I have called police on my daughter...and at this stage of the addiction...wouldn't hesitate.....and I think above advice is good...if you insist she go to rehab...she can leave...but if the court mandates it...no choice.......
I know how hard it is....you don't want to affect their future....tough call !!!!
But if you don't do this....perhaps things will get worse.....there are supposed to be consequences right?
