1. Should employers be permitted to mandate tobacco-free workplaces, and to require employees to undergo pre-hire drug screenings and random periodic testing as a condition of employment? What are the legal concerns here? 2. If an employer can demonstrate objective correlations between health markers (such as cholesterol, blood pressure, BMI, etc.) and insurance costs, should they be permitted to create policies that require new employees to undergo physical assessments and meet certain standards as a condition of employment. Could this be done short of requiring a "medical examination"?
