"TAKE your best orgasm, multiply it by a thousand and you're still nowhere near it." That's how Irvine Welsh's character Renton describes the pleasure of heroin, and the words ricochet from Trainspotting, the book, through John Hodge's film script, and now through Harry Gibson's adaptation of the work for the stage.

To bring on the old alienation effect, a radical, experimental approach to Trainspotting would have to have been taken; to create a simply tragic effect, a carefully made tragic structure would have to have been welded together.

Instead the excellent actors dig through toilet bowls, mainline, find a dead baby, and their rich Scottish dialect is laughed at throughout.
