>If you do cocaine you can practice harm reduction by washing in acetone, and if you have it available, cloraform.

I'm gonna be real with you. A product that's washed like that, especially by an amateur at home (e.g. you or me) doesn't sound like something I want to sniff up into my nose.

Acetone and chloroform are both extremely volatile and rapidly evaporate leaving no residue. In fact in the lab people use acetone to help dry glassware of water. There's nothing dangerous here.

Maybe if you get pure acetone like a lab would. The acetone I've had experience using from auto parts and hardware stores definitely leaves streaks on glass and clothes smelling of chemicals.

And if you use that, you’ll pour all your cocaine down the drain. You need the 100 percent pure anhydrous stuff. They don’t sell that at the hardware store.

Acetone is not something you should purposely expose yourself to but it is also not an especially dangerous substance. The human body produces small amounts of it during normal metabolism; more if you're diabetic or drink a lot of alcohol.
