Although it requires capital, you can purchase home extraction equipment to make pot juice. Is this anything new? Not really. The equipment has been available for people who like to extract oils from botanicals to make all manner of oils, tinctures, perfumes, elixirs. The marijuana magazines I get in the mail are loaded with ads for industrial strength extraction equipment. So getting into the business is a lot cheaper than, say, cranking up a steel mill, adding a lane to an interstate highway.
