Drug info - how long does heroin stay in your system

[gardee]

Swim has a drug test coming up on march the 16th and is wondering if he uses on the 12th will he be able to pass if he he doesnt use again after the 12th? Swim will also be running for at least 20 minutes a day as well as taking hydroxycut on each of the days from the 12th to the 16th. But Swim will not be shooting the dope until at least 11pm on the 12th and his probation appointment is at 11am on the 16th. Please let Swim know asap if he is in the clear for his drug test or if he needs to go another route to make sure he will pass the test, a route other than not using. It is a probation test by the state if that makes any difference at all for the answers swim gets from whoever may answer this question....Thanks
