My husband was sentenced to five years probabtion. I've never been through this before so I'm cluless. I know the first year is interim probation does anyone know how often you have to go check in with your PO and if you have to pay out of pocket for the manditory drug test. Niether of us do drugs of any kind so I'm not worried about him passing it I'm worried about how much it's going to cost me when they do it.
