Ecstasies, all of these are must easier to study. The catch 22 facing marijuana researchers why lawmakers are keeping them in a purple haze over how weed works. And getting it moving, a new burst of Political Energy will it be enough to push forward a stalled energy project. Her saying 0,000 jobs thats a lot of people thats a lot of families. Thats a lot of kids being fed. And a lot of people not on welfare, and sucking off the government. Communities in the path of the pipe line, the keystone xl extension, gearing up for a final fight. And this is america tonight, thank you for joining us the shock has not worn off. Highest alert and deepest mourning. The most iconic figure on the paris skyline, fed dark while rising in demonstrations across france an am imagine to the journalists who died daring to speak out in the their satirical journey chablis member doe. To challenge their killers the magazine has vowed to print 1 million copies more than its usual run. It is hard, but we will do it anyway because stupidity will not win. A resolute promise, Law Enforcement now warming the country side, where there has been little sign of the suspects blue reason to believe they are still very dangerous since early this morning elite units have swarmed over the country side, about 60 miles north going door to door, searching everywhere. Houses farms stopping vehicles. Looking for any possible hiding place. A search that is gripped france. Overhead Police Helicopters swarmed, and Police Vehicles raced over rural roads. It all began when a car abandoned by the two suspects brothers cherif and careef, was found nearby. A man told me they had left their car and gone into the forrest. And to avoided the forrest road. A pump attendance told police he recognized them, there were weapons on the backseat of the car. That brought the special Police Forces into this area, focusing on the area to the east. Nearly 60 square mites. There are many buildings and farms. Police helicopters searched into the night that the suspects has again slipped away. What is known in the word of frances prime minister, is that the country is facing an unprecedented terror threat, one that overnight has bubble double the number of soldiers to the streets and sites of paris, with more reinforcement on the way. And secure has been stepped up at almost every public place. A level of security, that by order has now been extended to the rural lane, 60 miles north, with late tonight Police Declare the search there over, at least until daybreak. Where are cherif and cherif kouachi, and will they strike again . One of the big concerns that has come up is there may be backlash. Yes there has been signs of that. Local towns and villages, there has been demonstrations that have turned violent. It is hard to say that there is an exact association because these are communities that are troubled anyway, but it is striking there have been this number of attacks against islamic entities in france. In just these wont four hours. Now we have learned quite a bit more, or at least the police have learned is quite a bit more about the brothers the suspects in this case. And what they left behind. Well, what they left behind is very telling. In that black car the car that we see at the site of the initial shooting at the magazine Charlie Hebdo when they crashed that car, and had to hijack another one they left behind molotov cook tates and jihaddy flags. It is also clear they left that building under their own timing. They were not forced from the building they could have stayed there and made it their final stand instead they made a deliberate effort to leave materials found in the car very strongly suggest they had Something Else planned and they may still be attempting to execute it tonight. Question are now more than 36 hour into this. And Counter Terrorism expert as well. Something that may be laying in wait for. Right now we dont have a sense of whether a Second Attack will occur but it is always a risk. You have had disruptions in the past, and when they have fred theres always they will carry out an attack. You have had attackers carry out secondary attacks. Think of the d. C. Sniper where they carried out attack after attack, in this case because they have brought down the entire wrath of the french Intelligence Security opera us the upon them, you have to think that they may have had Something Else plans right away the fact they didnt get to bring the molotov cocktails with them, that maybe they have been disrupted but if so, and they had something planned, they are probably going to try to figure out right now how is it that they can reconfigure and do Something Else dramatic. And one of the other things that has been talked about a lot is what sort of training or who might have launched this attack. Who was behind these individuals. And increasingly, the u. S. Officials are thinking that al quaida was responsible. Today they have increasingly pointed it in that direction. We do have some data points the fact that they said they are part of al quaida to the cartoonist and you have the older brother as well having spent time in yemen i wouldnt call it definitive. But there is a strong reason to point nit that direction, if so, they may have received training in yemen, and syria it remains to be seen what kind of training where as we have talked about yesterday they did make errors. And that doesnt mean that they are not trained it just means they are got up to the standards of special forces. We heard from the French Justice minister, the focus was on the younger brother because he had a criminal record, for association with the jihaddy network he an association with al quaida in arrack during the time of the war. Today the menster came out and said that the elder brother had in fact been the one who had traveled to yemen and that it appears spent time with al quaida in the arabian peninsula. At this point, we dont know when french officials became aware of his travel. Was it before the attack . If thats the case, it makes the lack of surveillance, or apparent lack surveillance of the two even more puzzling. Which also is very striking because we are looking at 36 hours plus, from the initial incident, france is a big country, but not even as big of the state of texas, they have put everything that french Law Enforcement has. Into this area, and yet what we are seeing is theres one witness who may have been able to off some idea of these guys in the car. The car they were driving this morning is apparently the same car that they fled paris in 24 hours earlier. Where did they go . How did they evade cameras on highways in where did they put it overnight who helped them. And someone helping them that is a concern . Absolutely. One questions that exists here is how big does this operation go. You have had a bit of a police round up, they have certainly arrest add number of people, and they will be applying every technique they can. But is it what kind of support network existed. Do they have safe houses or people who are trying to help them. And that is the possibilities that they have, both to get away and also to regroup and carry out a Second Attack. Also, why have why did they go to the area where they were . The area where the police searched all day intensively for them. Is an area that is about 60, 70 miles north of paris. Why were they there . Were they there to head paing towards paris . Were they going someplace else were they heading to those woods . Do they this is an area they know and plan to go to. Do they know those woods. Sheila mcvicker with us, thank you very much for being here. In a moment, reconsidering the burden of proof. In our endowment look at a year on pot correspondent records on the hurdles facing marijuana scientists. How can they prove weed works. All we have to do is get the drug and study, for marry wayne that, we go into a whole other series of reviews. Why that is, and why it may prevent more bids to make medical marijuana legal thats in our next segment. Extreme shocks the face, with the wind chill went to 70 below. Its a chilling and draconian sentence. It simply cannot stand. Its disgraceful. The only crime they really committed is journalism. They are truth seekers. All they really wanna do is find out whats happening, so they can tell people. Governments around the world all united to condemn this. As you can see, its still a very much volatile situation. The government is prepared to carry out mass array. If you want free press in the new democracy let the journalists live. We hear, often about the supposed virtues of medical marijuana. Legal in two dozen states already, and if more looking to join in legalize recreational pot, you may suspect that Health Questions may have been resolved but it turns out that the data of the science is a black hole, one they have found tough to fill. A year on pot examined the hurdles facing researchers. Here is science and Technology Correspondent. Aaron hind was 18 years old, when he went to fight the iraq. A couple of times a couple people in my company got killed. As with so many others the trauma of war followed him home. I would be at a park. And all of a mud brain would Wander Around thinking what would this scene look like if a bomb dropped on it. The side effects were too debilitating then he started smoking pot. It allows me to focus on daily tasks. That i normally might be into too much agitated to be able to focus on. It allowed me to enjoy my life. He is one of 20 million american whose use marry want facing marijuana on a regular basis. Here in california where medical marry want facing marijuana has been legal since 1996 more than half a Million People are registered to use it. It is estimated for the entire country legalized there would be 2. 4 million regular medical users alone. These are huge numbers, but here is the thing, it is uniquely difficult, to study marijuana nobody can do it, and just because a couple of states have legalized has not made it any easier, a lot of people seem to feel that marijuana may have potential benefit, but right now even as the country consumes as much cannabis as it is, it is still almost impossible to know anything for sure about the long term effects of consuming it. In fact, even as states are passing world changing laws they are based on nothing but anecdote, and thats because federal law has stifled research we dont know how pot effects driving or life expectty, or really anything. We certainly dont know if the it can treat a soldiers ptsd i am dubious of the proposition that it will treat dbsd a Senior Research scientist for the department of Veterans Affairs. Vetted remembers are using it in massive numbers it feels as though it would be in their interest, to get around the restrictions and study the heck out of it. Yeah, veterans are a population for which marijuana is important to understand. And i agree with that, the va isnt really positioned to do that right now. I can go out and tell a doctor i am suffering from anxiety and bring it back to my office and use it legally but if instead i want it because i want to study it, i want to find what is its effect on the brain and body, that would take me years and thats crazy. Heroin, cocaine ecstasies all of these are must easier to study than marijuana. Brad budger works for a nonprofit working to legitimize pot nationwide as a prescription medicine. If we are studying aspirin or prozac, or lsd thats it. All we have to do is get the study drug and start the study. For marijuana we into a whole other series of reviews. To study cannabis, researchers need approval from four separate government agencies. And an open ended Public Health review, unique to pot which can stall research forever. We have been working on getting a study started for ptsd for 12 years now and that approval is just to purchase it. And the only legal supplier of marijuana well, it is the federal government. Specifically the National Institute on drug apews. Which has traditionally only authorized the study of potential harm, not benefit. It is a choke point that prevents researchers from getting thegetting the marry want they need. Simply by with holding it, they are not able to conduct it. Laws are being made across the country, and yet the marijuana is incredibly limited. Yeah, we are seeing legal medical use and legal Recreational Use and yet there is no research looking at the actual risk, and therapeutic benefits of smoked marijuana. How do you account for this and how marijuana is treated. You have to look back at the history of marijuana which has been prohibited since the 1930s. The federal government at large has seen marijuana as the lynch pin of the war on drugs. As the drug that can be demonized in an effective way we can label it as a gate way drug even though theres no evidence suggesting that people who use marry want facing marijuana are then led to go on to other druggings. The stigma of pot kept constance from using it for years. She has a rare auto immune disorder. You feel like you have a problem. But driven by crippling joint pain, she went online and read about the potential benefits of oil. She started distilling it underground. He said to me, how come you are so much better, i started shaking, i was like he is going to thing i am weird. A stoner, he is going to discount everything i tell him from now on, so i stood there shaking and i told him. I said i am afraid to tell you, but i have been experimenting with making this high thc oil for myself, it is allowing me to it is allowing me to get through the day, it is changing my life. He said oh my god everybody here needs that. Today she says they are sells her oil to 125 client as year including stage four cancer patients. The cost of a three month treatment cycle is about 7,000. We are number one in the world in cannabis oil. This tiny little operation. To date, no Clinical Trials have been conducted on the effects of the miracle oil. The few doctors that do study worries that its benefits may be exaggerated. Personally, i believe that in the test tube, and in animal models there may be some effect of highly concentrated but it pains me as an oncology for 30 years to see amazing advances, in our ability to treat cancer to keep people alive when patients come to me with a curable malignancy saying they are going to treat it with cannabis oil. He is bun of the only physicians that has received prescription. He believes that it can ease pain but is not a cure. Most of the people i have cared for for it cures canner i would have a lot more survivors. It must be hard to see your patients give money for totally unproven therapies. Right, it is all anecdote, and it is not evidence. We need to do the research, but our hans are tied because ewith cant really study it. Jobbing the regulators in washington have a cool about actual Clinical Applications of this very powerful medicine. Are you heedful in the your career things will change. I use to say now in my lifetime but now i think i shouldnt shortchange my life, we have seen so much change in the past few years that maybe we are coming to a Tipping Point the pressure right now i think is greater than it has ever been. To allow this research to go forward. In march the government finally granted Burgess Group approval to study the effects of pot, it is the first time anyone has received federal permission to study the benefiting of smoking marijuana hof researchers are still waiting for the plants to be delivered. Over half of the american voting population believes that marijuana should be legalized. Not just for medical use but legal for Recreational Use and thats setting up an opportunity for the Obama Administration to step in, this wont require a vote or an act of congress, an executive email from president obama requiring the process so this is the dollar bill method, it is very handy if you dont know how to roll a joint. Aaron hind isnt waiting for hard science. Allky do is just shake my head and laugh at everybody trying to hold it back, when it is a beneficial drug. All that it could have negative long term consequences. If i didnt have pot as a coping mechanism if you took it away, i would have turned to alcohol i might have attorneyed to something harder i may have conflicted harm am i giving a little piece of my long term memory, or short term memory usage for evenness in my life . Definitely. Our science and Technology Correspondent joins us. There is no scientific reason that keeps that makes it difficult, more difficult to study marry want than other substances . Marijuana, though, has this unique restriction. One that has no deadline, it can stall research forever, and that is utterly unique to marijuana. So if the researchers had their way if they had access and ability to get the supplies what do they want to study . What do they want to find out . One thing that is so difficult, is doing any sort of large cohort, a big group of people using it on a long term basis right now the stigma of it make it impossible to ask anybody and get a truly honest response about how much they use how much they feel depend on it, what they do when they are on it, as a result, our sources for instance at the Veterans Affairs say that they would really love to be able to act veterans in particular who are prone to addiction for a long term sense of who it is they do. Right now you cant get an honest answer like you can about cholesterol, when you are are talking about the Long Term Health of a massive population. So if it is so difficult to know more about pot in terms of science, why are lawmakers so willing to legalize it . Well, that is the great question i mean certainly when you talk to policy makers and ask them what kinds of science have you used to undergird your decisions when i have spoken for instance to the writer of the initiative that legalized marijuana in
