Was thinking the same thing as Clock26-- It may not be that earlier first drink predisposes one to alcoholism, but that predisposition to alcoholism leads one to start drinking earlier, or a third variable (such as parental behavior) causes both early consumption and later alcoholism and thus creating the correlation between the two (one which is not causal).
