Honey oil and hash oil are made soaking cannabis (or anything else that contain THC, like hashish, kief, shake, stems, etc) in an appropriate solvent (usually butane, alcohol or acetone), then separating the solvent, evaporating it and collecting the resin that remains, that is the hash/honey oil.
Honey oil has this name because its color resembles honey. Usually its a purer form of the usual brown/dark brown/black hash oil. But they are the same thing.
And honey/hash oil isnt exactly marijuana, but it has pretty much the same effects (usually more intense), as its just a purer form of it.
