And there was a liquor store about 900 feet from my high school. And a bowling alley next to it with a bar inside!
Having a dispensary near a school is in violation of Title IV the Federal Safe Schools Act of 1994 and various state laws that are linked here

I do take back Title IV because there is nothing mentioned there. However, there are states that have the 1000 feet rule. California does have that rule.
