Nah, I live in the Bay Area. Cops usually don't give a shit. And it's not like we're in an apartment. We live in a house. And I didn't have a big ass garden. I only had 2 plants going.
I didn't just say, "Go on ahead and search my house." I repeatedly said I wasn't the owner of the house, and I couldn't let anyone in. They kept saying they had to do because it was a 911 call. But hell, they could've been making that up for all I know.
But as far opening myself to a "potential shitload of legal problems," I don't think so. I am a legal MMJ patient with my doctor's recommendation, and I was well within my county guidelines for cultivation. I have absolutely no worries.
Do yourself a favor and check this site for all the MMJ info you need:
