If you were not a resident of the unit that was raided resulting in a drug charge against you, you have a good defense to the charge particularly if you were not arrested at the unit. Given the serious charge against you, I suggest that you consult with a criminal defense attorney to represent you in the matter that you have written about.From what you have written about, you should not be responsible from a legal standpoint concerning drug charges with respect to your former rental if you had nothing to do with the placement of controlled substances at that locality.
