I've been addicted to cannabis in exactly the same way as I was addicted to alcohol.
I was addicted to escaping reality. Only recovery helped me deal with that.
Pot did nothing for my anxiety in the long run either - if anything it made me more paranoid and frightened.
There are other side effects from pot too.
One of the big ones for me was it made drinking again seem like a good idea: why just be high when you could be high and drunk as well?
It was not a good decision on my part.
