Drugs, whether legal or illegal simply mask symptoms. They can never deal with root causes. I myself smoked weed for 7 years daily and I wound up with panic attacks and the start of 2.5 years of anxiety etc. Everyone is different when it comes to cannabis tolerance. But it won't cure you of anxiety.

Anxiety needs to be tackled in a sober state of mind via acceptance of anxiety, understanding anxiety and removing the fear and worry that fuels anxiety.
