Smoking

[AgentX]

I had a 2100 graft hair transplant on Oct 3. I quit smoking two weeks prior to the surgery, and didn't have any cigarettes until exactly two weeks and one day after the surgery. Since the surgery, I haven't fully picked back up smoking. I've mostly just had a cigarette here and there. Never more than 3-4 cigs in one day, but I go most days without smoking at all.

I was just wondering if I'm in great danger of completely ruining my results? Am I screwed?

And one other important question I'd like to get answered is how soon after one cigarette do your blood vessels return to their normal state. In other words, how long do the negative effects of one cig on your blood supply last before they wear off? I mean, does one cigarette completely ruin you for months? Or does the negative effect go away within hours/days?
