What does the federal and state laws say about drug screening public students?

[chika]

in my state students have to submit to drug testing when they register for class's and any extra cirricular activities. also if they are driving their cars to school. and they also do "random" testing on any one dumb enough to submit to one

The courts have upheld school programs randomly drug testing high school athletes, Veronia Schools v. Acton, 115 S.Ct. 2386.
However, a program testing all students may be tougher for a court to swallow.

The lack of voluntary action to expose oneself to the possibility of a drug test likely violates privacy rights, Anderson Community School Corp. v. Willis, 158 F.3d 415. For extracurriculars, students voluntarily chose to play sports, which the court used to justify the testing. Here, there is no choice.
