Was Tolkien good at blowing smoke rings? Could he blow any other shapes? Could he blow rings through rings? Did he ever smoke marijuana? What quotes of his indicate that he wrote about a real time/place? Did he assotiate with any mystics?
I'm unsure what tricks JRR could do with smoke rings, but it is unlikely he smoked marijuana. I have read somewhere that he was quite anti-drugs use. There is an old thread somewhere in this section that discusses this topic.
