here is my story, i hope it helps. so 2 years ago due to a back injury i was addicted to pain medication (oxycontin) and one day i got arrested with half a pill. i got taken to jail and i was told the same thing!!!! that i would have to rat someone out. i told them that i couldn't do that, seeing as how i really didn't want to ruin someones life, when i would probably get some bull shit charge. anyways oxy in the states without a script is a felony crime!! so i went to court a couple weeks later thinking oh my god i am going to jail, cause like you i had no previous arrests or anything what so ever. so i went to court and usually with small amounts of drugs, even felony crimes, as long as its small, they basically just tell you to go home and they could send you a letter in the next 3 years that could summon you to court to be charged. now this is all in the states of course, but my point is, do you think that the court is going to charge you right away and throw the book at you when they have rape, murder, HUGE CROPS of cannabis, crack, cocaine, heroin and whatever else you can think of in a large scale? probably not... now that isnt saying that its impossible, because it isnt.... if i were you i would try to obtain my medical cannabis license. it may not help.. but who knows.. or start going to Alcoholics Anonomys meetings. now that one sounds stupid, because marijuana is a great plant and fuck anyone who says different, but when i was doing pain killers i went to some AA meetings and there were a few people there who had gotten arrested with hard drugs and because they went to AA after they got arrested, the court never charged them with anything. no joke. my opinion is that you will most likely get away with this. this is your first offense and they should recognize that. and remember i am not a lawyer i was just giving my opinion and telling a story. good luck man, you will be alright!
