My smoking actually helps my anxiety so Im not sure if I can help but from experience... My anxiety is always lower when Im doing everything else in my life right... ie less stress. maybe take away what youre tripping on when you have attacks. also, I once went to a foreign country were i brought in a small amount of hash. Our only option was to smoke the hash/cigs you were describing. It gave me a raging headache and a panic attack but I dont smoke tobacco so I just chalked it up to the tobacco and not the weed. after all, I have friends that smoke both all day long without recourse. But man i feel for ya...
