first president to visit cuba since calvin coolidge did it 88 years ago. president obama lands in havana. and alarming rate of rising drug addiction. the worst crisis in decades. and, the most unique boy scout troupe in america. all of its members are refugees. we begin with more passion from protesters on the campaign trail today. demonstrators briefly shutting down a highway leading to a rally held by republican front runner donald trump. and in new york city, today, hundreds took to the streets to declare their disdain for what they call hateful racist messages from the likely republican nominee for president. donald trump gets closer to clinching the republican party nomination, the antitrump movement across the country is also gaining steam. in new york city saturday, about a thousand antitrump demonstrators master planned from central park to a rally in midtown. >> we don't want donald trump as a candidate for the election in this country. we don't want him. he isn't republican, conservative, independent, anything. >> meanwhile in arizona does dos of demonstrators blocked a highway. maricopa county sheriff joe arpaio. >> some demonstrators were trying to disrupt -- disrupt because of them, you had to get a little more sunshine, but we made it. and three of them are in jail. >> they blocked the road. they chained themselves to the cars. there were about 50 of them. but listen to this: what sheriff joe did, he said get up get out, they didn't. they cut the chains, it took like two minutes. they cut the chains. they arrested three people. and everybody else left! right? >> the tension that has marked trump rallies in recent weeks continued on friday in salt lake city, when the demonstrators tried to bream the facility's doors. trump was unphased. >> they don't show the 2,000 people that are trying to get in that are with us. >> meanwhile, the new york times reports that members of the republican establishment are trying to pull together a 100-day plan to deny trump gop nomination. the 2012 nominee mitt romney, who actively campaigned for john kasich in ohio, concluded that ted cruz is the best candidate not trump. so he will vote for trufs e-cruz ited cruz forthe utah primary. >> if we vote for donald trump, hillary wins. >> and trump continues to lead in the polls. okay let's take a look now at where the rest of the presidential candidates are today. the republicans first, senator ted cruz spending the day in utah, so is governor john kasich. there is a very limited schedule for democrats. bernie sanders in arizona. hillary clinton, no public events scheduled. senator cruz is as we mentioned in utah ahead of tuesday's republican primary in that state. he was on the offensive telling voters in provo this afternoon that donald trump has supported liberal democrats for years. >> donald continued, he said ted when it comes to the supreme court, when it comes to religious liberty, you have got to learn to compromise. you got to learn to cut deals with the democrats and go along to get along. well let me be very, very clear to the men and women of utah. i will not compromise away your religious liberty. >> all right in utah today, republican candidate john kasich telling the be voters, he says the programs should reflect local values. >> my value, my philosophy on welfare is what my mother taught me. it's a sin not to help somebody who needs help. but it is equally a sin to continue to help somebody who needs to learn to help themselves, okay? >> for democrats, senator bernie sanders traveling to washington state to campaign there and on the way he stopped in arizona, without naming him took aim at donald trump. >> what is not fine is when you have candidates for president and other people who are spewing out hatred and bigotry against mexicans -- >> booing ] >> that is not acceptable. >> hillary clinton had very little scheduled today. but both she and former president and her husband bill clinton will be in arizona on sunday appealing for votes in tuesday's primary there, the state's largest paper the arizona republic has endorsed ms. clinton. here's what's next on the primary schedule. three races on tuesday. for the republicans it is win are take all in arizona, 58 delegates at stake. there's also a primary in utah. 40 delegates up for grabs there a total of 98 delegates for the gop. for democrats, two primaries and a caucus. 85 delegates available in arizona's primary for the democrats, utah it's 37, idaho holding a caucus, 27 delegates in utah, in those states, for the democrats, president obama will become the second is iting u.s. president to visit cuba. calvin coolidge was the first and only one to so so in 1928. al jazeera's melissa chan is there for us. melissa how are cubans reacting to the upcoming visit? >> you can imagine how excited everyone in cuba is. this is an historic visit. and one thing is they have been a bit cynical about this visit as well. they love president obama, he's the one that broke the status quo and brought normalization to the forefront along with raul castro. the potholes are getting fixed, some of the infrastructure has been getting fixed that has not been addressed for a very long time so the president also bringing a little bit of good luck in terms of the city getting specifiegetting spiffed. this is a very intense time for the city. the tampa bay rays against the cuban national team. and a concert, they expect half a million people at that concert randall. >> we learned a little bit more about the president's itinerary. where will he be going? >> reporter: in terms of the president's itinerary, it's -- he's got a packed schedule for monday and tuesday. he arrives on sunday evening. he's going to meet the embassy staff, possibly walk around the city, old part of the city. but his official state visit doesn't actually start until monday morning at which point he is going to visit the jose martin monument. he is not going to meet fidel castro, after raul castro and president obama meet they are going to have a bilateral press briefing and later on in the afternoon we also understand something very important for president, president obama is going to attend a discussion of entrepreneurs about entrepreneurship with americans, cuban americans and cubans participating and he tops off monday night with a state dinner, randall. >> so melissa we mo know this triknow this trimis carrying wip the carrying with it a fair amount of controversy. what do you know about that? >> the embargo being in place for so many decades after all. here in cuba based on one poll, one of the very, very few polls we would get from this country, washington post and eun vision n polls, calling this visit a disgrace, that the americans have conceded too much over the past year, in terms of moving this process of normalization and not getting enough back from the cubans in terms of assurances, on human rights violations. very much like the united states has be a situation with china, continues to do business with china, that is concern for people looking at the u.s.-cuba relationship and what it might look like in the future randall. >> not only human rights issues, in china for example. thank you melissa. suicide bomb are killed himself, dozens more were wounded, in istanbul. this comes on the heels of

year there have been several bomb attacks across the country. three alone in the capital ankara. in total they've killed almost 300 people. the most recent was less than a week ago. the tak or kurdish freedom hopes group which is linked to the pkk claimed responsibility for that attack which also targeted a busy shopping street. days later germany announced it was closing its consulate in istanbul siting credible information that another are terroristerrorism attack was im. increased number of attacks could threaten its economy. for now, the government insists turkey is safe. but all have to do a lot more if it's to ensure the safety of its citizens and visitors. jamal al shael, al jazeera. >> flit we have new details about the major suspect in last year'year's attacks in paris. investigators say salah be abdeslaabdeslamwas planning to e suicide bombers but backed out. jacky rowland with more. from brussels. >> reporter: a police convoy carrying salah abdeslam arrive at

of the european arrest warrant i can tell you that we refused extradition. >> reporter: the french authorities have now issued a new european unio european be at against salah abdeslam. >> translator: in our investigation it has become even more true that he is a key player in the paris and st. denis attacks. our investigation shows he played a key role in the logistical preparation of the attacks and him being present on the 13th of november. >> there is still tension in the mollenbeck neighborhood. four other people were arrested at the same time as abdeslam. a family suspected of sheltering him during his time as a fugitive. >> this is his system neighborhood, no be doubt he has friends and neighbors who are willing to shelter him. >> translator: we are very, very relieved and happy that we stopped this not only for europe but the rest of the world. >> reporter: it was this raid earlier in the week in a flat in a different part of brussels that gave police clues on the whereabouts to the most wanted man in europe. a phone call made with someone linked to abdeslam. salah abdeslam had been on the move for more than four months. friends pick him up and brought him to brussels. since then it would appear that his movements were limited to an area of just a few kilometers as he ran out of options and hiding places. 130 people were killed and more than 300 injured in coordinated attacks on cafes, a concert hall and a football stadium in paris on november the 13th. the main surviving suspect links to those attacks is now under arrest. authorities in france and belgium have made it clear the investigation is far from over and other arrests are expected. jacky rowland, al jazeera, mollenbeck. >> the worst drug crisis in decades. >> i saw 20-year-olds come in with habits of oxycontin. >> a deep look at the nation's prescription painkiller epidemic. and later, the worldwide celebration of earth hour. a call to protect the environment. >> the centers for disease control and prevention are taking aim at the country's worst drug crisis in decades. experts say began not in the streets but in doctors offices all around america. tonight we take a deeper look at the prescription drug epidemic in the united states, patients suffering from chronic pain want treatments had will work quickly. a prescription for opioids such as vicodin or oxycontin can help patients get back on their feet but long term use is not as effective as one believed, instead they are apparently a gateway to addiction. as al jazeera's erica pitzi reports, it is a prescription that reverses decades old practices. >> reporter: the centers for disease control and prevention has put its foot down. announcing new guidelines to curb drug abuse. >> the goal of the new guideline is to help providers improve patient care and safety and prevent opioid overdose. >> the drugs in question are opioid pain medications like vicodin and oxycontin. to give most patients only enough pills for a few days. the cdc hopes the new standards will save lives. its director thomas freeden spoke to be journalists on a conference call. >> effect on american lives families and communities means we have to act now. >> reporter: 2014 set a record for deaths related to opioid abuse with more than 28,000 people dying of medical overdoses. the medical community has been distressed by the link between opioid painkillers and heroin. many people addicted to painkillers turn to the drug, a less expensive high. the national institute on drug abuse finds that over 75% of heroin abusers in the 2000s started out using prescription painkillers. we talked to deb richter in vermont where the problem is especially severe. >> in early 2000, 2001 i started to see a bunch of 20-year-olds come in with the habits of oxycontin. to me it started out with pills. >> opioids are frequently prescribed for chronic pain problems like back pain and arthritis. nearly 250,000 prescriptions are written every year with annual sales of millions of dollars. short term use by patients recovering from surgery or terminally ill patients. but in the 1990s drug companies began aggressively be be be attacking the problem. >> see what it's like when you are not in pain anymore. take these medications. >> many doctors were happy to offer their patients the ability to pop a pill to alleviate suffering. but critica pleading guilty to l charges by one drug company, prescription painkillers the best solution for chronic conditions. >> but we don't have evidence to show that opioids can controlling chronic pain effectively over the long term and we do have evidence that other treatments such as exercise therapy, nonsteroidal antiinflammatory drugs and a variety of treatments and modalities, can be spheive. feive. feive. affective. >> to stop the prescription drug epidemic in its tracks. be erica pitzi al jazeera. >> joining me is andrew cologne, and from stanford, dr. anna lemke, dr. colodne to you in the studio sir, secluding cancer patients and palliative care who should receive opioids and for how long? >> opioids are medicines that are essential for end much life care and a few days after major surgery, for example. the reason the cdc is issuing this strong recommendation is because they are concerned that doctors in the united states are overprescribing opioids for common conditions. the practice of treating low back pain and chronic headache, fibromyalgia, with long term opioids, has become widespread. and what the cdc is saying is we are harming far more patients than we're helping and we're fueling epidemic of addiction and overdose death. >> to you dr. lemke, opioids have been around for years. what triggered the explosion in use and the resultant addiction? >> well, starting in about 1980, there was a huge push to use opioids more liberally in the treatment of pain and it came out of a well-intentioned place. there were a lot of people struggling with severe pain and end of life pain and they weren't getting the compassionate occasion that they needed. there was a big push to help patients in pain. the idea was if we used opioids more liberally we could help individuals suffer less. unfortunately that slowly morphed into using opioids for very common conditions. self-limiting conditions. till it got to the point where doctors began prescribing opioids the way they would prescribe tylenol or aspirin. >> why were they doing this? were they getting paid extra 50 pharmaceutical companies for example? >> yes, that's a good question. i believe most dorkz are well dl intentioned and want to help people. doctors were convinced by thought leaders in the country that be opioids were safe. pseudo scientists were supported 50 pharmaceutical industry. but -- supported by the pharmaceutical industry. that individual has len less than 1% chance of getting addicted. that turned out not to be true but it was as if doctors were told that there was some kind of magic halo effect as long as they were prescribing the opioid then the patient wouldn't get addicted. doctors believed it because they went to academic meetings, very formal kind of academic settings and they were told that this is science so that's what -- uh-huh. >> dr. colodne is nodding with your answer. >> yes so as dr. lemke was saying, in the 1980s doctors began to get encouraged to use opioids more frequently and we were told this was the compassionate way to treat many different complaints of pain. but it was in 1996 when purdue pharma introduced a new opioid called oxycontin which is an extended release version of oxycodone. when they release they'd drug they began a campaign with millions of dollars invested in changing the way doctors think about opioids. and that's when we started to hear the risk of opioids addiction, was exaggerated. it wasn't from the drug companies, doctors eminent in the field of medicine were paid by the companies to give those lectures. >> where was the food and drug administration in this issue? >> good question. if the food and drug administration had been around when that drug was introduced, they would are have told, send yourself first to the hospices and the oncologists. had they done that, had they told purdue pharma that you can't market the drug to the be authorities then we wouldn't have the trouble today. >> they had the authority to can that did they not? >> if they were appropriately enforcing federal law that's exactly what they would have done. in part they were swayed by the same campaign that was swaying the rest of the medical community but also there has been a very cozy relationship between the reergt regulators ae fda and the same official who approved oxycontin ended up working for company that made oxycontin. >> did this happen? >> yes, it did. >> addiction specialists at the veterans administration know that patients can be addicted to medications that they get there and some have begun pushing for a new tool to stop overdose deaths. al jazeera's jake waral jazeera. >> this veteran says he has been addicted to heroin and prescription opioids for most of his life. and for boston like so many veterans heroin and prescription opiates offer the same risk of death from overdose. that's where the be veterans administration has a massive problem. 50% of its patients seek opiates for pain. developing a program that would give any veteran at risk of abusing opiates and perhaps all veterans who are prescribed opiate medication another medication as well, narcan or moloxone. >> if every single one of them needs to go to a multidisciplinary pain clinic that's a lot of pain care you need to provide. >> reporter: for the vast number, the va has not been able to cut the overdoses and nar scan sort of a last ditch crisis management tool. >> people think of this like an epid pen. epipen. >> the drug that comes from the va can sometimes lead people into heroin. >> yes but that certainly doesn't reduce our -- you know, our need to protect people. >> for boston, a nationwide narcan program can't arrive fast enough. >> i've lost a lot of friends to overdoses. and they weren't -- some of them were the biggest addicts i had ever complete in my life. but they were also fathers and brothers and sons and the best friends of my leave. and to lose them because the government hasn't come around yet it's ridiculous. >> be jacob ward, al jazeera, san francisco. >> let's focus on you dr. lemke. what do you say to patients who say, look, opioids help me to live a better life. is there an alternative for them? >> what i say to them is, firm i validate that they have pain, and that we would not want to ignore treating their pain. but what i let them know is that new information has come to light such that we know there are now risks with chronic opioid use that we hadn't realized before. obviously one of the risks we talked about is the risk of death. but the other risk is that the body adapts to the presence of the opioid such that it stops working and in fact people can develop hyperalgesia, hypersensitive to pain. it could be, you feel like this opioid is the only thing ahelps with your pain but it may indeed be harming you more than it's helping you and that's a very important message for people to hear. >> apology to you, while were talking on that point, we were showing a picture of people shooting up with hoirn. dr. cologne, in your professional opinion would a lessening of opioid prescriptions lead to lesser heroin addiction? >> no, it's the vaim addiction, opioid addiction. i think what you're asking is would more people switch to heroin. >> if they can't get the prescription drug. >> yeah, it's a really good question. i think the answer to the millions of americans who have been put on opioids and those opioids aren't working well for them, i don't know that we can immediately strip their opioids away from them that could lead some to turn to heroin. the answer for the millions of americans who are addicted who might be switching from painkillers to heroin already is see if we have better access to effective addiction treatment. there's one very effective medicine for treating opioid addiction called bupomorphine and we don't have access to that particular medicine. the answer is to see that more people who are addicted can access effective treatment. >> let's get the access to opposoid addiction issue. is there an alternative that is as cost-effective and that will be covered by insurance? for example, pain management? >> well, opioids are certainly not cost-effective. i suppose it's less expensive initially for an insurance company for a doctor to just write a prescription, than for a patient to receive other therapies or the their treatment. but it's penny wise and pound foolish because the patients wind up often unable to go back to work. the patients wind up on higher and higher doses. their function begins odecline. and they can done addiction. many patients on long term opioids become addicted to them and that's a very expensive problem to treat. >> dr. lemke, the guidelines from the cdc are suggestions. they are not regulatory requirements. to what extent do you think doctors will follow this recommendation and to what extent do you think states should move from the guideline to make it a law in terms of you 0 doctors prescribe opioids? >> well, i think the cdc guidelines, because it's the cdc and it's a federal organization that carries so much influence, i think these guidelines issued from the cdc will have a huge impact on the culture. and that doctors will in fact change the standard of care. i think like it's already happening. the implementation, though, of the guidelines in real life has several important obstacles. a lot of the patients that primary care doctors get are inherited patients. they come to them already on high doses. so it's not a matter of telling primary care doctors don't start the patient on opioids. it is a matter of starting those primary care doctors to get their patients off of opioids which is a long and arduous process. another thing you raised randall about insurance companies. it's easy to say use some nonopioid alternative. but in a lot of rural areas patients don't have access to physical therapy and mindness meditation. and insurance companies won't pay for it randall. >> thank you, for taking a deeper look. >> thanks for having me. >> you're welcome. >> up next: a majority development in the war in syria. an option group sets up a new federal session, the kurds declaring be automatically in the north. and, some of the worst flooding in decades. >> our american story is written everyday. it's not always pretty, but it's real... and we show you like no-one else can. this is our american story. this is america tonight. >> dozens of people are dead in the northern syrian town of raqqa, after air strikes hit it today. initial reports point to syrian or russian planes being on the air strikes. coming on the heels of the announcement by russia of pulling back their forces. syrian kurds have declared a federal region in the northern part of the country. split between iraq, syria and turkey but have never had their own recognized country. the declaration was met with immediate opposition. >> translator: for us, we totally oppose it. syrian people with free will are the future of this country. the only constructors of government. >> other groups have come out strongly against the kurds' move including turkey and the syrian regime. joining us now is ambassador peter galbraith. he is the former advisor to kurdistan regional government. first of all what do you make sir of this announcement today, what i suppose it amounts to a declaration of independence. >> oh, not at all. the syrian kurds have declared a federal region which is meant to be part of syria. they're hoping that in the peace talks that are now underway which will involve a new constitution for syria that the country will have a federal model. and that their region will be part of it. or failing that, that at least they would be a special case where they would be allowed to run their own affairs. but the syrian kurds are very clear that they are not interested in the breakup of syria so they're really in a different place than the iraqi kurds who do have a kurdistan region and who are moving towards independence in the near future. >> what is america's position on the move by the kurds in syria? >> well, the state department today said that they were opposed to it. but the reality is that the syrian kurds are america's closest ally in syria, in fact america's only ally in syria. they are the only effective fighters against the islamic state, in fact they have basically pushed the islamic state quite far back from where it was two years ago. they are breaking the link between raqqa, the capital of the islamic state and most mosul to the east and turkey to the west. so they're really key to the strategy of degrading surrounding the islamic state and ultimately defeating it. that said, the americans therefore, while they've taken this formal position primarily to please turkey, in fact they are not at all upsaid that the syrian kurds have clair declarea federal region and many people in fact i believer supportive. >> turkey has been long concerned you said about the cuferredkurds in its country jog with the kurds of iraq to form a greater country. can you understand why turkey would be anxious about this declaration? >> turkey's position on the kurds is quite complex. turkey is supporting the independence of the be independence of iraqi kurdistan. allowing iraqi kurdistan to export its oil essential for its economy. in the case of syria, the turkish government sees the syrian kurds as linked to the pkk which is the turkish kurds who are fighting against the turkish state. but turkey doesn't really have any options. in fact, by putting pressure on the syrian kurds not maintaining good relations, it really is forcing them into the arms of the russians and to make a deal with the regime. if that happened, that would be the end for the groups in syria that turkey last been supporting. so turkey has a stand, but it doesn't -- but it's a policy in fact that really isn't working. >> and one last question, ambassador. what do you make of this announcement in context of the talks in brussels that are supposed to lead to total ceasefire and eventually a political solution? >> well, that's a very important question. the syrian kurds already had set unthree cantons, self governing region. why did they go ahead and announce a single federal region? the fact is they have been comploouted from the peaccomplo. if i don't have a seat at the table you create facts on the ground that is going to make people have to pay attention to you. by creating a federal region they're making the world pay attention just as we're having this discussion right now. >> ambassador peter galbraith, thank you very much for joining us and sharing your insight into the syrian crisis and the kurds. up next, the world celebrates earth hour. >> three two one! >> it is an international call to protect the environment. plus: it could be the most unique boy scout troupe in america. all of its members are refugees. >> and i'm meteorologist nicole mitchell. mother nature may be confused. spring is just a few hours away, but there is flow and below freezing. i'll have that forecast. >> it is a worldwide movement to acknowledge the destination of climate change. >> three two one! >> in pakistan, hundreds gather to shut the lights off and light candles at night for one hour. it is the country's effort to show their commitment to saving the planet, earth hour is celebrated to raise awareness of global issues plagued by environmental pollution. and in italy, the lights went off at the coliseum in rome and many other iconic monuments as that country urged residents to turn off nonessential lights. earth hour is the most important movement to raise climate awareness. >> right here in the united states, times square dims their lights for an hour. nicole mitchell is here, no dimming of the lights in the newsroom, that wouldn't do well for our telecast. >> try and do that and conserve as much as possible. as we head out the door today, we had this system, part of it moved through south, this was expected. it added to the flood places we already had from heavy rain into last week so places like texas that kind of added to the flooding that we already had. this is continued to clear out though for south but it is now causing us more problems along the atlantic. we have all these areas that need to dry out, definitely needing a couple-day break which it looks like we'll get. you can see the moisture in the northern edge of this starting to get cold enough in the evening hours that more of this is changing to snow. as this develops along the coastline there could be more of this tomorrow. there are just a couple of showers but that clears out pretty quickly through the southern tier but mostly the mid atlantic and the southeast that we will see tomorrow. a lot of this may not be until later in the day but you can see especially close to the coastline or places like the east part of long island, the eastern part of massachusetts or jetting into the ocean a little bit more those are places that could get some of our heavier snow and a lot of this clears out as we get into the day on monday. but in the meantime we will be looking at couple of places with heavier snow. higher elevations of the appalachains, and a couple of places getting six inches or more for the first day of spring that's not what a lot of people want to hear. colder air around this, tomorrow 50s as far south as memphis but overnight tomorrow into monday morning, we have freeze warnings even in portions of texas. temperatures below freezing this late in the season that's significant. >> hopefully snow won't be here for long. thank you nicole. for more than 100 years, the boy scouts of america happening to an institution. helping to mold boys into men. a diverse troop in colorado, made up of refugees. >> troop 1352 is like any other boy scout troop. they cook their food and they are awarded merit bangs badges for a job well done. >> we come to camping and activity, one would come back they give us badges. >> that's so beautiful. is that special to you? >> yeah. >> but out of 38,000 boy scout troops around the world, colorado's troop 1532 is different. this band of boys is made up entirely of refugees.
