“Dear Residents,
“… We are notifying all residents on your floor of a series of complaints we have received regarding an unusual odor. At this time we are unable to identify which apartment the odor is coming from and, as a result, feel it is important to heighten everyone’s awareness to bring about improvement.
“A smoke odor has been detected that is not related to cigarette, cigar, or cooking smoke. The odor is creating concern that perhaps an illegal substance is being smoked in an apartment.”
