There seems to be a better understanding that CBD is favorable and a growing understanding of the other cannibinoids. I wouldn't be surprised if the greatest risk for bad selective over-breeding for THC content would have more been during the illegal periods with less legal science available and a lot more concentration of breeding among fewer breeders with unbalanced incentives of an illegal market.
A legal market is, in theory at least, going to have much more opportunities to do science out in the open, more opportunities to track breeding experiments and not just over-select one direction or another, more available research not just on the one notable desirable ingredient, but the larger ecology of them.
