BHO - B.H.O. or Butane Hash Oil is a catch-all name that refers to an extremely potent marijuana concentrate extracted by washing cannabis in butane. The final product is a waxy, resinous material that is vaped in much the same way as dabs. B.H.O. can be in “shatter,” “wax,” “crumble,” or fully decarboxylated “sap.” Potency of THC typically ranges from 80% to 92% THC.
