I am curious to know if anybody over here has had any experience with Tramadol given through the vein route, wether it was for therapeutic or recreational purposes. Also any insight into the pros and cons of using this method would be very much appreciated. Is it worth it? Does Tramadol provide a rush similar to archetypical opiates or does it's SSRI properties also affect the onset of the drug in the bloodstream? I am not a thrill-seeker but has always been interested especially over this pharm, keep in mind that he has no intentions to abuse of it but has access to a rather expensive pharm-grade source (100 mg/2 ml vials )and would like to know if it would be worth the try. He doubts there would be a typical opiate rush due to Tramadol's poor opiate receptor afinity but wonders if it holds maybe another secret?
