CBD itself shouldn’t cause anxiety, however CBD oils can vary a lot in terms of the cannabinoids they contain.

Full spectrum oils can contain very small amounts of THC, although not enough that it becomes psychoactive for the majority of people. However, it is possible that people with an acute sensitivity to THC might start to feel some effects.

Broad spectrum oils specifically contain 0% THC, so those are the ones to go for if you want to rule out the possibility of reacting to any THC in the oil.
