The same happens to me, but the next day I feel a significant decrease in anxiety. I wonder if the pro-anxiety effects of THC are overcome by the anti-anxiety effects of CBD over time (e.g. the anxiety effects of THC last for a few hours, the milder anti-anxiety effects of CBD last for a couple of days).

FWIW, I have the opposite reaction to different strains. Sativa gives me anxiety, while indica makes me want to relax and take a nap. Really hope researchers can start testing effects so we can figure out where this can help anxiety. So many people I know struggle with it; I'd love for them to have a way to treat it.
