I was recently caught with almost a ounce of marijuana in a canister with a couple of plastic baggies(the ones from Michaels bought for crafts) in the same canister. The officer questioned me without reading me my Miranda rights and I told him I was selling in order to get my aunt in a rehab program. He also found two vyvance pills which were not under a prescription, he did not however find my scale. If the officer denied that he did not read me my rights would it be possible to convince a judge or jury I'm telling the truth, and would it be possible to convince a judge or jury that I just bought the ounce in specific just to smoke on 4/20 or for chromic pain? I also wanted to add I'm 19 yrs old, I go to a community college in Maryland and it was my first time being arrested and ran through the system.
