If a person was fired for a positive drug test can that employer disclose to potential employers what drug they tested positive for?

yes your employer has every right to terminate you fer testing positive on drug tests.

well if you eat a large amount of poppy seeds you can come up positive for drugs...also if your around people who smoke herb...it can show up in your system.. well if you eat a large amount of poppy...

There's no set period of time, and the employer doesn't even HAVE to terminate you if he doesn't want to.

no

yes if you have proplems with drugs your employer has to pay for rehab
