"The prosecution of many drug offenders is discretionary and can be subject to either state or federal jurisdiction. Frequently, state cases are transferred to federal prosecutors in order for the defendant to face stiffer penalties in the federal system. The potential of facing a mandatory minimum or a Guideline range sentence that is significantly longer than what one would face in state court increases the likelihood that a defendant will accept a plea bargain."
