plus how to eat less, eat healthier, and still feel satisfied. we begin with marijuana. it's on the ballot next month. the question is this. should doctors be able to prescribe it for medicinal use. being out here, the concept is still controversial and it's confusing to many people. here to talk about it is dr. julie how land. she's an assistant professor of psychiatry at ny university of medicine and also the author of "the pot book:the complete guide to cankacannabis." welcome to the show. >> thank you. >> there are states where this is already allowed, medicinal marijuana use. what do doctors really typically i prescribe marijuana for? are there certain conditions, and how do people know what those conditions are?

>> well, the -- you know, the main indications for using medicinal cannabis are to reduce nash ya and stimulate appetite. it can also be used for chronic pain. it's particularly good for neuropath iic pain, the pins and needles that the opioids aren't good at treating and a good muscle relaxer and helps quite a bit with autoimmune disorders, regulates the immune systems. so it can be used for a whole host of medical indications and psychiatric indications as well. >> it's interesting. the tagli line when you think about it is doctors may not always be the most scrupulous when it comes to prescribing it. they prescribe it for all sorts of different things. what is your impression? it's got an bad rap. is there good record-keeping? how dill janet do you think these doctors are?

>> i think there's a spectrum like anything else. i tlink are many doctors who take their responsibilities very seriously and i think there are probably a good handful of unscrupulous physicians who know that it's an easy way to make money. >> as a medication, if you think about medicinal marijuana, does it seem to make a difference how people would actually take this medication, whether they smoke it. >> yes. >> -- or use it as a vaporizer, what's the difference? >> it does make a difference. first of all, if you have any sort of predisposition to lung problems, diminished pulmonary function, you would want to use either a vaporizer or eat the cannabis instead of smoking it. the issue with eating it youee yat a new drug. thc is the component in cannabis that make you feel altered. when you eat it your live breaks it down to another component and that can feel a little bit more

disorienting or psychedelic. so typically when you eat pot it gets your more altered than when you smoke it and it lasted long wh when you eat it. what's more interesting is people are juicing the whole plant. you don't get high, you get all the medicinal effects from the plant but you don't get altered and because it's illegal and altered you couldn't juice in o'states. there are ways to get the medicinal benefits of the plant without being altered and i think that needs to be explored. >> there was a recent study that talked about marijuana use in young people and say if you use it as a young person it was more likely to have longer term impact in terms of memory degradation. i didn't see that so much in adults. but what worries you the most

about all this? are there certain concerns? >> yeah, there are definitely concerns. kids in their late teens, early 20s, their brains are really vulnerable and susceptible to psychiatric illness. it's a delicate time in brain formati formation. i mean one good thing about regulating cannabis, right now you ask any kid, it's difficult to get pot. dealers don't card. if it's regulated the hope is you would have fewer children usi using. you look at o'countries where they've got much better statistics on teen drug use than we do. >> dr. holland, vial to have you back. we want to look at some of these stories as well. thanks so much for joining us. >> thanks for having me. and coming up, a potential cancer cure for pennies a day. it's a medicine that millions of

americans are already taking. we'll explain. bad breath, oral irritation. a dry mouth sufferer doesn't have to suffer. i would recommend biotene. the enzymes in biotene products help supplement enzymes that are naturally in saliva. biotene helps moisten those areas that have become dry. those that are suffering can certainly benefit from biotene. and the candidate's speech is in pieces all over the district. the writer's desktop and the coordinator's phone are working on a joke with local color. the secure cloud just received a revised intro from the strategist's tablet. and while i make my way into the venue, the candidate will be rehearsing off of his phone.

continuing our series on cancer care now, the cost of some of these medicines we've been talking about can be prohibitive, but i cently spent time at the country's largest cancer center and i found that patients there are often treated with medication that you can literally buy with the change in your pocket. it's an old drug that they hope will be a new kind of cheer. jan chapman volunteers at this animal shelter. she helps pets find loving homes. now if you looked at her, you'd never know she has endometrial cancer. when it came back, the prognosis was terrible. she was told she had a chance of one to five years. that's when she started treating. >> i initially had a lot of the

nodules shrinking and now i've stabilized where nothing much is happening. >> in this case nothing happens is good news. what did it? maybe the experimental medicine. but based on the larger study she was part of, difference maker was a drug she took initially to control side effects. dr. karen lu is part of jan's oncology team and she's talked about metformen. many use it to control diabetes and when doctors started looking at it they saw something striking. >> when they looked at these large group of die bets, they found that those who were taking met fo ormen were having less cancers. >> it's fascinating. >> it is fascinating. >> dr. lu says tumors feed on insulin and it's lowered by the insulin levels so now she's

launching a clinical trial to see if this really could be an effective treatment. >> the question is do we use it in patients once they have measurable disease and, you know, use it at that point -- at this point should we use it when people are in remission? we don't really know. >> what we do know is this. based 207b years of data, side effects are minor and rare and while cancer drugs cost tens of millions of dollars, metformin koufts like 10 cent as day. >> part of that is paying for failures. you see even if the medication is promising enough to be tested in humans, the vast majority those will not work. but that staggering cost and all those false start vd led many to take a new sort of approach, using old medications to find new cures. in fact, we did find another one, m.d. anderson.

this doctor turned it into a treatment. >> this is first drug to be approved in 29 years, so nearly three decades. >> the national industry of health sees the potential. it's offering grants to researchers to see if existing medications of all kinds might have other uses like fighting cancer. >> i think it's going to lead to more important discoveries. >> it's impossible to say for sure what saved jan chapman but she's still taking metformin and her cancer is under control. >> it's made a big difference in my life and my family too. >> it shows some promise against breast cancer and pancreatic cancer too. interesting to note that you're more likely to get all of these cancers if you're obese. less obesity, less chance of

stuttering can be a disability that's so debilitating it forces a person

to shut down, to withdraw, to keep to themselves. well, not so for one young man from toronto. he's found a way to make his stutter disappear and to take center stage. [ rapping ] >> listening to jake rap you have no idea he suffers from a speech disorder that's so debilitating that this 13-year-old used to keep to himself. >> he started speaking at the age of 2 and pretty much -- i mean with single words it wasn't so bad, but when he would get into sentences with a couple of words, two or three words, that's when it started to come out. >> those who love jake knew he needs to get the words out, let him finish what he's speaking or saying. >> but many others tormented him. he was bullied, not only by his classmates but by his teachers as well. >> one teacher was like -- you know, i was just doing this

voice in drama class and i was like, hi, and then the teacher -- i don't know what's more annoying. that voice or your stutter. >> jake's parents robert and v. invested in a lot of time and money for therapy for their son, but nothing worked. then when he was 10 years old, profound breakthrough at a summer camp i was doing this rap battle and it was like, hey, i'm kind of good. >> now jake is performing as li'l jake. smooth as can be. the rhythm or kaydance of rapping makes it easier for him to get it out.

one night last december jake got his big break i got backage at a concert. >> jake's brother cole recorded the encounter and uploaded the video to youtube. so far, 200,000 views and counting. >> it's awesome. i get to go wherever he goes, meet cool people. >> and for all those who used to torment him, the haters, that i now serve as motivation for jake to perform for crowds of up to 20,000. >> my big dream is to have fun and to make music, and it's coming true. >> for jake, the li'l jacques,

stutterer turned rapper and a role model. >> jakes on cnn. let me introduce. >> well, this isn't the first time we've seen something like this, but it's still so remarkable to watch. watch. you know, one reason jake may not stut wher he raps that music relies more on the right side of the brain. language utilizes the left. other tricks that people use who stutter is sometimes a stage voice, a foreign accent. sometimes they whisper. whatever is going on inside jake's head, it could be great to watch, and we wish him all the best. we're going to help you turn into what we call mindless eating. a simple psychological trick that you use on yourself to eat less, eat healthier and still feel satisfied. i had enough of feeling embarrassed about my skin.

[ rv guy ] enbrel may not work for everyone -- and may not clear you completely, but for many, it gets skin clearer fast, within 2 months, and keeps it clearer up to 9 months.

tell your doctor if you're prone to infections, have cuts or sores, have had hepatitis b, have been treated for heart failure, or if, while on enbrel, you experience persistent fever, bruising, bleeding, or paleness. if you've had enough, ask your dermatologist about enbrel.

we're kicking off a new series today called food for life. you're going to see it every

week here on sgmd. it's about how the food that you put into your body affects your overall health. let me begin the conversation that i recently had with new york city mayor michael bloomberg. you'll remember his prosecute-sized sugary drink ban that he talked about here last month. you haven't heard this. i asked him if he had a personal story about dealing with obesity in his own family. >> no, but i can tell you -- and i think i speak for almost everybody -- if it's in front of me, i eat it. i love cheese-its. you put a two-poubd box of cheese-its in front of me. i would eat it all. that's probably not very good for you. if you eat anything in moderation, there's no harm of almost anything, and you put a small bowl of cheese-its in front of me, and it's fine. there's something called the soup test that public health advocates -- or public health scientists use. they put a bowl of soup in front of you. you eat it. ask do you want another one, chances are they say no.

the next day they put a bowl of soup in front of you, and this type they run a bowl of -- a tube into the bowl, and they replace the soup as fast as you eat. a half hour later you'll continue to be eating. we all do the same thing. all we're trying to do is to have a smaller portion in front of you. if you want to take it another portion, you can. nobody is banning you from doing that. you can buy it. matter of fact, you can buy two 16-ounce -- four 16-ounce cup. any time you want to take them all back to your seat or your table. the 16-ounce cup is there. probably won't drink more than one of those, and that would make a big difference. full sugared drinks are different than other kind of things. >> mayor michael bloomberg liked cheese-its so much. the mayor and i were talking about there what's known as mindless eating. i'll ask you a question. how do you know when you are done eating? most people say when there's no more food on the plate.

well, one man i know is dr. -- he is the author of the book called "mindless eating." >> thanks for inviting me in your home today and we'll do a little bit of a kitchen make-over. you're using plates -- it's one of the big things about messed people up. the size of the plate. how much is going on a pasta serve? well, you figure it out on the size of the plate. we find out that people use a 12-inch plate, and it's massive. it's closer to the size we see most kitchen wrshz people using something like this. they're serving about 22% more if they serve on a plate of this size. you want to have your kitchen designed so you pick up the healthy food. let's take a look at what's going in the kitchen that might be maybe biassing when you pick out the unhealthy snacks. we had a lot of good stuff

there. that's cheese. fruits. liquid refreshments. one of the things we find is there are three kinds -- the very first food you see. and the fifth food you see. it may be a lot easier if you were had low-fat cheese sticks if it's visible, and it's fruit for the kids. there's some good healthy things here, but there are other things you're seeing first. it's a lot easier to change our environment than change our mind. bring out a fruit bowl. kids like fruit. this is kind of cool. have you seen people with their junk food cabinet. take these child-proof things and put them on. not that they can't get into it, but it's an additional barrier. >> right. >> have to think about it. >> the solution to mindless

eating is not for most of us. mindful eating. it's easier to change your environment than it is to change your mind. i love what you have done. it's a couple degrees of course correction. >> sure. >> you're right there. >> great. >> brian's work is something called the blue zones project. a blue zone, if you haven't heard the term, is a place in the world where people live measuredly longer, happier, and healthier lives. who doesn't want that? time now for chasing life. >> now, in addition to making over kitchens, brian and his colleagues at cornell set out to see a creative food marketing. that's the kind that's used to show unhealthy kids. we'll see if it could be used to encourage them to eat veggies instead. they overhauled the school lunch menus changing c
