Can I smoke, nicotine free e-cigarette after a FUE? (Photo)

I know that smoking is bad after FUE, for many reasons but especially for the blood vessels that help the healing process and for the new hairs to "accept their new himes" but I can't sleep more than 2 hours a day right now and the urge to smoke us too great. We're on day 3 and so far I've had 6 cigarettes already. Would it help or be less detrimental if I used a nicotine free e-cigarette. Please help. Thanks P.S. So far there's no bleeding but it does itch. Here's a pic of my grafted area.
