This book destroys the myth that illegal drugs have some magical power to transform a user into a drug crazed addict almost at once. Certainly there are people who are more likely to become addicted to various substances, whether it is alcohol, marijuana, heroin or even gambling. But for the great majority of people it is clear that limited recreational use is possible. Given this, the war on drugs is an absurdity. And one that is costing more in money and human suffering than can be imagined.Saying Yes is the best book on drugs use and the drug wars since Mike Gray's (1998) Drug Crazy.
