Farewell Bend Park in Bend, Oregon
The Bulletin, a newspaper based in Bend, Oregon, runs an article, "Tokin' about books: reading and writing under the influence," by David Jasper that mentions RAW. After interviewing a local reader named Karie Alexander who likes to read while she's stoned, Jasper lists a number of "Stoned Authors," including this one: "Author Robert Anton Wilson began using marijuana around 1950, and in the 1960s tried mescaline eventually becoming a counter-culture favorite with books such as the "Cosmic Trigger" series and his friendship with Timothy Leary."
I should probably clarify that marijuana use and possession in Oregon has been legal since July 1, 2015, thanks to passage of a state question in 2014. About Ms. Alexander, Jasper writes, "Alexander likes to take a toke or two in the morning before heading to a coffee shop near here east Bend home, where she has a bagel and reads for an hour every morning. That's been a tradition for her for 20 years, Alexander said."
Paul Krassner once wrote that Wilson "became a dedicated pot-head in 1955." Krassner also wrote, about Wilson's writing process, that all of Wilson's books were "written with the aid of that good old creative fuel, marijuana. He once told me about his creative process: 'It’s rather obsessive-compulsive, I think. I write the first draft straight, then rewrite stoned, then rewrite straight again, then rewrite stoned again, and so on, until I’m absolutely delighted with every sentence, or irate editors start reminding me about deadlines — whichever comes first'.”
I don't know how to survey this, but I have to assume that some of RAW's readers have been known to consume marijuana before reading his work.
Hat tip, Nick Helweg-Larsen, who can't read the article because something called "General Data Protection Regulation" keeps the minds of the British public from being polluted by articles published in Oregon newspapers.
