Saw too many people fall into K-holes to ever want to try the stuff. I did a lot, 'cept the opiates. Only time I ever had that was morphine twice in the hospital, and demoral once in the hospital. Morphine was disgusting. I didn't like it. Just felt like a dirty high, itchy and slow. No pain though.
Demoral though. That's some potent stuff that made me realize how fuckin' dangerous opiates are. Felt too damn good.
