Gary Winship 
Addictive Personalities and Why People Take Drugs [PDF ebook] 
The Spike and the Moon

‘Why do we take drugs? I haven’t the faintest idea, but Gary Winship has a damned good go at telling me the answer. Some might say this is a largely academic book, but as an ex-psychiatric nurse and a Jo Public for the last twenty-five years, I’d say there’s something in here for everyone. We’ve all taken drugs at some point in our lives (except, perhaps, my grandma) so one way to find out why is by reading this fascinating book.’- Jo Brand, comic, author, and actress
