Cocaine How to get water out of cocaine mix

I took a gram of cocaine and put it in way to much water and ran it through a micron filter. What is the quickest way to evaporate it.

What is the quickest way to shoot two syringes? I tried to backload but I just drew back blood. When I try and shove another pin in I just can't find it and my first shot ends up getting stuck because I leave the tourniquet on to hold it until the next one is ready.
