did they actually put in writing that they suspended you for suspicion of selling drugs on the job? if so, you have one hell of a lawsuit against them unless of course they have proof. if they did, im sure they would have called the police by now so.... call them on it. ask them what proof they have and ask them how interested they are in a civil lawsuit. it seems to me they are taking advantage of your age and you naivety about your rights as an employee. i totally agree with those that say stand up to them. emphatically do not let them get away with this, unless you know they have proof. then let it be... and dont be so stupid with your next job.. yeah i said you were stupid to do that. you need to understand you have to be descrete. they take drug dealers a hell of alot more serious than they do casual smokers/users.

good luck
