Marijuana wax (budder) is a cannabis concentrate that has the consistency of ear wax. This is made from a butane extraction — hence the name Butane Hash Oil, or BHO. The butane is pushed through the cannabis plant material, leaching out all of the essential oils. Those are collected, the butane is evaporated and then vacuum purged off, and you are left with your BHO in a wax form. Wax is easy to handle but is often less stable and doesn’t last as long as shatter.
The buds of marijuana are packed really tightly into a tube and then blasted with butane, which is a highly flammable liquid. The process of doing this extracts the THC from the marijuana in a really concentrated form. What comes out is a thick, hard, wax-like substance that is highly hallucinagenic. Basically, the reason that this is really dangerous is not just for the reasing that you are combusting something really flammable. There have been victims of the wax explosion in the process of making it, and is a lot like the process used to make meth or cocaine. It’s vapors can fill up a room if it isn’t fumigated properly or you aren’t well enough prepared, and the fumes are a health hazard, too. So please don’t try this at home!
