How long does marijuana stay in your system?

My friend wants to know. She NEVER smokes, but about one month ago, she took part in a bowl or two. The crappy part is she just got a job offer, and they want her to take a drug test.

She's lost a lot of weight since January, drinks a lot of water and works out almost every day. I've heard these things can help minimize the THC in your system? Also, when employers drug test, how do they usually do it (urine, blood, hair?) Hair would not be good.

I guess the main concern is how employers typically drug test. If it's the urine, I don't think she'll have a problem. But the hair or blood would not be good news (she was somewhat of a wild child in college). Any input?

After one month the urine test should test clean. But it stays in hair until it grows out! Employers usually opt for the urine test as the immediate past is more important than what she did or did not do some time ago:) Dont worry!!!
