Alcohol and tobacco are legal, and, according to our analysis in Chapter One [Addiction Rates], are used much more frequently than illegal drugs. Because their use is greater, the amount of damage they cause will also be greater. But this is not to say that one "dose" of alcohol is inherently more dangerous than one "dose" of cocaine. As James Q. Wilson explains, predictions about the harms of cocaine that assume its illegality tells us little about what damage cocaine would do if it were legal.
