Anxiety causes smoking

It's not just in my head that quitting smoking is super hard for me. Oh wait, it is in my head:

"...participants with anxiety diagnoses were much less likely to quit smoking.

Study results also showed that anxiety diagnoses were very common among participants -- more than a third of them met criteria for at least one anxiety diagnosis in their lifetime."

I think I've talked about my panic attacks and anxiety before. It apparently makes it harder to quit, and in the study even a combination of the patch and the lozenge didn't make people quit. Fascinating. I wonder when I'll be able to do it?
