Heroin What drugs would snort that would leave grey/ dark mucus?

[_winded]

Hi,
My boyfriend has been an on and off drug addict for over ten years. Heroin, molly, speed, meth you name it. We have been fighting a lot due to his inability to be honest about his drug use.

my question is: what would cause a dark grey mucus? It’s always one nostril

Who knows? It could be anything... Possibly not even a drug. No one wants to give you the wrong answer and there's not enough info to give the right one
