The Daily Beast has a breezy new piece by Anneli Rufus, surveying recent “scientific studies” on pot, some pro-, some con-.   What’s remarkable is that this piece was published at all, with such flair and cheerful skepticism. Does it signify an Awakening, at long last, of the media to the BS that sustains prohibition, now that the readers, listeners and viewers are starting to get it? Brava to editor Tina Brown, who leads the edge of everything she touches.
