actually if you only have your county card it means you can only smoke in that county... or city card.... like oakland card u can only smoke in oakland. frisco means only frisco..... and if u get pulled over in your car then u are only covered in that county... yeah your perscription will cover you for your illness... if you get oulled over with a county card the cop can take your weed n take you to jail just for the hassel till they clear everything up... but your state card protects you from hp... and state police...
