Who would ever think of drinking drain cleaner, or camp fuel, or brake fluid? But every day people ingest this stuff and worse when they inject or smoke meth.

The addiction is so strong --- users have figured out how to bypass current laws to get pseudoephedrine to make it. That's why Kentucky lawmakers are considering Senate Bill 45."

But customers are already limited to how much pseudoephedrine they can buy in any given day or month, so why is this new law necessary?

I accompanied some undercover drug agents to see just how easy it is for any adult to get meth's main ingredient.

Pseudoephedrine is found in common cold medications like Sudafed and Claritin-D.

The current law limits your purchase of the drug to 3.9 grams per day and nine grams per month. But meth makers get around this by having several different people buy their limit of pseudoephedrine every month.

And they're buying a lot of it! One pharmacist told us: "50 to 60% of the products containing pseudoephedrine that we sell, is very likely, that those products are being diverted."

And they make good money doing it. Bowling Green/Warren County Drug Task Force Executive Director Tommy Loving says: "The pack of Sudafed that you purchased for $8 or $10, can be resold to a meth cook for $50 so it's created a black market."

And it leads to other crimes. "In order to get the money there are robberies, there are all sorts of other crimes going on in relation to methamphetamine, not just the purchase of pseudoephedrine," said the pharmacist.

So to stop this practice, authorities want to make pseudoephedrine available by prescription only!

Prescriptions for pseudoephedrine are already required in Oregon, where the number of meth labs discovered by law enforcement plummeted from 584 in 2001 to just 13 in 2010. Mississippi saw meth labs decline by 68% after they passed the law July 1, 2010.

And what are the chances the law will pass in Kentucky? State Representative Jody Richards isn't sure, but he supports the bill because of the children involved.

"Children are in these houses a lot of times," says Richards. "A child in 2009 was killed in a neighboring county or a nearby county. Others have been affected."

That child was a 22-month-old boy in Wayne County, who died after swallowing drain cleaner police say his teenage parents were using to make meth.

So what would happen to meth labs if Kentucky doesn't pass this law?
Tommy Loving says, "If we don't change this law and do something about it, I'd say we could very easily hit 1500 for 2011."

It's important to note every pharmacy we visited followed the letter of the law in running the e-tracking "Meth checks."

In fact, the system did stop one of our undercover agents when he tried to buy more than the allowed 3.6 grams of pseudoephedrine the day we made the buys.

But it didn't keep our entire group from getting 12 boxes of cold medicine the bad guys could have bought to sell to meth-makers for a 500% profit. Tommy Loving says the new law would correct that.
