California has become one of the most aggressive states in banning smoking and now state lawmakers are at it again. One Southern California assemblyman is trying to ban smoking in your own car if young children are riding with you.

It isn't law yet, but the bill has already passed its first hurdle in the state legislature, with a 12 to five vote.

Smokers all across the state are probably asking themselves, what next? California has banned smoking in restaurants, bars, some beaches. Soon, you may not be able to smoke in your own car, if young children are inside.

"It's almost taking our rights away. So what is big brother going to do next?"

Smoker Robert Campbell already chooses not to light up in his car, but says that's not the point.

"I don't tell them what to do in their house, they shouldn't tell me what to do in my car or anywhere else."

If this measure passes, it would be the first law of its kind in the country. The law has already passed the assembly appropriations committee. But it has lost some steam.

Originally, its author tried to ban smoking in cars anytime there's a passenger under 18. The way the bill reads now, if there's a child under six in your car, you can't light up. We did find people who think this is a good idea.

"I think it should be banned completely."

Even if it means taking away personal rights?

"You can look at it that way, but I think in a confined space it's not good for anybody."

But even some non-smokers say making smoking in your own car illegal might be going too far.

"I don't think it should be a law, but a parent should do that anyway."

State taxes are already almost doubling the price of a carton of smokes. If this law passes, smoking in your car with young children could mean at least $96 more if the officer gives you a ticket.

So for smokers, the price of lighting up just keeps going up.
