For starters, everyone’s goals for cannabis use are different. A person with Crohn’s for example, who uses cannabis for nausea relief will surely have a different ideal ratio of THC:CBD than a weekend warrior who uses it for muscle pain. There’s no one dosage or ratio that works for everyone and I think that you are greatly exaggerating the importance of weed's so-called "entourage effect" re: THC, THCA, CBD...prolly some terpenes floatin' around in there. I dunno...
Besides, pursuing greater THC "heights" and in process, pushing out CBD has been the way for decades. This is nothing new and those "80% of strains" you sneer at are borne of the same methodology as previous efforts before commercial outfits perfected it.
What's more, "CBD heavy" strains with only 0.3% THC are wildly in demand these days. The more "balanced" iterations with up to ~20-25% THC & ~6-12% CBD are also gaining in popularity.
As a recovered addict who has spent many months in multiple rehabs and many hours at meetings -- with hundreds of other addicts, I can assure you that booze is EASILY more dangerous/unhealthy/addictive than weed. Across the board; worse by every general measure.
