Yes, but you see, I was charged for the possession of drug and now I no longer get student aid. What can I do?
In that case you can regain eligibility early by successfully completing an approved drug rehabilitation program or by passing two unannounced drug tests administered by an approved drug rehabilitation program.
Where can I attain more information on the criteria for completing an approved drug rehabilitation program?
