had similar cannabanoid content(cbd,cbn,thc-v). I think the science is on the right track, but still missing something! I would try herbal synergy out of Colorado to do a test. I think they tend to be a little more accurate!
That method would be HPLC. Everyone else using GC is using a destructive analysis. HPLC is nowhere near as destructive and thus the results are far superior.
