Worst case scenario I would have 3 convictions of a class 4 possession of a controlled substance. I've been clean for over a year now, have gotten my life together and understand that I have to complete probation as court ordered. Now my question is, once i've successfully completed my probation, is it possible to get all 3 of these cases expunged or sealed? And if not, is it possible to become a lawyer or DEA agent with a record like mine? Thank you!
