Multifamily housing typically doesn't consist of hermetically sealed units. If your neighbors are doing something that produces odor, if it's strong enough, others are going to smell it in their units too. Additionally, shared spaces in the building often ending up smelling too. This isn't limited to pot smoking but it is a common enough occurrence that it's unreasonable to mock someone for mentioning it.
