posession of marijuana law in the state of california

so i just recently got caught up with 4-5 grams of some koosh. but the thing is it was on the ground near me and another person under a table we were sitting at.

my story is, i just got there right when the cop pulled up. it was either between me or one other person he thought it was, but everyone told him that we didnt know it was there and kept to that. so he searches me and finds $80 on me and then starts to ask me about selling bud, but i denied it. and he also thought i was high at the time when i wasnt.

can anyone tell me can i be chargedand convicted with this bullshit?

 

my bad, wrong section of marijuana forum.
