That to stop smoking could cause/create more stress than not doing so...
I happen to smoke...I state it flatly and without reservation - with the qualifiaction: That to quit smoking now could probably do more damage to my overall systems more than not smoking.
Besides It's the ONLY Vice I've left these days?
Honestly, in all my 'researches'...I have not seen one definitive connection between smoking and PN...other than potential vasucular aspects of which I at least have been vetted clean.
Soo, If I start to read DON't SMOKE posts here...I am gonna block them. Sure beats grinding the teeth!?

Honestly Melody, There ARE NO DOCUENTABLE correlations!!!!!!!!!!
All alleged science to date implies: If the horse has stripes, it MUST be a Zebra! Many other equine species have a stripe.

Other than implications of vascular constriction...nada -zero -zip zilch!

Mark - as you can gather, we are a community, with differing opinions about things...well, I guess you got to see one of my barrells...But, I seem to have a knack for finding particulars on various key medical issues...
If you read prior posts you will be able to get a 'take' on us who do vs. don't.
Keep heart and think clearly - that will get YOU thru! - j
