Not smoking would likely be working on your side here, however the process to become a licensed grower is quite rigorous, I'd recommend consulting with a legal professional if you're seriously interested. Be prepared for an extremely time consuming and expensive process. If you'd simply like to grow legally, it would be in your interest to get a medical marijuana card, allowing you to legally grow a certain number of plants, Here in Colorado, that amount was 6, it may differ some in California.
Best of luck growing friend!
