It is truely amazing the diversity of things cannabis produces. Especially terpenes. The variety is staggering, despite being cultivated almost exclusively under prohibition for the last 50-100 years.
Now when I see “oil of oregano” I think, “well, I wonder what oregano cultivar they use” or “what was the farming method” or mental debate about the extraction method. 
Just go buy a bottle of Everclear and give it a go. Or whatever you have access to up there. You can also buy food-grade ethanol not “intended for consumption” I believe. It’s not dirt cheap here either, maybe just get a small container if you can. I only used ~200mL of my 750mL bottle. If you have kief you won’t need as much as washing buds, that was abundantly clear. I’m sure I could have used only 100mL of ETOH to dissolve my 10g of kief. I was intimidated too, but it was pretty straight forward. The candy was easy too, just followed @ReikoX’s instructions to the letter.
The difference between doing and wanting to do, is the doing part. I’ve been learning to just go do things. Sure, I spend a bit of time reading, then decide I’m just gonna go give it a shot. Otherwise I’d just read all day and accomplish little. I’d rather do these days. Maybe it’s age. All gas, no brakes. If you put weed in alcohol, it’ll work. 
As far as tissue testing goes, I spent some time looking into it but haven’t followed through. It’s kinda like the soil testing, a little nebulous as to who actually uses who for cannabis testing. Maybe it doesn’t matter and I just send to one of the university extension offices that pops up when I google.
I hadn’t even see those sketches but I would have used some of those lines
Cheers man!
