If you do then you may void your warranty if it's a Mac.
Mac denies warranty coverage to smokers computers
Quote:
Specifically, in at least two instances in different parts of the country, Apple has voided the warranty and refused to provide repair service on Macintosh computers exposed to environments where cigarette smoke has been present. Calling cigarette smoke residue (tar and whatnot) inside a computer a health risk and a "biohazard," in both cases Apple customers have been denied service despite having time left on a valid warranty.
