If you were stopped by law enforcement, searched and contraband was disocvered upon your person, the police officer had the option of either arresting you, issuing you a citation that you had to sign, or letting you go with a warning.It seems that you were let go with a "warning" so to speak.If you have not been cited or arrested yet, then there is very little chance of it happening in the future. The police officer had his opportunity at the time to do either cite you or arrest you. He did neither.It appears that the police officer simply wanted to put a "scare" into you and nothing more. Hopefully you learned a lesson from this experience.
