This story is of a different parallel dimension, though it's much like ours. The technical advances are of a more biological nature and the plant life looks the same but has much different and more friendly properties for the humans that live there. In this one, only some of the females even smoke at all. It's not even hazardous for them... in fact it's loaded with beneficial natural hormonal stuff! Only the wise elder women even know of the benefits of it. Such stuff when smoked makes men ill in the mornings for days... naturally, for the first week or so at least... and they leave it well enough alone, though only such women and doctors... know the why of it.
