"The percent THC is the weight for weight of THC in the dry cannabis sample selected for analysis. A fresh cannabis plant contains a lower proportion
of THC as fresh plant material contains a lot of water." <---- This is the info you should pay attention too from the reply to the question! (notice home office is a bit more mature in their response than STONEDMETALHEAD1 calling names.... tisk tisk
"With alcohol, strength is measured in percent alcohol by volume (%ABV), but clearly the THC in cannabis doesn't amount to 10% of the volume nor of the weight, so what is it a percentage of?" <--- This is the question asked by someone wishing to decrease the areas of their ignorance on the subject we are all discussing. Don't focus on this as a reason to back your belief.
A GC (Gas Chromotography) test does just that! Test the gas that comes of the burned cannabis sample submitted for testing. ( they try to dry it out fully before the test for best results) Look at the e.g. they gave ----> "THC when cannabis is heated (e.g. in a cigarette)"
You are both kinda right = Stonedmetalhead1 it is not % of weight , but it is the "weight for weight!" It is the % of gas of the entire "sample selected for analysis!" <--- That's why hash has a higher %! You "refined" (as you put it) the majority of leaf, flower, and other material right out of the sample that will be turned to gas in a GC test!
No GC test is 100% accurate! All be it a small margin, you can test samples from the same plant multiple times and have multiple results. A more scientific test would be an HPLC (High Performance Liquid Chromatography) and IMHO also include a GC test after.
MY POINT = This will give you the liquid compound result prior to the gas compound results! This is important because of the increasing market for edibles and other forms that are never turned to gas!!! Also some compounds like THCVA are turned to THC when turned to gas form... This is important to me because I want to know WHICH STRAIN HAS THE HIGHEST % OF THCV!!! This is the compound know to cause a psychedelic experience!!!!!! (in case your still looking for the reason we used to smoke it before glaucoma, anorexia, and etc...
This I hope ties it back to the original purpose of this discussion what strain has the highest amount of THC? (IMHO - I think this was worded incorrectly by hazey grapes for the purpose of the question) Give your money to the guys with the 20%+ test results, because they will get you where you want to go and maybe your mind will convince you to brag to your buddies that it's the most potent stuff around....
QUESTION TO THE EXPERIENCE CANNABIS CONNOISSEURS OUT THERE = FORGET ABOUT THE TASTE, LOOK, AND SMELL FOR A MOMENT AND TELL ME "WHICH STRAIN GOT YOU REALLY FUCKED UP?!?!?!" (and NO bigguy.... I'm not 14, I do support the medical side of the cause, but I refuse to feel shame for just wanting to use it recreationally like all the guys who go for a drink or smoke cigarets)
ALSO A QUESTION TO THE SCIENTIST (if any are out there) = "WHICH STRAIN HAS THE HIGHEST THCV%?!?!?"
I probably should have started another thread with these questions, but this one seems to still be pretty active. Also, most people would word the question for the answer I'm looking for like hazey grapes did.
Hopefully this can stay an spirited/intelligent/positive discussion amongst a people of a united cause, and we leave the spiteful/ignorant/negative debating to the politicians impossible to unite egoistic agendas
