a week and a day ago my friend was speeding and got us pulled over. the LEO said he smelled pot and searched the vehicle. they found a backpack under the passenger seat where i was sitting. when they searched the backpack they found the weed, a grinder, cigarillos, gram bags, and a scale. my friend and i both denied ownership of the backpack, but i was told by the LEO if i didnt take the blame we were both going to jail. i was only given a class a possession charge, but my sister said if they want they can slap intent to sell on me later. but i was also told by the friend i was in the vehicle with the reason i didnt get intent to sell was because i had a grinder and cigarillos on me which made it clear i smoke. help please?
