Marijuana can even be used as "Biomass" fuel, where the pulp (hurd) of the hemp plant can be burned as is or processed into charcoal, methanol, methane, or gasoline. This process is called destructive distillation, or 'pyrolysis.' Fuels made out of plants like this are called 'biomass' fuels. This charcoal may be burned in today's coal-powered electric generators. Methanol makes a good automobile fuel, in fact...
