I have heard alot about them breeding strains where the THC is low and the CBD is high. This seemed to be for seizures though.
I don't know which cannabanoid is better for anxiety thc or cbd.

From my experience there is a sedating type and a kind of make you more paranoid type. It seemed to me they were both very high in thc. The high THC is not a bad thing you just limit your dose. Only take a couple of hits. I have friends who still smoke and they take two hits and wait and see how strong it is before smoking any more. I am not an expert though and have been out of the game for a very long time other than my little experiment for depression. If you ask in the dispensary they should be very well versed in the types and the effects they cause.

You may be after the psychoactive effects of the THC to relieve the anxiety. I am not sure.
