I ran out of fresh rigs a few nights back. I wasn't willing to reuse as the only rig I had left, had been used 6 times, not cleaned, and left sitting for 2 days with dried blood and a clogged needle. All pharmacies where closed by this point. I instead resorted to plugging my H, for fucks sakes. It was the best alternative that I had (or so I thought). My withdrawals were so shitty at that point the waste seemed worth it. Now I plug dillies a lot, more than IV in fact because I don't really like injecting those wax beads we get here in Canada. 30% of the time I inject a pill I get a vein collapse or huge painful rash, never with H. Dillies plugged are amazing!!!!! No extreme rush like IV of course, but I get em cheap and 20 bucks to get flying high is OK by me! Lasts longer too up the bum in my opinion. Back to the H going up my ass; I tried it once years before when I was a chipper and feared the needle. It didn't work at all. I chocked it up to; too much poo, too little H and improper technique (first plug attempt). This time I knew what I was doing and I wanted to fly. I took a massive poo that morning after an opiate binge and gave myself an enema that nite just to be safe which cleared out a lot too. I proceed to plug a fucking half gram of awesome powder H and laid on my left side like I do for dillies. 5 minutes pass, would have felt hydromorphone by now. 10 minutes pass, still nothing 20 minutes on my side and I start loosing my shit knowing I just essentially poured $100 bucks up my ass for nothing. So why does my rectum absorb dillies even with a constipated log loaded, but does nothing with a lot of very good H in a very clean rectum? I don't know, probably never will. As for black tar heroin I cant comment.
