OXFORD, Mississippi (CNN) - The average potency of marijuana, which has risen steadily for three decades, has exceeded 10 percent for the first time, the U.S. government will report on Thursday.
Scientists working for the government predict that potency, as measured by the drug's concentration of the psychoactive ingredient THC, will continue to rise.
At the University of Mississippi's Potency Monitoring Project, where thousands of samples of seized marijuana are tested every year, project director Mahmoud ElSohly said some samples have THC levels exceeding 30 percent.
Average THC concentrations will continue to climb before leveling off at 15 percent or 16 percent in five to 10 years, ElSohly predicted.
The stronger marijuana is of particular concern because high concentrations of THC have the opposite effect of low concentrations, officials say.
In addition, while experienced marijuana users may limit their intake of potent marijuana, young and inexperienced users may not moderate their intake and possibly suffer from dysphoria, paranoia, irritability and other negative effects.
Here are the big stories on the agenda today:
Wednesday’s American Morning "robocall" segment piqued viewers’ attention, as many reported their own experiences with the irritating scams.
Have you been the victim of a robocall? Do you listen to the pitch or simply hang up? Has your cell phone bill increased because of these calls? Tell us about your experiences with robocalls.
Social security and Medicare were considered “old” issues that have remained on the “back burner” too long and simply needs to be fixed.
How do you feel about the current situation with Social Security and Medicare? Will universal health coverage help to solve many of these problems? Is there a better solution?

We’ve all received them – phone calls from a machine saying the warranty on our car is set to expire. It seems the "robocalls" are annoying to everyone, including lawmakers.
New York senator Charles Schumer got one of those calls. And now he's working to put an end to what he is calling consumer fraud. He spoke to Kiran Chetry on CNN’s “American Morning” Wednesday.
Kiran Chetry: I got confused and I am sure other people get confused. I thought they knew it was my car. I thought they knew what they were talking about. And so it really is not only an issue of annoyance but also that they're not pedaling something that's legitimate. Is that correct?
Charles Schumer: This is consumer fraud, A-101. Yes, they call everybody. They call randomly. They call people who don't have cars. But unfortunately there are too many people who are gullible, particularly with everything going on with Chrysler and GM. And they ask you for your credit card and they take $200, $250 off. And, leave you open to credit card fraud. So first job here, consumers should not respond to this. If you're worried about your car warranty, call the company that issues the car.
Chetry: You and your colleague Senator Mark Warner want to do something about it. You want to ask the Federal Trade Commission to take action. How big of a problem do you think this is, besides being a nuisance and what do you hope the FTC can do?
Schumer: Well, we know that just about everyone has gotten these calls and repeatedly. By the way, another minor annoyance, when you press two, they still call you again. I pressed two the first time I got the call and I've gotten them three or four more times. There are four levels of problem. A) It's annoying. B) They have pierced the Do Not Call List. You notice, you don’t get cell phone spam much, except these folks. Third, of course it costs money if you don't have the right plan. But worst of all, many people are duped and lose lots of money for no reason.
We've asked the FTC to do a full-fledged investigation of this. It shouldn't be hard to track down who these scammers are, because after all, you follow the money. They've got to get the credit card and cash it in. The FTC has been very cooperative. They sent us a letter yesterday saying there's an investigation in progress. And we look forward to hearing from them soon about what they're going to do about it. They have the powers. This is a criminal violation of law. And they have the powers to go after these people. We just need them do it.
