It has been my experience that most people's body will process marijuana in such a manner that it will not remain in their system for more than 30 days. After 60 days, there should be no trace of marijuana in your system. Perhaps there's a problem with their test kits. You have a right to have your own independent test performed by a lab. You might want to have a blood test done, as it's more accurate. The cost of these tests is minimal incomparison to the cost of a possible 2nd violation of probation and where that may leave you.
