Bong water
I'll stick with rum and coke!
That said, I did discover a good use for bong water back in the early 80's.
Take really filthy old bong water and pour it thru a coffee filter.
It comes out a nice yellow color...Looks like piss...
If you apply it with a cotton-ball, there is no better medicine to use on poison ivy or poison oak...
The itch goes away and the blisters dry up and heal very fast
