Coke is an oil. Its coke residue at best, at worst, its cutting agent.
Seconded.
I hate to be annoying, but I do think this needs to be said:
Whenever we are dealing with powerful central nervous system stimulants like Cocaine, Amphetamines, Cathinones and so on, we all become more susceptible to seeing random shit that may or may not actually be there. One of the most common tropes centered around Cocaine use is the act of "carpet surfing" once the drugs run out. People spend hours, even days on their hands and knees collecting pieces of dust, seeing Cocaine everywhere.
None of us in our right mind would ever do something like this, yet, even the very best of us can end up surfing the carpet after a little too much Cocaine. Crack, due to its greater potency/quicker onset, is known to produce these behaviors pretty quickly (a person could take two hits of Crack and then spend a couple of hours looking on the ground for more).
What is my point in all of this? It could be this, it could be that; at the end of the day, you're smoking Crack so what really is the difference if it could be nothing? I wouldn't worry about it unless you feel you are having other issues.
