As Georgia's house has approved a bill to legalize medical marijuana, CNN's Sanjay Gupta discusses the need for more research in the U.S. to break skewed perception.
Speaking on "New Day" Wednesday, Gupta described the bill as very restrictive and said "This is the therapeutic form of marijuana but not the stuff that gets you high. That's what they're talking about... this restrictive bill moving forward to provide a medicine, potentially, out of marijuana."

Choosing healthier foods at the grocery store may soon be a little easier.
The Food and Drug Administration is proposing several changes to the nutrition labels you see on packaged foods and beverages. If approved, the new labels would place a bigger emphasis on total calories, added sugars and certain nutrients, such as Vitamin D and potassium.
The FDA is also proposing changes to serving size requirements in an effort to more accurately reflect what people usually eat or drink. For example, if you buy a 20-ounce soda, you're probably not going to stop drinking at the 8-ounce mark. The new rules would require that entire soda bottle to be one serving size - making calorie counting simpler.
This is the first overhaul for nutrition labels since the FDA began requiring them more than 20 years ago. There has been a shift in shoppers' priorities as nutrition is better understood and people learn what they should watch for on a label, administration officials said.
"You as a parent and a consumer should be able to walk into your local grocery store, pick up an item off the shelf, and be able to tell whether it's good for your family," first lady Michelle Obama said in a press release. "So this is a big deal, and it's going to make a big difference for families all across this country."
The proposed labels would remove the "calories from fat" line you currently see on labels, focusing instead on total calories found in each serving. Nutritionists have come to understand that the type of fat you're eating matters more than the calories from fat. As such, the breakdown of total fat vs. saturated and trans fat would remain.

A promising way to stop a deadly disease, or an uncomfortable step toward what one leading ethicist called eugenics?
U.S. health officials are weighing whether to approve trials of a pioneering in vitro fertilization technique using DNA from three people in an attempt to prevent illnesses like muscular dystrophy and respiratory problems. The proposed treatment would allow a woman to have a baby without passing on diseases of the mitochondria, the "powerhouses" that drive cells.
The procedure is "not without its risks, but it's treating a disease," medical ethicist Art Caplan told CNN's "New Day" on Wednesday. Preventing a disease that can be passed down for generations would be ethical "as long as it proves to be safe," he said.
"These little embryos, these are people born with a disease, they can't make power. You're giving them a new battery. That's a therapy. I think that's a humane ethical thing to do," said Caplan, the director of medical ethics at New York University's Langone Medical Center.
"Where we get into the sticky part is, what if you get past transplanting batteries and start to say, 'While we're at it, why don't we make you taller, stronger, faster or smarter?' "
But Susan Solomon, the director of the New York Stem Cell Foundation, said there are no changes to existing genes involved.
"There is no genetic engineering. It isn't a slippery slope. It's a way to allow these families to have healthy children," said Solomon, whose organization developed the technique along with Columbia University researchers.
"What we're doing is, without at all changing the DNA of the mother, just allowing it to grow in an environment that isn't sick," she added.
A Food and Drug Administration advisory panel concluded two days of hearings into the procedure Wednesday. The panel discussed what controls might be used in trials, how a developing embryo might be monitored during those tests and who should oversee the trials, but no decisions were made at the end of the session.
Mitochondrial disorders are inherited from the mother. In the procedure under discussion in Washington, genetic material from the nucleus of a mother's egg or an embryo gets transferred to a donor egg or embryo that's had its nuclear DNA removed.
The new embryo will contain nuclear DNA from the intended father and mother, as well as healthy mitochondrial DNA from the donor embryo - effectively creating a "three-parent" baby.
In June, Britain took a step toward becoming the first country to allow the technique. One in 6,500 babies in the United Kingdom is born with a mitochondrial disorder, which can lead to serious health issues such as heart and liver disease.
Caplan said the same technology could be used to modify an embryo to "making super babies," a practice he said amounted to "eugenics."
"The big issue over the next 5 to 10 years is going to become how far do we go in pursuit of the perfect baby," said Caplan. "Do I think we're going down that road? Yes. Does it creep me out? Yes. Are you going to be able to draw a clear line? I don't think so."
But Solomon said the procedure is closer to an expansion of in vitro fertilization, which has been available for nearly 40 years.
"It's a complicated science, so people need to understand the particulars of the biology and not jump to calling it something it isn't," she said. The last thing she would want, she said, "is for the New York Stem Cell Foundation to be involved in anything like designer babies."
"I have children and grandchildren, and I can't imagine anything worse."

Obesity rates of children ages 2 to 5 years old have decreased significantly over the past decade, according to a new study published Tuesday.
While there were no significant changes in obesity rates for most ages between 2003-2004 and 2011-2012, researchers saw a sharp decrease in the obesity rates of 2- to 5-year-olds - from 13.9% to 8.4%, according to the study published in JAMA, the Journal of the American Medical Association.
A big part of a child's obesity risk is already established by age 5, according to a study published in January.
The study findings were announced the same day as first lady Michelle Obama proposed new rules to limit the types of foods and beverages that can be advertised in schools and marked the fourth anniversary of her Let's Move! initiative to combat child obesity.
Under the suggested federal regulations, companies would no longer be permitted to use logos of high-calorie products such as regular sodas on cups, vending machines or posters.
The move is part of the first lady's ongoing efforts to combat childhood obesity in America.
According to the new JAMA study, close to 17% of children aged 2 to 19 were obese in 2011-2012. That number has remained fairly constant since 2003-2004, dropping just 0.2%.
More than a third of adults over 20 were obese that same year, a number that held steady over the study's time period. The prevalence is often higher in women and in Hispanic and non-Hispanic black populations.
Four years ago this month, Obama announced that she was taking on childhood obesity with a new initiative called Let's Move! The comprehensive program was part parental education, part government reform - with a bit of celebrity encouragement thrown in.
"About one-third of our children are overweight or obese. None of us want that for our country," Obama said at the time. "It's time to get moving."
Let's Move! had several objectives under its broader ambition of "solving the challenge of childhood obesity within a generation." Obama wanted to increase physical activity and improve nutrition in schools, overhaul nutrition labels to make healthy choices easier for families, decrease the number of calories in restaurant meals and eliminate food deserts - areas without access to fresh, healthy foods - in cities across America.
