i tend to think that smoking helps calm me out. i have bi-polar and real bad anxiety and smoking tends to calm me out. it helps a lot with the bi-polar cause it keeps me calm and keeps me from cycling from depression to mania so often or as badly cause i am a rapid cycler. with the anxiety it just calms you down enough to not worry anymore. i am on meds which work overall but smoking helps in the times when it starts to get real bad or something and you just need some extra help.
