I've just finished reading High Society by Ben Elton. It is a novel exploring the full legalisation of drugs from differing points of view.
It isn't a laugh-out-loud novel like Popcorn was, but you remain interested in the characters development throughout the book. As with his previous work it is immensely topical and is a positive addition to the debate. I found it an entertaining read and it certainly made me think about what is politically a taboo subject.
