You can go to the booze store, or you can brew your own, but few people do.

Growing pot is a lot less trouble than brewing. Cannabis literally grows like a weed. 

Growing your own would be a lot safer than trying to distil alcohol yourself.

The big only market I see is for folks who are willing to shell out bucks for a brand.
