anecdotal, but i am certainly an individual with adhd and i personally find strains marketed as indica dominant to be far more effective for anxiety relief and just general functionality. it also may just be a random correlation, but i always recalled seeing higher levels of cbd in indica based strains when I lived in Washington and the actual levels of cbd and thc in the product was listed on the packaging. i certainly don't think this is strong evidence that such a thing is the case, in an overarching empirical sense, but i can at least say, with confidence, that for me, indica dominant is much less anxiety inducing
