i was on probation three years ago.  they tested me for pot and coke a lot, but that was not all.  also morphine/herion, which may or may not be the same test, speed/barbituates and methadone.  a safe thing to remember is you need 72 hours for everything to disappear out of your urine (except pot, which stores in your fat cells and slowly releases into the urine for up to thirty days).  NO EXCEPTION, IT DOESNT MATTER THE AMOUNT YOU TAKE,,YOU MUST HAVE THE SEVENTY TWO HOURS OR IT WILL SHOW.  And the person who told you about the cost for the test, this is true, if your applying for a job.  this is probation, they have the sticks individually wrapped for each and every drug that can be abused.   they dont care about over the counter. everything else better be backed up by a RECENT doctors perscription or you need seventy two hours to get clean,  ANYTHING ELSE BUT WHAT I JUST EXPLAINED WILL BE A VIOLATION OF PROBATION,,,,,BACK TO JAIL
