A trio of teens may be charged after they allegedly gave 23 fellow band campers pot brownies—without telling anyone the treats were laced, the St. Louis Post-Dispatch reports. No ill effects were reported, but “we won't let this slide," says a police sergeant. "It could have been a very big deal." Police found out about the prank when one of the suspects told a fellow student, who told the school. “It could have been an interesting band practice,” says the officer.
