Marvin Nicholson, my ever-obliging trip director, has marked a copy of the Wapo for my information. It describes an innovation in the marijuana market that involves dissolving cannabis oil in butane. The brittle result is apparently called "shatter" because of its propensity for doing so. I wrote "please obtain sample ASAP" in the margin. I knew that Miraculous Marv would come through with some, and promptly. Yum!
