yeah, i often wonder about that myself. Then again, I can't blame Captain Heroin or anyone else, because it was me that entered "can you shoot suboxone" into the google search engine...
I'm also a person that I'm sure none of my friends or family would have thought I would turn junky, and I'm guessing a lot of people on here are probably not street junkies, seeing as we're all using computers, (BTW, I find that's pretty much the only difference, having a computer. I've met a lot of great guys that are down and out on the street). I think that ultimately it is good to have this information. a couple years ago, the only way i knew how to find out if something was safe or not, was to do it, and hope that I would live. Now I can come here and ask questions.
As for shooting bupe, I know for me, it's not a healthy practice, and it doesn't fall into my defination of what my recovery should be. I think if you're using a micron filter, it's a very different story, but shooting corn starch is probably less healthy than shooting heroin. However, at the moment, I'm not so much worried about whether I'm really clean, but more so on how to manipulate my addiction so that I can still afford to have a home, and a relatively normal life.
