It would be that simple. Under normal circumstances, a source gets busted, you cant use them again. They're busted. This situation is unique in that, hes a source through proxy. So he cant get busted. Only his minions(so to say).
Logically I would hope people would err on the side of caution and just not use them. But I'm realistic. I know people will still use them.
To me harm reduction is about having properly labeled gear, properly dosed gear. Obviously the extreme example
@Dw725 gave, as if you would have to tell someone not to use a source that's bottling aids, if only every decision was that easy.
They'll always be a possibility for legal ramifications. Itll never be zero. So how can legal ramifications come into play towards harm reduction?
