I don't know what's more ludicrous -- Illinois law or the comments of some of these posters.
The kid brought a substance to school and claimed to his friends it was cocaine. The conversation was overheard by a custodian and reported. By law the principal must report this situation as he cannot make a determination of drug/non-drug.
The kid's mouth got him in trouble. Next time, if he brings sugar for an experiment, then he shouldn't claim it is cocaine.
The last time I checked at my neighborhood Safeway, powdered sugar is clearly labeled as powdered sugar without a side label saying "but, maybe it's cocaine? hee hee hee"
