I posted this in another "cig and neuropathy" post

My wife has taken a "drag or 2" from our daughters cigs (she's 22), and it DOES NOT help her (at least). Can't speak for anybody else.

Cyclops is right in saying that addictive things are addictive for a reason. No matter what, cigs can cause your neuropathy to get worse.
My wifes docter told her straight as can be.."If you continue smoking, even a little here and there, you WILL lose your legs. Smoking is one of the major causes, or at least speeds up the damage to limbs, for people with diabetes and neuropathy"....this scared my wife into quitting finally.

We have been smoke free for a couple of years now and feel much better health wise also since quitting.

I wouldn't even attempt using cigs for pain control, whether it works or not....

JMO:
Any foreign matter put into the body is going to cause some damage sooner or later.
Cigs contain cyanide...this can do serious damage to a body over long time usage, especially to an already weakened body from diabetes.
