Car crashes due to drunk driving grew only 9.4% during the same time period, although the raw numbers of alcohol-related accidents was in the thousands, not the hundreds as with cannabis.<strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/strong><\/p>\n<p>\u201cThe concern is that the increase in these rare but very severe traffic injuries are capturing broader trends of increasing cannabis-impaired driving over time and after legalization,\u201d said study author Dr. Daniel Myran, assistant professor of family medicine at the&nbsp;University of Ottawa.<\/p>\n<p><strong><em>Just after Canadian legalization in 2018, when marijuana stores and products were limited, researchers found a 94% increase in emergency room visits<\/em><\/strong>, Myran said. As commercialization increased and marijuana was more widely available, visits to the emergency room grew 233% compared to the period before recreational weed was legalized.<\/p>\n<p>\u201cThe main message of this very well-conducted study is not the absolute number of crashes, but the increased rates. Cannabis is also probably under-reported in car crashes, and so the absolute number might be way higher,\u201d said Dr. Marco Solmi, associate professor of psychiatry at the University of Ottawa and investigator&nbsp;at Ottawa Hospital Research Institute in Canada. He was not involved in the study.<\/p>\n<p><strong>Not Just a Canadian Problem<\/strong><\/p>\n<p>While the new study was specific to Canada, the problem is happening around the world in areas where recreational cannabis use is legal, according to a recent \u201cumbrella review\u201d of more than 100 clinical trials and meta-analyses on the&nbsp;<a href=\"https:\/\/www.cnn.com\/2023\/08\/30\/health\/marijuana-pros-and-cons-wellness\/index.html\" target=\"_blank\" rel=\"noopener\">pros and cons of marijuana.<\/a><\/p>\n<p>\u201cThe general perception of cannabis as a \u2018natural\u2019 harmless plant is probably misleading young subjects that end up consuming high THC products, with untoward events including car crashes,\u201d said Solmi, who coauthored the review, via email.<\/p>\n<p>THC stands for tetrahydrocannabinol, which is the part of the cannabis plant that produces a \u201chigh.\u201d<\/p>\n<p>\u201cIn addition to car crashes, persons using cannabis are at increased risk of poor cognitive performance \u2014 which might contribute to car crash and failing education \u2014 and a risk of mental disorders,\u201d Solmi &nbsp;said.<\/p>\n<p>Driving under the influence of alcohol has been on the decline in the United States, but the last&nbsp;<a href=\"https:\/\/govtribe.com\/opportunity\/federal-contract-opportunity\/national-roadside-survey-of-alcohol-and-drugged-driving-693jj922r000060\" target=\"_blank\" rel=\"noopener\">National Highway Traffic Safety Administration<\/a>&nbsp;report from 2014 found a 48% increase in drivers testing positive for marijuana.
