Has it been done too much already?

Ok, so I'm elaborating the thought of starting a medicinal marijuana farm. Currently I have many reasons in which I won't go into that I smoke all day everyday and moving to California is inevitable. Would I be wasting my time? I have the knowledge and the resources to pull it off, it's not a question of whether or not I'm ready, but of security, politics, and are too many people already doing it? I know 1 guy in California and 1 in Las Vegas but I haven't contacted them or anyone about what I'm contemplating on doing.

This is my passion, the plants have saved my life and many others. Besides the fact that growing op would be cool as fuck, I really want to help people out just like myself without having to self medicate. Please express your deepest thoughts on the matter, I really need intuitive responses.
