One hears the tales of drugs so tricky that it only takes a single exposure and blammo! You're hooked for life.
I wouldn't know. Smoking cigarettes took me almost as much effort to start as it did fifteen years later to stop and I had the advantages(?) of youth, incipient juvenile delinquency and having grown up around smokers.
The effect of any such drug is as nothing, a sigh in a windstorm, compared to impact of the wondrous world Terry Pratchett has created!
It took about six pages into one (1) book (Going Postal) and I was aitch-oh-oh-kay-ee-dee addicted.
If you haven't read any of the Discworld books, you've missed one of the finer treats. Cross Cyril Kornbluth's take on fantasy with Heinlein's politics and toss in a generous spoonful of "Monty Python" and "Red Dwarf" and you're starting to approximate it. What I've read so far (One Entire Book, With Blurbs) would have been right at home in the long-gone and much-missed fantasy mag Unknown but would have outshone anything ever printed in it, up to and perhaps including "Magic, Inc."*
My thanks to the many friends who recommended this author!
* A citation from memory that took fifteen minutes to verify, including an enjoyable digression into a magazine article about RAH's self-designed home in Colorado Springs. Alas, I've yet to see one as complete about his circular house in Bonny Doon, CA, which is instantly familiar as a smaller version of Jubal Harshaw's home in Stranger In A Strange Land.
