To anyone who's confused by the title: the law was passed in November (by ballot referendum), but it went into effect today, with the first recreational sales. (Medical marijuana was already legal in Nevada). By contrast, Massachusetts also legalized marijuana on the very same day - and by an almost identical vote margin - but Bay State legislators are still contemplating whether to let the law take effect at all, and it's unclear if and when recreational sales will actually become legal.
