I would warn against asking this. This is a question you can not legally ask in this manor. You can instead advise that the job requires him/her to work certain hours and that missing work/leaving early would result in discipline action up to and including termination. You cant ask this one and by doing so you are opening yourself up to law suit as well as fines from the state. You can can list the job duties and requirements such as standing all day, constantly lifting /carrying 75lbs, etc.. But you can not ask about specific injuries You also can not ask specifically "do you use drugs?", what you can do is ask on the application "can you pass a routine drug test?", and state that you test all applicants for illegal drug use. Even if you don't plan to test them, putting this on the application will weed out potential problems.
