dude it is going to be a felony for sure
prosecutors often "overcharge" and actually plea bargain down to what they think you deserve, sounds bullshit but it happens, don't say shit to the cops, and make up an excuse why it was just for your use, talk to your lawyer, even public defender if you have not hired a private lawyer or can't must the cash, talk to them AFTER you have your story down. remember that in no state can a lawyer go along with you making shit up on the stand if they have previously heard you tell a totally different story, and neither can they help you concoct a good story that will make this look like possession for personal use. good luck
