Opana / hydromorphone / morphine = always snort/plug/shoot, always eat = hydrocodone/trams/ codeine/methadone ..And also oxycodone could go both ways ( oral has higher b/a BUT snorting has a very decent b/a too and gives u more of a rush / recreational effects plus anything that drips and is swallowed won't be wasted cuz it will have the oral b/a so it's a win win
