There is a big difference in opening it up and dumping it in a tank, and blasting it against a metal surface at high speeds. Once again, totally common sand would have negative effects.
I bet if you took fluval shrimp stratum or many other substrates, blasted it against metal at a high rate of speed you'd get some of the same results. A decent dose of caution is good, too much and we're left with bare bottom tanks, with no decorations because we're afraid.
You shouldn't take life to seriously. You'll never get out alive.
