WordPress Redirect any pages that are in draft/trash for non login users to the home page

function.php

<?php
//redirect any draft/trashed posts
add_action('wp', 'trash_redirect');
function trash_redirect(){
    if ( !current_user_can( 'edit_pages' ) ) {
	    if (is_404()){
	        global $wp_query, $wpdb;
	        $page_id = $wpdb->get_var( $wp_query->request );
	        $post_status = get_post_status( $page_id );
	        if($post_status == 'trash' || $post_status == 'draft'){
	            wp_redirect(home_url(), 302);
	            die();
	        }
	    }
	}
}

Updated to apply the hook on add_action('wp', 'trash_redirect'); over add_action('template_redirect', 'trash_redirect'); to work with custom post type

@TimBHowe thanks so much for this!
I made a version that allows for redirecting to a custom url:
