I'm being charged with a felony. What are my rights as a passenger?

my husband and I were parked at the gas station and he was inside when a bunch of cops surrounded my car and came up asking for the driver. I was doing my makeup because my husband was taking me to work and police said they got a call of a reported drunk driver. Which was a lie. When my husband came out they grabbed him searched him and took him to the car. After police told me everything was fine that he was not drunk and they get calls like that all the time. Then they asked for me to get my husbands id so they can run his name because he used to be on parole so I went to get it and they opened my door and said get out of the car and had me sit on the curb. They ran both our names and were going to let us go but searched my car and found norco and soma in glovebox. They asked me about them and I told them they belong to my dad that he is permanently disabled and we live together and use the same cars and go places together. The labels were not on bottles because my car has been broken into so my dad takes labels off so no one can get his info, but has all the paperwork. The police said have my dad bring proof and he did to the station, but in the report he put that I take the pills and he searched my car cause it smelled like marajuna. Thats a lie. I just graduated from the medical field with presidents and honors and 4.0 gpa so I need this off my record before my career comes to an end. I have never been in trouble. Also they let my husband go and I thought when police find something in car not on person the driver goes. Not that I want my husband in jail but I feel it was all wrong.
