Note to Nick S. and Jonathan B.: That book I was advising you to get —Cannabis Evolution and Ethnobotany by Rob Clarke and Mark Merlin— has been added to the “recommended reading” slider in our Column Three. Better order a copy fast. Amazon has only 13 available, which may be because UC Press underestimated demand.
We’re also posting the review Dr. Ethan Russo wrote for HerbalGram. Russo notes that the authors “concentrated on different origins for morphological variants of cannabis named Putative Ancestor, Narrow-Leaf Hemp, Narrow-Leaf Drug, Broad-Leaf Hemp, and Broad-Leaf Drug, based on chemotaxonomy…” But don’t worry, we’ll always have Sativa.
