On the markets I saw a vendor selling HHO, cannabis concentrates extracted using Hexane rather than Butane. Is there a reason Butane is used much more commonly than other solvents, like hexane, distilled alcohol, etc? I'm only curious because the vendor was charging a fair amount more. I wonder if people are buying it for the novelty alone.
Most likely they have used hexane as a dewaxing process. Go check out skunkpharmresearch (dot) com for more info.
