all that i know is that i had more anxiety attacks while i was smoking rather than now that i have quit. I think i have 1 or 2 a year after quitting smoking. and i have read that ciggs can make you more anxious. it is a stimulant like coffee and after having a near heart-attack-feeling anxiety attack i was told by doctors to reduce my caffeine intake to near nothing and quit smoking. both coffee and ciggs together are 2 bad stimulants to those with panic/anxiety disorders.
