As long as there is no other opiate in your system, then it can be injected.
Precipitated withdrawal only occurs when there are other opiates on the receptors, and the bupe in the suboxone comes through knocking them off, which then puts you into withdrawal because instead of them slowly coming off, they all come off at once.
Your friends most likely still had some heroin in their opiate receptors when they injected the suboxone.
Also, you really shouldn't shoot pills unless you have a micron filter. There are many cases where people shoot up suboxone over time and end up in the hospital or worse due to a build-up of the pill in their circulatory system. I think the build-up can get lodged in some areas. I don't know exactly where, but my point is not to give you the precise scientific medical complications, but rather a warning of the general effects that shooting suboxone may have.
