I watched the first ‘Hobbit’ movie on TV last evening. Written by the author of ‘Lord of the Rings’; JRR Tolkien. One of the main characters, Galdalf the Wizard is often seen smoking ‘Pipe Weed’. I have heard that is obviously not Tobacco.
In the movie; Gandalf shares a pipe of it, with another Wizard & his eyes open wide & a large smile comes upon his face. The author was likely to have known of cannabis, which was probably still legal in his youth.
I have also heard that many famous authors of the late 19th & early 20th centuries likely gained ‘inspiration’ from such intoxicants. I’ll leave it to you to decide… 🙂
