Is it safe to use an e-cigarette/vaporizer after Lasik surgery?

I had Lasik surgery 3 days ago and want to know if there would be any side effects on using an e-cigarette/vaporizer? When would it be safe to do so? Also, if harmful, would it be the vapor itself getting into the eyes or the effects of the chemicals being inhaled and if either would have any effects on the healing of the eyes?
