public figures drug use

I do not think experimental drug use in college years is fair game for public figures or officials. Going back 5 or 10 years, or however long they have been in the public eye is certainly fair game but I do not think it fair to go back to years of thier lives when they may not have even known they wanted to be a politician or whatever. Also, I think it fair to assume that a majority of people at least try drugs in their lives and in my opionion this is not something someone should be critized for. We're not talking about people having drug addictions but there is no harm is trying a joint 20 years ago.
