How many states where hammer is not thrown in high school?

In the United States, hammer throw is not commonly contested in high school Track and Field events. As of my last knowledge update, only a few states, including New York and California, allow the hammer throw at the high school level. The majority of states do not include it in their high school athletics programs, often due to safety concerns and facility limitations. Therefore, the number of states where the hammer is not thrown in high school is quite high, likely exceeding 40 states.
