If it's any consolation to you, I'm a moderator on a cannabis forum and I can't smoke. I not only agreed not to use illicit substances when I entered medical school last year, I also have some serious heart-rhythm and pulmonary health issues that cannabis wreaks havoc on. I had a 7 1/2 hour minimally invasive surgical procedure a week ago to fix the heart rhythm problem and am having further complications since then. You at least will be able to go back to smoking sometime in the future. I'm not sure I ever will.

I feel your pain. Keep in mind that, in your case, it's not forever.
