Even in weed-legal utopias like Washington and Oregon, the finances of the pot business are dicey. Because the drug remains federally outlawed, banks won't touch weed money, leaving business-owners without a safe place to keep cash. Others in this situation might invest their profit in art, or vintage cars, or real estate, but these are potheads we're talking about, so they're spending it on ridiculously expensive bongs shaped like Beaker and Big Bird.
