Just make hash oil using isopropyl alcohol using bud if you're that keen. However, don't go scraping that disgusing black shit off your bong, You'd have to be pretty desperate to want to do that!
Sorry but if that's true, it's fucking nasty. I hope your high is/was worth it
I had a friend like that. One time at a party he took some methadone to get high, but ended up throwing it up into a bowl. Because he didn't want to waste a high he gulped it back down! I know that's a bit worse but still...
I suggest you get a grow on if you really feel you need weed that badly. Or quit.
I have a solution I use over and over for cleaning my pipe. It's black as black can be. I always wondered what might be left if I evaporated it and tried to "clean" it.
