Take dried marijuana and crush it up into a fine powder.
Put the powder in a jar with 100% pure Isopropyl alcohol, so the alcohol covers the powder.
Soak in a dark place for anywhere from a couple of hours to a few days.
Pour the mixture through a screen onto a glass plate. A fine kitchen strainer or gold coffee filter work well.
Evaporate the liquid carefully. This can be done either by letting it sit out in a warm place or by heating it up. If you're going to heat it, be careful...it's flammable. Do it someplace with good ventilation, preferably near a kitchen exhaust fan that blows outside.
Scrape up the tar with a razor blade or spatula. Try to choose a pan or bowl that won't be harmed by a razor (glass?).
If it is too sticky, add a little dry powder till it attains the consistancy of silly putty. Work it over and over. This seems to make it bind together. Practice makes perfect.
Use in any way you'd normally use hash!
This is better than any imported hash I've ever found. Burns slow at a low temp, so I think you get more THC. It makes a little pot last longer. I know people who go through a half an ounce weekly smoking the bulk material, a quarter will last a week if extracted. A different high altogether, light and trippy. Kind bud makes a gold tar and is SOOOO sweet!!!
