Already Been Vaporized
This applies to marijuana that's already been smoked in a vaporizer, and has a very low concentration of thc left.
It usually looks very brown.
It won't get you high by smoking/vaporizing it, but if you have a large amount you can still use it to make edibles (like special brownies).
1: I had an ounce of ABV, so I used it to make some cannabutter
2: What you're going to to smoke that? Don't bother, it's ABV
