This is a pretty big deal. There are tons of farms growing MJ as legit jobs in Cali and Colorado. The problem is that a huge amount of these local farmers sell to people who traffic it to other states. I've seen it first hand as, I'm sure, have thousands of others. One of my friends, more of an acquaintance, got busted hauling a few pounds into the midwest. His lawyer tried to pull the "Oh he's legal in Cali" deal and the judge wasn't having it. Pled out to a felony, but no jail time. He got lucky cuz he had some shrooms as well. He basically got fined his ass off (paid them off).
