[ARC5] MEK, benzene, acetone for Q dope.

[Peter Gottlieb]

Hey, like I said, feel free to use such solvents. I still maintain that others should look further than this group for determining the risks. Carbon tet for example has been shown to cause liver damage. If that and other toxic effects don't worry you, have at it. 

If you're going to call me a nut case for having such concerns then I am ok with that. Just don't ask me to pay for your dialysis.
