People like Chubbs and the crew at Nuggetry that are super knowledgeable about genetics and do strain reviews. I don't get how they're so precise about the buzz type. Maybe I'm just smoking the wrong bud, but besides the super obvious difference between an Indica and Sativa buzz, there's not a whole lot of variation in what I feel when I'm high. I get scientifically how different THC to CBD/CBN ratios can affect the high, but rarely are my highs vastly different or something I could elaborate on beyond the "head/body high". I thought maybe I was just smoking too much bud, but they smoke just as much as I do if not more, so there's that.
Its like a food critic describing tastes and textures and the essences of the food. They are passionate about it and savor the details
you just have to try to remember what tha buzz type was like after you wake up from your food coma, or once you finish your 6 hour mtn bike ride....
I think that's it. I get pretty good bud, but the half dozen or so times I've gotten to smoke a Top Shelf dispensary quality strain I've been floored. I even wrote a very descriptive review on Nuggetry of one particular strain.
I do that with everything but the buzz. I want the smell of Trainwreck as a cologne, and dense, sticky boulders of Master or OG get me as excited as Christmas did when I was a kid. But unfortunately my market sucks and I don't have access to the super danks on a very regular basis. I think I could become more familiar with different buzzes if I had access to tons of different and specific strains like Shane or Toph.
It helps alot to distinguish different strains if you have a constant supply to high grade and are the real strain. If you just pick up no name of course it's going to be really hard to differentiate because you never get to set a baseline on what's what. They get to smoke bud that's measured how much indica/sativa and thc content etc.
