This question cannot be answered without more information. For example, there are five degrees of felony drug possession ranging from a D felony to an A-I felony each carrying a different sentencing range. Your question should be presented to your attorney who should be able to give you an educated opinion after reviewing your rap sheet, your current charges and your prior sentence terms. In the maentime, I recommend that you exercise your right to remain silent and only discuss your case with your attorney.
