Uh, no...5 months is a long time!! Weed stays in your system for only 2 weeks...and crack for about 72 hours, if doing a urine test. A hair test can go as far back as 90 days (three months). If you've been clean for 5 months...you are fine.

Yes it can. Hair samples are the most effient way to test for anything. Even if you flush your system it will still stay in your hair. They can find out what and when you used it.
