With over half of the country's states embracing some form of legalized marijuana, with a few states even permitting recreational use, cannabis is poised to affect the alcohol industry at some point. And according to a new study, the beer industry stands to lose billions if marijuana is legalized nationwide. The study states, "Cannabiz Consumer Group's (C2G) research findings predict that legal marijuana will "canna-balize" 7.1% of revenues from the existing retail beer industry." Even though the revenue margin may seem small to some, the profit losses are predicted to exceed 2 billion dollars.
