Firstly, ditch the SWIM, it's obsolete and unnecessary. Regarding your ton of dust - could well be that you didn't suck hard enough and burn through your crack and that's just residue that can still be smoked. Or it could be shit crack that doesn't melt properly. No idea about cuts, but if you inhaled, then blew out smoke when you put the flame to your pipe, then it's unlikely any dust went through to your lungs, but lung damage is usually the last thing on the crack smoker's mind....until it's gone (in my experience)
