Supposedly I was driving outside of my lane on a road and I was pulled over by an officer who might have been following me for 60 seconds. I told him that there is construction and it is hard to see the lanes. He still had me take a sobriety test which I believe I passed without a problem. The officer said he smelled something although I didn't and he told me he needed to check the car for drugs. He found a very small bag of marijuana in the glove compartment which I didn't know about. I honestly didn't at the time and I have no need to lie here. I was arrested for a very small amount of marijuana possession and a suspected of driving under the influence. I was eventually released and I couldn't figure out how it could have happened. I called a friend who was riding in the car with me the night before when we went out to a party. It turns out it was his little baggie. He put it in the glove compartment and forgot about it because he didn't want to have it on him at the party in case police showed or something else happened. He is a little paranoid. Now I have a problem. What should I do?
