Was the dope in wax bags? If so I would think little of the Green Works hit the diesel. Me personally (and I'm a "fuck it, I'm gonna do the drugs anyway" kinda guy) would do a 1/4 bag or so and see how I felt. If okay, then I'd go for it and get it on, but that's me (obviously, I'm not an HR fanatic because, if you jab needles into yourself to inject heroin, then how much value are you placing on your own life?).
Reading this reminds me of a girl years ago that came to my house to score dope. She had 40 bucks, enough for 2 bags that evening, and 2 for a wake up. I sold her the bags and she needed to bleach an old rig of mine because she didn't have rigs. The chick accidentally put bleach instead of water on her dope. She looked at me, almost in tears, and said, "do you think it's still safe to do"? I laughed and said "yeah, it'll be fine". She was actually drawing up the shot and I had to actually explain that I was kidding and that she needed to do the other two and figure something to do tomorrow. In my soft heartedness, I fronted her a wake up bag (and I knew full well that she wasn't going to pay me for it, I just hate to see people sick). Anyway, if you sniff (or even if you inject, sniffing more is better than flushing the diesel), I would say fuck the mucosa irritation and do the dope if you are physically dependent.
