part of america's foreign policy. north korea test fired mies into the waters off the east coast today. the six such tests in the last month. the u.s. state department called on north korea to stop further tests calling them quote provocative actions that aggravate tensions. it's believed north koreans are testing in response to joint military exercises u.s. is conducting with south korea. in england prosecutors say they'll charge doctor and his assistant for vie lithing the law banning female mutilation. the law went into effect 30 years ago. if kwoikted the accused could be sentenced to 15 years in prison. charges five months after the reveal of procedures performed tens of thousands of times since it wasanned in the uk.

the two will play tomorrow before returning home. for more about malaysia airlines flight 370 we're joined from los angeles by andy. you were on a couple of nights ago speaking about debris australians spotted. today we hear the chinese have spotted debris. are we likely to see this repeat over and over again? it's a big ocean. >> it is a big ocean. we might see more of it. it's not clear if either of the pieces of debris matter. you're starting to see intriguing conflict between the extremes of nature, extremes of technology. the nooi which you are part is this is a forbidding part of the world. huge waves, constant winds, white caps everywhere,hard to

spot 60 or 70 foot long piece of debris. on the other hand you have extremes of technology. countries using their super secret resolution imaging satellite to see what they can find. you have sometimes a gap between the time the image is spotted. some person or persons e ball it to make sure it merits further investigation. when the planes go to find it, it may not be there because of extreme weather or sunk. >> what about the idea different systems are working together. is the quality of imagery the same? >> from the outside it's hard to tell how well they're working together. australians have been talking about the need for assistance from experts to look at imaging and countries to work closer together. i think they're trying.

it's not clear it's working so well. of course these are really very special assets for every country. they don't want to divulge publicly or to other partners in the search exactly what they have. and the resolution or the quality of the images varies of course depending on the system. in the case of the u.s., we're using partly commercial satellite imaging company, digital globe. their imaging is absolutely as good as using certain satellites and certain instances as good as any national imaging stem. >> there are reports the pentagon spent $2.5 million on this. what type of assistance might the defense department be giving in thesearch? >> i would say $2.5 million is a tiny portion of how much we've actually spent. if we task satellites, instruct

them to look at certain areas, it means they're not looking at other areas. we use expertise to look at these. we spend more than that. what the malaysians asked for and u.s. is likely to give some, versible tiny robotic marines to go under the ocean and see what they can find. thooifr asked for underwater listening devices. as well as tankers which are much harder. many of these planes can't be refuel in midair. >> if we look at the air france disaster, it took two years to agree on where to go back and search. it was in the area they previously searched. my question is, are they tooiak precautions before they check off the box of the area of the plane? >> they have learned a lot, experts have, from previous

searches. it's not quite as deep as it was in the air france crash. weather is very bad. every day that goes by, itfalls in that portion of the world. every day that goes by, it's a bigger challenge. mother nature is really fighting our technology. >> all right. andy passer from the wall street journal, thanks so much. >> you're welcome. and now to our signature segment, our original reports from around the nation and around the world. our focus tonight, marijuana use and marijuana laws. colorado and washington have already legalized the sale of recreational marijuana and other states are considering following their lead next your. what might the dramatic shift mean for drug use and abuse in the united states? to find out we recently traveled

to the netherlands which has allowed the sale for 40 years. when you first visit amsterdam famous coffee shops -- that's what all marijuana shops are called. the thing you notice is how normal it seems. it's not like a starbucks in the u.s. people, mostly foreign tourists, sitting around sipping coffee and openly smoking marijuana they bought in the shop. what could get you arrested in most ameran cities here is just fine. >> americans love potent weed. >> michael owns and runs two coffee shops in amsterdam. he was one of the original entrepreneurs in the 70s when they began allowing the sale of cannabis. >> this has been going on 40 years. nobody gives a [ bleep ]. it hasn't brought the country down. what's the fuss about? >> you might think buying,

selling, smoking small amounts is perfectly legal. well, it's not. tolerance is the key word here. the government tolerates these activities. you won't be arrested or fined or hassled. the government licenses coffee shops to sell marijuana as long as they follow the strict rules. no one under 18 allowed to buy or step foot in the door. zbl there's no advertising. no alcohol or hard drugs alowed. customers can buy five grams at a time that's about hhalf a cup. in colorado and washington there will be no on site smoking. if the united states is heading down the road of allowing it, what's the potential harm? >> people using cannabis use less alcohol. >> he is the lead researcher at the top government research

group on mental health and addiction. he's been evaluating the effects of different drugs. >> what about the arguments many in the u.s. feels when the government does step forward and say we're going to allow the sale of cannabis for recreational use thats that a terrible message to young people? >> it's a less terrible message than to say we keep alcohol legal and tobacco legal. alcohol and tobacco cause in the long run irreversible health damage. brain damage, liver, lung damage. cannabis, we don't have overdoeove overdoses, cirrhosis. >> imagine can be damaging. 9% of people that use it they will become addicted. it can be harmful to kids,

pregnant women and those with mental illness. two of the other big public health fears about loosening marijuana laws haven't come to pass. according to data, the coffee shops haven't caused the rise of other drugs like cocaine or heroin. many argue marijua users move on to harder drugs. second, dutch policy hasn't turned the dutch into a nation of pot heads. 6% of people in the netherlands report using marijuana compared to 9% spain, 15% in this u.s. >> in the netherlands, if it comes to prevalence in the population, we are not the highest. france is much higher. spain is much higher. >> places that have no coffee shops? >> and fully repressive on the user. spain is changing now, but france has been very repressive.

you have higher prevalence than here. making it easily accessible doesn't mean you get high prevalence. >> it's not clear the americans use will match netherlands. the two are so different in many ways, size, demographics. there are dutch serious problems that prompted the debate among citizens and politicians a like in the netherlands about how the coffee shop system should evolve. here's one example. even though you're allowed to walk in and bye pot, no one is allowed to grow large amounts or sell pot to the coffee shops. listen to the coffee shop owner describe this. >> you have a men you people can mike a selection from the variety of things you sell. where do you get that from? >> i don't know. that's the great mystery. >> you make up and there's a

magical supply that appears? >> magically. i do not have suppliers. >> dutch say they intended to address this gap in the law which exists when coffee shops were introduced in the 1970s. there was such widespread criticism that the dutch say they were pressured to not go further and regulate the supply chain as well. >> the person who magically delivers your supply to your shop, he's breaking the law? >> oh definitely. >> if he's arrested, he'll go to jail. >> i started as a grower. >> he put us in touch with his supplier that agreed to talk as long as we didn't reveal his identity or use his real voice. he imports some of his marijuana from a broad, but much of it is grown in the netherlands by a housewives and a like.s, >> are you worried even though this is a fairly tolerant

society that you might be prosecuted for what you do? >> that's a possible. yes,everyday. >> everyday. doesn't that get stressful after a while? >> no. you just use to it. >> the decision not to regulate the supply chain causes several problems. not only do they lose the chance to tax that side of the business. more importantly it's allowed in legal export markets to flourish. 80% of the pot grown in the netherlands gets sent a broad and ends up on the black market. another official said quote we are a supplier of drugs for the rest of europe. we never intended to become a major exporter of cannabis to the rest of the world. officials in ten cities have appealed to the government to fix this gap in the law, but nothing has happened. back in the u.s., colorado and washington are regulating their entire pot market. how it's grown, processed, sold, taxed. their rules were designed to

protect consumers and insure none of the legal pot ends up on the illegal market. the irony here is that the u.s. has two states implementing more comprehensive policies than the dutch ever have. >> back in the netheands, dutch have continued to refine their policy. they stepped and forced coffee shops this. in the 90s there was concern about too much leeleniency. the dutch are legalizing the potency of pot. something washington and colorado want to do as well. dutch scientists test coffee shop marijuana. anything over a certain level is considered hard drug and forbidden for sale. the dutch have also had a national debate about whether drug tourism needs to be reigned in. in the small city that sits on

the border of belgium and germany, an alarming number of visitors crossed into th town with one destination in town mayor of the city -- >> we had 2 million foreign visitors at the coffee shops. you can say that's of course good for the economy because when they're here o they spend money to other things. those that don't go to shops or hotels and restaurant, enter the country, buy it, smoke it in the shop, in the car go back to the shop for a second and then go back home. >> for a ci of 120,000 residents and one who's streets were laid out in the middle ages, 2 million visitors caused a headache for local residents. otherorder town mayors voiced similar complaints. two years ago, new national rules went into effect banning anyone who's not a legal dutch resident from buying in the coffeeshops. no more tourists allowed.

the new rules exposed the city. amsterdam said it would never deny the sell to tourists. other mostly southern border towns welcomed the ban and did comply. subsequently, six of the 14 coffee shops closed down. some for breaking the rules and selling to rists. several said they didn't have enough customers anymore. by all accounts, the streets are much quieter now. there was a down side. street drug sales spiked. >> i'm satisfied with the fact foreign people are not welcome anymore. we need a certain period, a new balance. it's much safer and healthier in the city now. much more place for the citizens to develop in the economic way. >> for hipart, amsterdam

coffee shop hopes the u.s. doesn't continue the rapid path toward legalization. he's worry had the might encourage other countries including his to follow suit. he says the legal patch work system serves to keep the price of pot high and number of competing coffee shops low. this one business man does not want to see change. >> i'm fearing american policy makers because when cannabis is legalized in this country, i lose my business. >> why is that? >> it's a legal product so margins and everything will change. >> if everyone can sell it, prices go down. your profits go down? >> of course. >> economics. >> simple economics. >> see how marijuana laws are changing across the united states. visit news hour.pbs.org this is
