I’m not a marijuana expert either, I don’t smoke it myself, though I think prohibition is stupid. I’m a chemist. My knowledge of this is based around stuff I’ve read about it (cannabis is a popular topic in the secondary literature) and based on my knowledge of organic chemistry and natural products.
That’s not really about creating intermediaries. At crockpot temps with butter and oil, you’re preforming extraction, pulling the hydrophobic plant oils and residues into solution. There are likely side reactions like Maillard reactions and what have you, but it’s impossible to guess all possible outcomes from general principles.
Not knowing anything about how these businesses are run, I don’t trust these numbers. I work with natural products at a soap company, and I’m can’t really share why, but let’s just say I wouldn’t be surprised if analytical tests showed these numbers to be off. I’m very curious to know what kind of regulation exists for these numbers. The testing is expensive (and you need to test to get these numbers) and I can absolute see people cheaping out here.
Like I said, I don’t know that the numbers are bad. I am happy to be presented with more information. My ego is not invested in my hunch, but as I said the hunch is based on related experiences.
