In case of sale, keeping for sale, or delivering, it shall not be necessary to set out the name of the person to whom sale or delivery has been made. In any prosecution for a second offense, it shall not be necessary to state in the indictment, complaint, or affidavit the record of the former conviction, but it shall be sufficient briefly to allege such conviction.
