ya, u dont wanna use ur already smoked herb to make hash. U can dry out the RESIN and smoke itm just like you would dry out anything... freeze it or even let it sit in the sun for a while. Ive smoked plenty of resin was i was dry on trees. but if ur gunna make hash, use the leftovers of a plant or you can use the bud itself but I WOULDNT recomend that.
