cardrona Posted April 18, 2021 Report Share Posted April 18, 2021 (edited) Study: States with Medical Marijuana Laws Have Lower Traffic Fatality Rates 12/16In a study from The Orange County Crime Lab with nearly 5000 drivers suspected of driving under the influence of drugs there was no correlation of tests on psychomotor performance and THC blood concentrations.Much has been bandied about in the press and legislatures about a AAA report showing an increase in traffic fatalities in WA and CO post-legalization. What is not often reported is: • The number of fatal crashes in Washington increased only about 6%, from 401 to 429, between 2013 and 2014, according to FARS data. Note that 2013 had a low number of fatal crashes, “involving recent use of marijuana,” compared to 2012 (409) and 2011 (421). Colorado saw a 4% increase in fatal crashes involving marijuana between 2013 and 2014, according to FARS.• The AAA study acknowledges that the “recent” marijuana use detected in crash victims in Washington could have happened a week earlier, and that “the data available cannot be used to assess whether a given driver was actually impaired, and examination of fault in individual crashes was beyond the scope of this study.” The increase could simply have been a result of increased prevalence of use, or increased scrutiny. The presence of blood levels as low as 1 ng/ml, in passengers and in drivers not at fault, were enough to designate a fatal crash as involving marijuana.• The percentage of fatal crashes involving marijuana, or marijuana only, was quite low. Most fatal crashes also involved alcohol, and/or other drugs:According to the Washington Traffic Safety Commission, of 592 drivers involved in fatal crashes in 2013, 38 tested positive for cannabis. In the following year, of 619 deadly crashes, the number testing positive for cannabis jumped to 75. However, as Staci Hoff, Research Director for WTSC, explained:“Most of these drivers, these 75 drivers, also had alcohol or other drugs” in their systems. Over a five-year period, just 1.8 percent of fatal crashes involved drivers who tested positive only for cannabis.“So, in our study, we looked at all five years of date, 2010 to 2014,” Hoff continued, “and there were never 3,000 drivers involved in these fatal crashes during that time period. Only 56 of them had THC and only THC, nothing else.” • Impairment testing is the best answer and the only fair way to judge a driver. Testimony on the oral swab testing bill from law enforcement in California noted that DREs are expensive to train and deploy, but that the state would qualify for federal grants for that as-yet-unproven testing technology.AAA: Tests for driver impairment by marijuana flawed CBS News, 5/10/2016Read the AAA studyCalifornia Lawmakers Working to Jail Sober Drivers Collide with Science East Bay Express, 5/10/16Fed study: Booze impact greater than pot on driving CNN, June 25, 2015 Traffic fatalities are “near historic lows” in Colorado following legalization there in 2012.A recent NTHSA survey, the largest of its kind ever conducted, assessed whether marijuana use by drivers is associated with greater risk of crashes. The survey found that marijuana users are more likely to be involved in accidents, but that the increased risk may be due in part because marijuana users are more likely to be in groups at higher risk of crashes. In particular, marijuana users are more likely to be young men – a group already at high risk.February 26, 2015 – An important new study shows high blood levels of THC can persist days after smoking following heavy use. Levels above 5 ng/ml, the DUI threshold in WA state, were detected as long as 4 days after use. This ought to put the nail in the coffin of proposals to establish mandatory per se THC blood thresholds for DUI. Highway safety researchers would do well to retarget their efforts towards developing better impairment tests, rather than pursue chemical testing for DUI.Stoned drivers are a lot safer than drunk ones, new federal data show February 9, 2015 U.S.: No evidence marijuana leads to higher crash risk February 2015 NHSTA Study A 20-month survey of drivers in 2013 and 2014 found that drinking and driving dramatically raises the chance of a crash, but didn’t find evidence that marijuana use is statistically significant in raising crash rates. See the NHTSA study online December 19, 2014 – For the third consecutive year, Cal NORML was able to derail an ill-conceived “zero-tolerance” DUI bill that would have criminalized all drivers with detectable traces of THC in their system—a population that includes most daily users. NORML experts provided key expert testimony against the bill, and our e-list subscribers sent over 2,100 messages of opposition to legislators. Numerous accident studies have confirmed that marijuana is not a major risk factor in driving fatalities. In general, however, studies agree that the combination of alcohol and THC is particularly dangerous, if anything worse than “straight” drunken driving.Marijuana Arrests Steady, DUIs Decline in CA December 12, 2014Federal Report: Problems with Weed DUI December 08, 2014 NHTSA Official Affirms Little Is Known About Stoned Driving August 4, 2014Stoned Drivers: The Case Against Panic; Pot prohibitionists undermine their own warnings about legalization and car crashes.

cardrona Posted April 18, 2021 Report Share Posted April 18, 2021 These studies all have been done , suites us to share information in certain fields , but then each science community needs to do a new review!!!!, what garbage get on with it , alcohol will always have hirer rates , but yet it’s fully legal. 1 Quote Link to comment Share on other sites More sharing options...
usednuts Posted July 25, 2021 Report Share Posted July 25, 2021 Seems to be conflicting science with cannabis studies. See Lambert report uni of NSW Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
