Hello, I am 18 years of age and last thursday i was stopped by a ranger for going 85 in a 55 which was a construction zone. I was stopped between houston and waco in brazos county. The officer smelled marijuana and searched my car for contraband. He found a gram and a half of marijuana under the front seat, and 5 cans of budweiser in my friends duffle bag. I was with two friends Andrew and John. The weed and alcohol belonged to john but he did not claim it so we went to jail. I took a blood test and a fields sobriety test. My friend andrew is on probabtion and is facing jail time. John just got off probation. i have never had a run in with the law before that evening. I'm being charged with Minor in possession of alcohol and marijuana, and DUI. What kind of punishment am i facing? Is it possible for John to take the entire blame for his alcohol and marijuana?

please respond
