California produces a large chunk of the nation's crops despite a shortage of water. The demand for water for cities has created a problem for agriculture that will only get worse. Legal marijuana crops could benefit the state's industry by bringing in more money, employing more people, and using fewer resources.

First, while growing outdoor pot is not especially ecologically benign, it’s far more benign than raising commodities like cattle, rice or alfalfa. Consider: Agriculture uses 80 percent of California’s developed water supply; alfalfa soaks up a full 20 percent of that. The alfalfa is used primarily to create forage for feedlot and dairy. That means that 1 gallon out of every 5 used in California goes to a crop that humans can’t eat.

People don’t make a meal of marijuana either, of course. But measured by water, marijuana barely registers on the California’s water scale. A pound of pot requires, at the outermost limit, 250 gallons to grow, which means that a large serving of it requires about a half pint of water. By contrast, an orange takes 13 gallons water, a glass of wine 32 gallons, and a hamburger 600 gallons.
