If there is a commercial pot industry, businesses will have strong incentives to establish and maintain the heavy users who use most of the pot. To get a sense of what this could look like, look no further than the alcohol and tobacco industries, which have found ingenious ways to hook and reel in heavy users. So will private companies be allowed to enter the pot market, or will states limit it to home producers, non-profit groups or cooperatives? Is this approach consistent with our capitalist economy?
