When I lived in Wichita. the 'toke of desperation' was "Kansas City sore-throat" harvested wild from river banks. I had VERY few experiences to judge by... but one party had both 'electric' and 'acoustic' brownies. I had the good stuff before I grokked the difference.

One musician I knew grew his own, called "Benton silo" after the town and the growing situation. It was treated like old brandy by the locals... passed around on special occasions with reverent whispers. I never was offered any. The one and only time I ever partook openly was at the Smithsonian Folk Festival in 1973? I think.... people were passing it up & down the rows, while mounted D.C. cops rode past, ignoring the fragrant clouds.

Medical? I dunno... never needed it myself, but keeping the thread up to the top...
