For those of us in states with laws like yours, I think the main security things are:

1) Don't tell anyone.
2) Don't put your refuse in your own garbage bin, or even near yours.
3) Don't sell.
4) Don't smell.
5) Have effective blinds/drapes.
6) Don't be conspicuous, in any way. (Loud parties, many guests, etc.)
7) Don't leave your home with pot or paraphernalia.

If you do all those things, it's pretty hard to get busted. They can't see it, they can't smell it, you don't leave the house with it, there's no evidence of it in your trash, and nobody but you knows about it. Only an act of God can get you caught because they have to have a legal reason to enter your house. If you're renting, that's a bit more scary, because your landlord can let them in. If it's an apartment, then it's also scary, because Joe Smoker next door falls asleep with a cigarette and next thing you know, you're in prison, totally out of your control.
