Gone to Pot

S8 E19: (10/21/2013) According to government data, more teenagers are smoking marijuana today than cigarettes. And, while other illegal drug use is declining, marijuana is on the increase -- and consequently, so is demand. In California, illegal marijuana farms are springing up by the thousands deep in the back woods and far from prying eyes. These are not small backyard grows but major plantations of pot run by organized crime. So much illegal marijuana is being grown in California that it’s devastating the local environment. In a state plagued by drought, marijuana farms are using up desperately needed water. And let's not forget the fertilizers, pesticides and rodenticides, many of them banned in the U.S. years ago, that are being used by many of the illegal growers -- these chemicals are winding up in California's soil and water -- not to mention the pot itself.
