Well, I was smoking some CBD bud and some 50/50 strains, but they are hard to even get seeds for.... Unfortunately the entire American cannabis industry revolves around insanely strong weed.... I wish I could go back in time and tell myself to never touch that stuff and only use low THC strains that have more balanced cannabinoid ratios, even if it meant growing only one or two strains that didn't yield as well. It is absolutely related to the super high THC levels, I mean people in other countries outside the US and Canada also get CHS, but it seems much much less common, and I don't think anyone was getting it before the 1990s here.
