Is there anything else I need to know about a drug test?
If you test positive for a legal drug prescribed by your doctor, your employer can’t penalize you for a positive result, unless the drug is affecting your ability to perform your job.
If you test positive for marijuana and live in state where it has been legalized, employers may be able penalize you. Many employers want to maintain a drug-free workplace. Also, marijuana is still illegal under federal law.
