^ No. you don't just shove pills up your ass you stupid noob! You have to pulverise the pills, dissolve in warm water, and draw it up with a rectal syringe, turkey baster, or whatever, THEN you put the solution up your ass. It would not lead to digestive problems either. You can even combine it with essential oils, soap, or celtic sea salt and do an enema with a douchebag while your at it, which will cleanse your colon.
Thetwilight - I don't think you have a very good understanding of that mechanism. Tramadol gets metabolized once in the bloodstream. Tramadol works on the CNS on it's own too, before it gets broken down. You can even IV tram and still get the same basic effects as oral. They don't make tramadol ampoules for nothing. Their are even tramadol rectal suppositories used in hospitals.
