and public festivals. but none of this is for matt. he is a military man, and marijuana would be a career-ender. >> i grew up in wisconsin in a well loving family, and i was educated that that's a drug. you don't do that. and i never did. >> but just decades ago, marijuana was a legitimate medication. also called cannabis, prescribed by doctors and dispensed by pharmacies. >> rolling. >> this is harry -- >> but that all changed in 1930. >> a relentless warfare. >> henry ainslinger. for him, public enemy number one, you guessed it, marijuana. thinking guy saw how he could increase the budget of his department by having this mission, going after marijuana. >> you know, saying there is this drug that the mexican migrant workers are smoking, and it's loco weed and it's going the make them crazy and they're going to rape your women.

>> we just thought it was just one rand febrile seizure. >> a fluke. >> a fluke made sense. after all charlotte, nicknamed charlie, was born perfectly healthy, a fraternal twin to sister chase. >> charlie always had big, big smiles. just happy kids. >> easy. >> easy. very much so. >> so it was around three months you said that when you first noticed that charlie had a seizure. >> i was chaining her diaper, well putting a new diaper on from after the bath, and her eyes just started flickering. >> it led to the first of many trips to the er. >> they did the million dollar workup, mri, eeg, spine tap, they did the workup and found nothing and sent us home. >> no abnormal blood test or scan. >> and developing normally too, talking, walking, the same day as her twin. nothing was behind yet. >> by the time she was 2, though, the seizures had become

constant, and started to take their toll on their once happy, joyful little girl. >> she started to really decline, cognitively. and she was slipping away. and she just wasn't keeping up with her twin. >> they finally found an answer, and it was awful news. gervais syndrome. it is severe intractable epilepsy. the seizures start during the first year of life and are unstoppable, difficult to control, and very damaging. >> severe behavioral problems. attention deficit and hyperactivity. the self injury, banging her head on the floor and pulling her hair out. like a possessed child. this isn't your happy charlotte. >> it was a race against time. many gervais kids die young, in early childhood. charlotte was almost 3. for the next two years, the figgies tried everything. strange diets, acupuncture, and dozens of powerful drugs like valium, at van, phenobarbital,

but nothing seemed to help. even worse, some of the medications nearly killed her. >> after one dose, she stops breathing. and after two doses, her heart will stop. >> did you have to do cpr on her yourself? >> yes. i remember when her heart stopped and i had her pulse and i lost her pulse. there was nothing. the ambulance is on her way. >> she survived. >> you're okay. mommy is here. >> but that was fall of 2011. and charlotte was 5 years old. >> when things were at their worst, she just seizes all night. and the kids are sleeping in my room or next door. they can hear the seizure scream all night, 50 times a night. and chase would come in the morning and just misses her twin. and just hug her and rub her head and say i'm so glad you survived through the night last night. >> matt had been deployed to afghanistan. and the only thing he could do to help was start scouring the internet. and he stumbled on to this video

of a child using marijuana. >> so how is everything going? >> jamie had four days without a seizure. >> i was like wow, this having success on specifically gervais, this is interesting. it's natural. >> and while he couldn't ever imagine taking marijuana himself, he was now in the stunning position of recommending it for charlotte. >> i was like we need to do this. >> and i said i don't know. >> there you are. >> and then charlotte's condition got worse. 300 seizures a week. almost two every hour. she was not talking or moving. basically, catatonic. as a last resort, doctors wanted to either prescribe a powerful veterinary drug used on epileptic dogs, or put charlotte in a medically induced coma so her brain and body could rest. for paige, those were not good options. but maybe, just maybe marijuana now was. but she was about to find out how hard that would be.

charlotte figurey had an extreme form of epilepsy. her body was so frail that any seizure could kill her. with no traditional treatment left to try and the clock ticking away, her parents decided to try marijuana. charlotte was just 5 years old. >> i need a card to be able to get the cannabis from a pharmacy. doctors have to prescribe it. >> you need two doctors in colorado to get the card for a juvenile or a child. it was hard. we were the first young child, and they said no. everyone said no, no, no, no. >> certainly her age played a role in my hesitance. >> dr. allen shackelford is a harvard-trained physician. he is also among a handful of doctors in colorado who give prescriptions for medical marijuana. from the moment charlotte entered his office, he knew she was in trouble. while he was just examining her, she had two seizures. >> she had failed everything. there were no more options for her. everything had been tried, except cannabis. >> here's how scientists think it might work.

marijuana is made up of two ingredients, thc -- that's the psychoactive part that makes you high, and cbd, also called cannibadiol. they think it regulates electivity to help quiet the activity in the brain that causes seizures. >> dr. julie holland is the editor of the pot book, a complete guide to cannabis. >> for a long time the work on cannabis and epilepsy was sort of inconclusive. maybe it works. maybe it doesn't. they couldn't quite figure it out. it's only when they really started separating thc from cbd that they saw definitively, yes, cbd seems to really stop seizures. >> so the figgeys needed to find something that was rare, a strain of marijuana that was rare in thc. of course, they didn't want charlotte getting stoned. but also high in cbd to treat her seizures. and that wouldn't be easy. dispensaries and growers, they

make their money off strains that are high in thc. >> i'm joel. >> i'm josh. >> no one knows that better than the stanley brothers. their family business is pot. and if you look at these clean-cut guys and what you see surprises you, don't worry. they've heard it all before. >> when we were round the corner, oh, wait a second. you know, did you finish high school? >> they all not only finished high school, but also college and in some cases graduate school. now they are some of colorado's biggest growers and dispensary owners. they produce up to 600 pounds of medical marijuana a year, and much of that marijuana is high in thc. but here on their remote farm at this undisclosed location in the mountains -- >> it takes a lot of plants. we're allowed to grow six per patient. >> they have been growing something different. something they call revolutionary. >> it's greenhouse one. >> greenhouse one, yes. welcome to it. welcome to paradise.

>> behind closed doors and under tight security we enter what the stanleys call the garden of eden. >> there's nothing like this in the world. >> this plant is 21% cbd and less than 1% thc. >> it took years of crossbreeding plants to get to this point. >> instead of breeding up the thc we've bred down the thc and bred up the cbd, and people said, you're crazy. you know, who is going to smoke that? >> so why grow it then? well, the stanleys also believed in cbd's potential to treat many diseases. and they had seen it change lives before. >> meet 19-year-old chaz moore. he uses many different strains of marijuana. many of them high in cbd to treat his rare disorder of the diaphragm. >> my abs lock up. >> that's why he is talking this way, almost speaking in hiccups,

like he can't catch his breath. it's called miaclonis diaphragmatic flutter. >> it becomes painful. pretty quickly i imagine. >> yeah. >> after, like, 15, 20 minutes this is where i can start to really feel. >> he is about to show me how the marijuana works. he has been convulsing now for seven minutes. >> how quickly do you expect this to work? >> within like the first five minutes. >> and i'm done. like -- >> that's it? >> that's it. >> it was actually less than a minute. >> depending on the attack and the day, like, it will work within the first couple of hits. >> hear how his voice is completely different. that attack lasted eight minutes, but some have last the much longer, and happen as often as 40 times a day. and like charlotte, he had tried so many things before.

by 16 chaz was taking these powerful, addictive, potentially deadly narcotics and muscle relaxants daily, like valium and morphine. >> it would be safe to say that marijuana, what you have in your hand there, is better than all those pills for you in terms of treating? >> yeah. i'm not zombie-fied. i've had 16, 17 attacks today, and i'm still sitting up talking to you. my first attack on all these, i would be in the hospital. >> i'm a firm believer that marijuana has actually saved my son's life. >> chaz's father, sean. >> his quality of life now is 1,000 times better than what it was when he was on the pharmaceuticals. >> a quality of life that paige figgey desperately wanted for her daughter charlotte. but she still had one hurdle to cross, convincing dispensary owners like the stanleys to sell marijuana to a 5-year-old little girl. >> when charlotte's mother called my brother, joel, the brothers had a meeting and said tell us about this patient. she's 5 years old he said, and

a smoke, and receptors are throughout the brain respond, and these are areas of the brain responsible for things like pleasure, memory, learning, sensation, sense of time and space, coordination, movement, appetite and other drives shall we say. so it's sort of an overall impact, right? >> so reward, pleasure, hunger. you have this overall feeling of well being they say. >> that all sounds pretty good. >> it does sound pretty good. >> and it's not just feeling good, but there is this phenomenon reported by many smokers over the years, especially famous artists, the ability to be more creative. >> when you feel that high, there's sort of a release of dopamine, and your brain has the ability now to perceive things slightly differently from the way you might have if you hadn't been smoking pot. what you really see is this reduction in inexhibit -- inhibitory function. >> welcome, doctor. >> pretty spectacular. >> less inhibition.

frustrating, like mixing paint, and then just sort of get into this state of, you know -- >> and why that happens is exactly what columbia university neuroscientist carl hart is investigating. >> exhale. >> research subjects in his lab smoke marijuana and then take a variety of cognitive tests. >> the affects will be disruption in memory, disruptions in inhibitory control. they will become slower. at cognitive functioning, a wide range of things. these affects are temporary, but they're pretty pronounced, and they are clear. >> and it's slowly becoming clear to scientists what part of the brain is most affected. it's the prefrontal cortex. >> it's very important for planning, thinking, coordinating your behaviors. there are tons of marijuana

receptors in this region, and we think that marijuana, particularly in the novice, can disrupt all of those behaviors. >> an impairment that hart cautions could be dangerous. especially when driving. >> you may prematurely hit your brakes. you may prematurely hit the gas pedal. a wide range of things. you may make a turn without looking more carefully. >> look at this experiment done cnn affiliate kiro in washington state. subjects smoke marijuana and then drove. one was a daily medical marijuana smoker and another an infrequent weekend smoker. >> relaxed and buzzed. >> the more the novice user smoked, the more trouble behind the wheel. >> watch yourself. watch yourself. >> but interestingly, the habitual smoker didn't have as much trouble. >> i wouldn't pull her off the road, no. not yet. >> and that's something i witnessed firsthand driving

around with 19-year-old chaz moore. the day that i spent with him, he had been smoking all day long. >> do you feel impaired at all? >> no, i don't. i feel normal. >> turns out when you test people who have a lot of experience with cannabis, you don't see many disruptions, but if you test people who have sort of limited history with cannabis, you can see some clear pronounced disruptions. >> of course, no one thinks that driving when using marijuana is a good idea, but what scientists can't answer is if there is a safe legal limit and people who use marijuana daily as a medicine should be able to drive. how impaired are they? >> what is more clear, though, the effect of marijuana on the young brain. >> what we see is a very big difference in people who begin to smoke prior to the age of 16 and those who smoke after age 16. what we call early versus later onset. >> gruber's brain scans show the white matter, those are the high highways that help the brain

commute from one point to another are impaired in those who start smoking early. >> maybe that there's underlying white matter connectivity differences. >> that's your concern, it sounds like, that those highways, those white matter highways are just more disrupted in people who start smoking early. >> that's what we see. >> perhaps not surprising given what we know about the young developing brain. >> that's a very delicate time in brain development, and that's not a good time to be taking any drugs. >> preliminary research shows that early onset smokers are slower at tasks, have lower iq's later in life, higher risk of strokes, and increased incidents of psychotic disorders. while these studies are not conclusive, some scientists are still concerned because in 2012 35% of high school seniors lit up, and that could mean a generation of kids with damaged brains. many fear something else. >> i never really told myself i needed help. >> a generation of marijuana addicts. when we come back, the truth and the science behind what's being

called a growing epidemic. and, later, charlotte's story. the first and youngest child to try marijuana in colorado. when you realize you need to switch to verizon, it's a reality check. i had my reality check when i'd be sitting there with my friends who had their verizon phones and i'd be sitting there like "mine's still loading!" i couldn't get email. i couldn't stream movies. i couldn't upload any of our music. i couldn't count on it, that's when i decided to switch. now that i'm on verizon, everything moves fast. with verizon, i have that reliability. i'm completely happy with verizon. verizon's 4g lte is the most reliable and in more places than any other 4g network. period. that's powerful. verizon. ♪ the middle of this special moment and i need to run off to the bathroom. ♪ i'm fed up with always having to put my bladder's needs ahead of my daughter.

this was the day chaz moore almost died. pumped full of drugs like morphine, valium to quiet a nonstop 48-hour attack. >> they thought i was going to overdose, and, yeah, it was pretty bad. >> at his bedside his father,

sean, watched his son go from being catatonic to what he calls high as a kite. >> how high are you on the morphine? >> i'm not high on -- >> i watched friends of mine die from taking the same drugs that he took. >> you see, sean was a drug addict, and he had struggled for decades to get clean. >> it was scary. it was important for him not to take these drugs if he could avoid it. >> if he could avoid them. i know how addictive they are. i've seen it. it scared the hell out of me. >> but sean is not scared of marijuana and neither is chaz. >> this right here, i don't get sick off of it. i can't overdose. >> and chaz is right about that. while there are fatal accidental prescription medicine overdoses, every 19 minutes in this country, there are virtually no reports of fatal marijuana overdoses. and it's perhaps one of the biggest reasons most people think pot is safe. in fact, a new study of children

showed that by high school only one in five think marijuana is harmful. that's the lowest number in more than two decades, and it's something we heard over and over as we travelled around the country. >> not really that harmful. >> it has a lot of benefits. not really too concerned about it. >> i think it's safe if you're a safe person. >> but the experts we spoke to said there is more to the story. >> there are people who compulsively smoke, who want to stop smoking, but they can't stop smoking. >> in fact, 9% of marijuana users will become dependent. now, that's not as high as other drugs, like heroin. 23% of users become addicted. 17% with cocaine. 15% with alcohol. it's still approximately one out of every 11 marijuana smokers. >> there's no longer any

scientific debate that marijuana's not just psychologically addictive, but also physically addictive. >> so give me an update. how are you doing? >> dr. christian runs one of colorado's largest youth substance abuse clinics. the number of marijuana addicts he treats has tripled in the last three years alone. >> literally i cried about it. marijuana is number one on their list of priorities. they have dropped out of life. >> back in the day i would have not felt like my day has really started unless i got high. >> joel started smoking when he was just 13. by 15 he was smoking more than a dozen times a day. he stopped skateboarding. he even dropped out of school. >> i like getting high. i need to get high because my brain is telling me. >> adolescence, starting about age 13 have a pretty mature brain reward center. so they can experience rewards and pleasures the same way adults can, but the problem with

that is that their prefrontal cortex, which helps people think ahead, control their impulses, that's not fully developed until age 24. that explains why adolescents are much more vulnerable. >> there's something else that addiction experts believe is likely happening in the brain. when you smoke pot, the feel-good chemicals that make up marijuana called cannibinoids, remember them? they cause your brain to stop producing its own natural. cannabinoids. when you stop smoking, you have no feel good cannibinoids of your own. until your body kick starts production, you feel lousy, so many people smoke again to feel better. and today's marijuana could be more addictive. it has more of the psychoactive ingredient thc than ever before. brain researcher dr. norah volcov. >> if you smoke a very potent

marijuana, then the thc content is going to go very fast into your brain at relatively high concentrations, and then that increases its rewarding effects and likelihood of transitioning into addiction. >> how much stronger is it? >> you see the barbed wire, obviously, on the fences. >> well, i traveled to mississippi where marijuana is illegal, but here on the campus of one of the country's oldest universities, ole miss, a huge stash of marijuana is under lock and key. >> this is our vault. >> this is some pretty tight security. look at this door. >> mahmoud runs what's called a marijuana potency project. what's the potency of this? >> this is about 8%. >> for three decades now his team has analyzed weed confiscated from drug busts. >> this is 36% thc. you can smell it. it has a good aromatic smell. >> how much is this worry you, 36% thc confiscated? >> very dangerous material. for someone that is not

experienced in marijuana smoking takes some of this, and they're going to go into the negative effects of the high, the psychosis, the irritation, irritability, paranoia, all of this. >> while not all the plants are this high, there's no question he has seen a trend. in 1972 the average potency was less than 1% thc. now it's nearly 13%. >> are people becoming more obsessed with high thc marijuana? >> i think so. they're starting out with a half a percent and 1%, and they get a good high, and then as they continue to use that, it doesn't give them the same high anymore, so they seek either smoking more or higher potency material. >> it happened to joel vargas. after a couple of years of smoking daily, joel eventually ended up in rehab where he faced mild withdrawal symptoms like

irritability, insomnia, nausea. >> certainly it isn't anything nearly as dangerous as bankrupt discontinuation of alcohol. you know, for somebody like joel, going rehab is really about learning new behaviors more than it is about sort of treating the physiological dependence or tolerance or withdrawal issues. >> joel has been clean now for six months, but these kinds of risks, they don't scare off charlotte's parents. >> people ask us that a lot. like, how do you make that decision? it wasn't a decision. it was the next viable option. >> and some would say a radical option, marijuana for a 5-year-old. but it was an option they hope would change her life forever. >> baby. >> when we come back, matt and paige figge finally give their charlotte marijuana. the results are shocking. at farmers we make you smarter about insurance,

cbd. that's the ingredient some scientists think helps seizures and also low in thc. remember, she didn't want to get her daughter stoned. she found a small amount in a denver dispensary. the owner was surprised that anyone would even want it. >> they said it's funny because no one buys this. that was the general consensus, no one wanted it. it didn't have any affect. >> paige paid $800 for a small bag and took it home. >> i had a friend that was starting a business making medicine, and i said can you help me extract the medicine from the bag of marijuana? i measured it with a syringe and squirted it under her tongue. it was exciting and very nerve racking. >> holding charlotte in her arms, paige waited. an hour ticked by. then another. then another. >> she didn't have seizures that day. then she didn't have a seizure that night. >> did you sit there and look at

your watch? >> right. i thought this is crazy. and then she didn't have one the next day. and the next day. i thought that is -- she would have had 100 by now. i just -- i know. i just thought this is insane. >> i remember how happy paige was. it's really working. i can't believe it. yeah, that was pretty amazing to hear. >> it had worked. but in just a couple of weeks the excitement was overshadowed by panic. paige was running out of marijuana and the dispensary didn't have any more of that particular strain. even if there was more, the monthly price tag would have been astronomical. $2,000, and not a penny of it covered by insurance. but then paige heard about the stanleys, the six brothers and their greenhouse of marijuana that is high in cbd. >> i said, oh, my goodness. he says i don't know what to do with it. we're trying new things with it, but no one wants it. it's not sellable.

i said just don't touch that because we need that plant. >> at first they didn't want to take the risk of giving marijuana to such a young child. but then they met her. >> tell me about the first time you met matt, paige, and charlotte. >> hmm. >> i'm going to get you misty-eyed. >> yeah, you get all of us crying when we start talking about that little girl. >> the figges had hit the jackpot, a steady supply of high-cbd marijuana, and they only had to pay what they could afford. >> people have called us the robinhoods of marijuana. they say we sell pot so we can take care of the kids, and the truly less fortunate. >> charlotte was the first of those kids. late spring 2012 she tried the stanley special marijuana, and again it worked. >> i can't tell you what that means to us. >> gets you, doesn't it, a little bit? >> if it doesn't get you, something is wrong with you.

gervais syndrome in florida states at present there is no evidence that cannabidiol is effective for the treatment of epilepsy. as does the national institute on drug abuse. >> it is such an amazing turn of events that it really can't be a fluke, but i do still wonder. >> do you still wonder too, matt? >> hell no. >> you know it's working? >> it's working great. >> you just look wonderful. >> and charlotte's doctor, alan shackleford, also agrees. yet his commitment to medical marijuana has drawn criticism. he has even been called dr. feel good. >> how difficult is this for you to talk about as a physician? >> we are typically conservative as a profession and probably as individuals. we want more proof, and cannabis doesn't have that. >> and it's why he has traveled the world to look for researchers who might have the answers. that took him to the place many call the medical marijuana research capital.

>> israel. it might surprise you, but actually research into cannabis and epilepsy started here in the 1970s with studies showed it can reduce convulsions in rats. today shackleford is hoping to start clinical trials in humans there. >> we need to understand it well enough that they won't be reluctant to at least give it a thought. at least try it. >> and it's not just epilepsy, but researchers in israel are studying a variety of illnesses. when we come back, what they're finding up close, and an amazing look inside hospitals and nursing homes where patients are lighting up courtesy of the israeli government. weekdays are for rising to the challenge. they're the days to take care of business. when possibilities become reality. with centurylink as your trusted partner, our visionary cloud infrastructure and global broadband network free you to focus on what matters.

as the sun was rising on the ancient city of jerusalem, the final leg of our journey was just beginning. >> there had been some great advances here, and -- i'm proud of that, obviously. >> dr. boas lev is with israel's ministry of health. here they have pioneered marijuana research. they were the first to isolate thc and cbd decades ago. now the country's ministry licensed 10,000 patients to use marijuana medicinally and has approved more than a dozen studies to treat illnesses like ptsd, pain, crohn's disease, even cancer. >> hopefully this would prove to

be the best medication. i really hope so. we're not there yet. >> the answers might come from places like this. it's a state-run nursing home outside of tel aviv. residents here are using marijuana for pain, loss of appetite, parkinson's disease, and dementia. moshe rut is one of those residents. he was 77 when he smoked his first pipe of marijuana. he is 80 now, and he smokes a couple of pipes a day. it's to help with the pain and the the hand tremors caused by stroke. >> it's a mixture of tobacco and marijuana. >> he even decided to light up during our interview to stop his hands from shaking. >> you are saying your hands are steady because of the marijuana? >> it also helped ease a deeper pain hidden from sight. you see moshe is a holocaust

survivor. when his wife died a couple of years ago, he was haunted by nightmares of his childhood hiding from the nazis. the marijuana, he says, took him out of the darkness. >> you're free. you fly. >> when you smoke? >> yeah. >> there are 19 other patients here. scientists at tel aviv university are now studying their progress. they call the results outstanding. including weight gain, improved mood, pain and tremor reduction. but i can tell you as a doctor it was my next stop that proved the most surprising. this is israeli's largest hospital, shiva medical center. . he is using marijuana to help him with the pain and nausea from chemotherapy. >> filling up the spoon. so that's your medicine inside there. >> you want to take it out? >> and he's doing it inside the hospital.

>> how are you feeling? >> relief. first of all in the muscle in the leg. >> and you're not worried about any potential damage to your body? >> not at all. the opposite, actually. i really believe i can be cancer-free for a long time if i continue, you know, consume cannabis. >> yes, he said cancer-free. very early studies on mice in israel, spain, and the united states are now showing the potential of marijuana to kill cancer cells. it's exciting research, but it is still in its infancy, and it's inconclusive. this program at sheba is well established, and experts say a teaching tool for using marijuana in other hospitals. >> do you think this could happen in the united states? >> i don't know that there's yet enough really concrete evidence of cannabis's benefit that's satisfactory.

at least in that context. i think it's going to come. >> but it could be slow going. >> the fda has been great at approving studies. but national institute of drug abuse has been really stonewalling and blocking any studies looking at therapeutic effects of cannabis, because that's not their mandate. their mandate is to look at the harms of drug use. >> it's very easy to blame an organization. >> dr. norah, who is the director of nida says they are not standing in the way. she claims they are not the only government institute that approves marijuana research. >> if you would come up with a grant that says, okay, this is going to be a treatment for drug addiction, then go to us, but if it's cancer, it goes to the cancer institute. if it is schizophrenia, it goes to imh, the institutes have a mission with certain diseases. >> what is clear, there are bureaucratic hoops that most researchers simply don't want to jump through.

neuroscientist carl hart. >> there are not many people studying marijuana. it's very difficult to get approved to study marijuana. >> what's nice about israel is that the government is helping the research to happen. >> and it's research that could give hope to patients like charlotte figge. scientists in israel are learning that marijuana use might actually protect the brain, not damage it. >> they've been able to show that it can decrease the amount of brain damage from head injuries in mice. >> right. to be able to give a medicine after the injury to reverse some of the damage, that's huge. >> i want to paint my nails. >> you want the paint your nails? i'll paint your nails. >> i literally see charlotte's brain making connections that haven't been made in years. it's almost seeming to build her brain where before it seemed broken. >> and while scientists are still at the early stages of knowing if this is actually happening, i can tell you it was

remarkable to see her progress. in the three months since we first met her, we saw a change. she was now talking more. >> say puppy. >> puppy! >> yay! >> she's horseback riding. >> good girl. >> she even rides a bike on her own. and the special strain made for charlotte is now named for her. it's charlotte's web. >> it is charlotte's plant. >> it's charlotte's plant. not anymore. now it's for all the children. >> more than 41 children are using charlotte's web here in colorado. all of them are reporting significant seizure reduction, and there are dozens more on a wait list hoping, praying that a plant could change their lives. just like it did for charlotte. >> i'm going to get you. >> you both seem very at peace. >> i'm very at peace, yeah. very peaceful. >> we've been given a great life. it's unfortunate that charlie

has this gervais syndrome, but thank god we've got something now that's working. >> she's doing so great today. oklahoma city lies at the geographical heart of the country, it is probably the last place you would pick to be targeted for destruction. then came the morning of april 19th, 1995. >> good morning. in this proceedings with regard to application 95-905 for a ground permit. will present evidence,ea
