Ohio law in regards to marijuana used to be ( back in the mid 90's ) that if you have more than 1 bag, no matter the weight/measure, then you can be cited for intent to traffick. If you have 2 or 3 doobs in the same bag, its simply posession....but if you had those same 2 or 3 doobs all in seperate baggies, you can be cited for intent. Anything over 100 grams can be considered felonious posession WITH intent to traffick due to the large amount. Been a long time ago though, so laws could've changed since then. I'd assume that concealed compartments in your vehicle would be perfectly legal pending no residue is found inside it. Personally, criminal drug history shouldn't even play a part in deciding whether someone could/can be cited for simply having a concealed hideaway in their vehicle as long as there's no evidence of it ever being used as an illegal stash. Now, if you buy a used car that already had a "dirty" hideaway in it somewhere and you get stopped by a K-9 unit....sad to say but, clean record or not.....good luck proving you're innocent
