Home smoking restrictions were defined by responses to the question: “how is cigarette smoking handled in your home?” with response options being a total ban (“no one is allowed to smoke in my home”), some restrictions (“only special guests are allowed to smoke in my home” or “people are allowed to smoke only in certain areas in my home”), and no restrictions (“people are allowed to smoke anywhere in my home”). Two measures of school smoking restrictions were constructed from questions which asked about whether there was a ban on smoking at their school and, if so, how many students obeyed the rule. These included whether a ban existed (school ban or no school ban) and whether a school ban was strong (most or all students comply) or weak (a ban exists but few or no students comply, or no ban).
