Timeshift reveals the story of the creature that is 'the smoker'. How did this species arrive on our shores? Why did it become so sexy - and so dominant in our lives? Was there really a time when everywhere people could be found shrouded in a thick blue cloud? Enlisting the help of Barry Cryer, Stuart Maconie and others, The Smoking Years tells the unnatural history of a quite remarkable - and now threatened - creature. Warning: smoke-filled nostalgia may damage your health.
