“The goal of the smoke-free policy and procedures is not to evict individuals and families,” said PHA’s President and CEO Kelvin A. Jeremiah. “It is actually to provide additional support for cessation, to identify smoking as a real risk to health and safety. Managers and other employees will not be serving as the smoking police.”
