The problems arise when you lie about incidents more than the incidents themselves.
If you are asking about a routine criminal background check to determine whether you have any arrests, convictions or outstanding warrants, the answer is almost certainly no. If it does arise, I have no idea what your internship is about, but unless it's with the WCTU, I wouldn't worry too much.
I second that -- I doubt it will affect your internship or haunt you down the road, because the question will almost certainly be along the lines of, "Have you ever been convicted of a crime?"
But read the question carefully, and if you are ever asked about attempting to bring anything into the country, answer truthfully and explain what happened. It could come up in a Pre-Check/Global Entry application, a government clearance, or a professional license (like to practice law). People generally forgive a stupid mistake that happened when you were 19 or 20, but are much more likely to have a problem if they feel like you're currently hiding something from them.
