The federal government (Department of Transportation) and most states feel that any level over 15 ng./ml is considered a failed test and, as such, is presumptive and likely to hinder judgment, and a presumptive cause of any injury or accident.  Obviously a level of 559.0 is a quite bit higher than 15.0  In general, a level of 559.0 is a very, very high level and indicates that this individual has been using marijuana for a very long time.
