The problem with your comments on this subject isn't that you dispute the claim that drug addicts are reproducing at a higher than average rate. No one in this thread seems prepared to discuss, in detail that object-level question. The problem is your claim in the comment I replied to that if drug use did not undermine reproduction we should reconsider whether or not drug use is harmful. The reason why others are downvoting you is because regardless of whether or not drug addiction is conducive to reproduction we still have lots of good reasons for considering it harmful and not wanting people to be addicted to drugs.

As for non-admiral traits being selected for-- there is an obvious example.
