I agree that we need more hard data, more science in general and specifically more studies on cannabinoids and their development over time in relation to conversion, oxydation & decarboxylation etc.
However, I do believe that we are seeing an increase in these sorts of studies, but since the nature of scientific studies are very specific, it's hard to get exactly what you want.
And much of the science being done on Cannabis and cannabinoids is rather elementary if you will, not that it's too basic or useless, but we haven't had a free flow of Cannabis research and science for a long time, we still don't in much of the world, and there is a hell of a lot of research to be done on these subjects. Most of what is done is studying the effects of the biology of the receptors and how the human body reacts to specific compounds, not broad studies on the cannabinoids themselves and their development.
I found a really nice study on the difference between vaporizers, including one I own, which is how I found it, and I must say that it's nice to see studies on cannabis, cannabis products, cannabinoids and tools are becoming much more respected and prevalent in the scientific community.
The study I found on vaporizers and how efficient they are;

With regards to your question, I think there are a lot of institutions and organizations who carry out great objective research, but if you are looking for hard science the best place to look is in
scientific journals.
Much of the research being done is very specific though, and you'll have to spend a long time researching all the different studies to find something that resembles the holy grail of the study you are after, which I presume to be something like; "In vitro & in vivo quantitative analysis and validation of cannabinoid development and conversion in Cannabis".
A study like that does not really exist at this moment, hopefully it will in the future.
