Iso Hash. Look it up. Dont smoke it. It is very very bad for your lungs. You can do shit with it besides Iso Hash. You need some strong rubbing alcohol(Isoproply Alcohol 99% i Think). Take your bud and let it soak in the rubbing alcohol. Once the alcohol is saturated with THC you let it evaporate leaving you with a nice amount of hash depending on how much you use.
