It's pretty much legal to grow it, own it and smoke it in California so that didn't end the violence.
Actually that is not true. If you can afford a medical MJ card and if you can get a Dr. to approve you for one, then you can grow it and own it, but still there are limited amounts a person has to adhere to. It is not the same as legalizing it. Plus, until they legalize it across the country one state or so will make no difference.
