True Hash is rubbed. Some Moroccan ladies pick the plant and go through an all-natural process. (sorry haven't had moroccan hash in over 10 yrs. love just sayin it sometimes. lol) Go to the Wikipedia and several other sites for that. Or the "Bubble Hash" or "Ice Hash" methods also produce (what I call Hash)
Oil is typically a refined substance. It can be dried to make hash. The extraction process involves ISO alcohol or Butane, or another foreign chemical. Typically a dangerous process if you don't got you head on strait and not pay attention. These "Honey oil" extractions have been known to literally "blow up" in ones face. So make sure you have a great tutor in teaching. Cheap Butane contains another chem. (methyl mercaptan) which is dangerous to your body as well. I would recommend for newbies. the ISO quick hash (use 90's% iso not the lesser expensive 70's% for newbies if they want to extract. and do it OUTDOORS!!!
Also keep in mind. most states veiw hash different and more extreme than simple MJ possesion. So keep that in mind.
i got my electric burner from Wallmart. I set the burner as high as it will go. When your pan has only a shalow layer of liquid turn it down so the outer part of the pan will not birn. You do not need to turn it down much. it just will make it a littel easyer to scrape the pan
Max, Hash is the solution in the plant that gets you high. therefore by extracting it means one does have to inhale the carsonenic vegatable materials.
Having said that, Dry sifted hash is made of tricomes alone, while "if I have it right" using BHO or ISO method not only extracts THC, but CBD's in any early harvest, or CBN's if from late harvest. Although there is some discussion as to the Bennifits of CBN's, of this is just for those who care about the medicinal uses of Cannlbus>
