Oh yeah, the so called sin taxes.
What about the people that don't want to pay a 'sin tax' ?
A little pot is a whole lot easier to product then beer, whiskey, tobacco or just about anything else the Taliban (Christian or otherwise) want to tax as a sin.
That's why its still illegal (mostly), because when push comes to shove, the money ain't there unless it is illegal. That is the only thing that gives it value.
One can already buy clones (read specialized hybrid) in the 'marketplace' for as little as $30 to $ 50 apiece.
Dig a hole, throw some chubs from the local river into the hole, plant your seedling/s. Cozy up to the fire come winter time.
Uncle Sam can take a hike.
