According to the statement, half the rate of 40 years ago means 50% of the previous rate. Since the question does not provide the previous rate, we cannot calculate the exact percentage of current smokers. However, we can estimate that 18% is the closest option to half of the previous rate. Therefore, the best choice is B.
