The study found kids in eighth and 10th grades in that state are more likely to use marijuana\u00a0since legalization and have shifted even more than the national trend toward thinking marijuana use doesn\u2019t pose a great or moderate health risk.<\/p>\n<p>\u201cOur study didn\u2019t particularly tell us why\u201d the two states differed, said Magdalena\u00a0Cerd\u00e1, a researcher at the University of California-Davis Violence Prevention Research Program and the lead author of the study.<\/p>\n<p>But she and her co-authors have a theory. When Colorado voters passed recreational legalization, the state already had a large medical marijuana industry with numerous dispensaries. In Washington, the industry was less developed \u2014 meaning its teens weren\u2019t as exposed as those in Colorado to marijuana ads and other commercialization.<\/p>\n<p>Cerd\u00e1\u2019s study is the latest to try to make sense of legalization\u2019s impacts in Colorado.<\/p>\n<p>To conduct their research,\u00a0Cerd\u00e1 and her colleagues dug into raw data from the University of Michigan\u2019s national Monitoring the Future survey.<\/p>\n<p>A different national survey, by the federal government, this year estimated that the percent of kids ages 12 to 17 in Colorado who used marijuana in the past month <a href=\"http:\/\/samhda.s3-us-gov-west-1.amazonaws.com\/s3fs-public\/field-uploads\/2k15StateFiles\/NSDUHsaePercents2015.pdf\">was the highest in the country<\/a>. But that same survey concluded the rate <a href=\"http:\/\/samhda.s3-us-gov-west-1.amazonaws.com\/s3fs-public\/field-uploads\/2k15StateFiles\/NSDUHsaeShortTermCHG2015.htm\">was flat since recreational marijuana stores opened<\/a> \u2014 something <a href=\"http:\/\/www.denverpost.com\/2016\/06\/20\/marijuana-use-colorado-teens-marijuana-no-increase\/\">echoed this year<\/a> by the state Health Department\u2019s <a href=\"https:\/\/www.colorado.gov\/pacific\/cdphe\/hkcs\">Healthy Kids Colorado Survey<\/a>. The percentage of Colorado kids who reported using marijuana in the previous year <a href=\"https:\/\/www.washingtonpost.com\/news\/wonk\/wp\/2016\/12\/21\/one-of-the-greatest-fears-about-legalizing-marijuana-has-so-far-failed-to-happen\/?utm_term=.85a93160676e\">actually declined<\/a> in the federal government\u2019s survey this year.<\/p>\n<p>The state\u2019s long-term trends, though, point toward higher marijuana use and <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/24837585\">lower perceptions of risk for Colorado\u2019s youth<\/a>. A decade ago, the federal government estimated that about\u00a07.6 percent of kids ages 12 to 17 in Colorado used marijuana in the prior month. In the survey results released this year, that rate had grown to about 11.1 percent.<\/p>\n<p>Cerd\u00e1 said it will take more study to determine whether changes in the state\u2019s marijuana laws are the cause of that trend.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Recreational marijuana legalization had no impact on how many Colorado teens use pot or on whether they think it is dangerous, but that could be because years of medical marijuana sales had already brought about changes in those measures, according to a new study. <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[6811,6911,6892,6813,77,6815,5667,56,9,5019,1,3,61,1736],"tags":[6816,6912,6893,6818,2655,6820,5673,2636,5022],"_links":{"self":[{"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/posts\/7079"}],"collection":[{"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/comments?post=7079"}],"version-history":[{"count":0,"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/posts\/7079\/revisions"}],"wp:attachment":[{"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/media?parent=7079"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/categories?post=7079"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cannitrol.com\/blog\/wp-json\/wp\/v2\/tags?post=7079"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
