Cities and states across the country are either decriminalizing or legalizing marijuana. As the cultural shift toward accepting pot progresses, we chat with journalist Amanda Chicago Lewis for our latest Please Explain about what this means for consumers, and how the industry could become big business for some companies. Chicago Lewis has written stories about the pot industry for publications like Rolling Stone ("Medical Marijuana: A Beginner’s Guide") and GQ ("The Great Pot Monopoly Mystery").
