From the information you provided, this situation might constitute a level one felony, which carries a minimum sentence of eight years. However, to provide comprehensive advice, we would need more specific information about the exact charges. Given that the individual was in the car with others, and presuming they didn't confess ownership of or knowledge about the drugs in the car, they could potentially have a robust legal defense.
I would highly advise them to see legal advice given the serious nature of the situation. If they would like to speak to our criminal defense team during a free case assessment to discuss their options and defenses, have them call us at (303) 688-0944 to start.
