Marijuana significantly impairs judgment, motor coordination, and reaction time, and studies have found a direct relationship between blood THC concentration and impaired driving ability.
Marijuana is the illicit drug most frequently found in the blood of drivers who have been involved in vehicle crashes, including fatal ones. Two large European studies found that drivers with THC in their blood were roughly twice as likely to be culpable for a fatal crash than drivers who had not used drugs or alcohol. Those involved in vehicle crashes with THC in their blood, particularly higher levels, are three to seven times more likely to be responsible for the incident than drivers who had not used drugs or alcohol. The risk associated with marijuana in combination with alcohol appears to be greater than that for either drug by itself.
Several meta-analyses of multiple studies found that the risk of being involved in a crash significantly increased after marijuana use—in a few cases, the risk doubled or more than doubled.
Evidence shows a substantial increase in drugged-driving deaths as
opiate use soars and marijuana has become legal..
In random roadside testing, more than 22% of drivers showed evidence of drug use, according to NHTSA data.
U.S. transportation safety officials are sounding the alarm on drug-impaired driving, calling for state and federal regulators to do more to tackle the growing problem as states grapple with prescription drug abuse and adopt a more permissive stance on marijuana.
The National Transportation Safety Board (NTSB) on Tuesday called on the National Highway Traffic Safety Administration (NHTSA) to write standards for devices allowing police to test drivers for drugs on the roadside and to give states additional guidance on how to combat drug-impaired driving.
Pickup driver high on weed & anti-anxiety pills killed 13
The recommendations came out of the NTSB’s investigation of the 2017 crash in rural Texas that killed 13. The accident was caused by a pickup truck driver who was high on marijuana and an anti-anxiety medication and slammed head-on into a church bus, NTSB found. Video shot by another driver showed the pickup repeatedly veering onto the shoulder and across the double-yellow line for 15 minutes.
“When you use impairing substances, including alcohol, you do gamble, you gamble with lives,” said NTSB Chairman Robert Sumwalt. “And that’s what happened.”
While test results for drugs aren’t consistent across jurisdictions — an issue the NTSB is asking safety regulators to address — available evidence shows a substantial increase in drugged-driving deaths as opiate use soars and marijuana has become legal in multiple states.
‘Seem to have an epidemic here’
Out of those drivers who died in accidents in 2006 and were tested for drugs, 30% were positive, according to NTSB. That number jumped to 46% in 2015. In random roadside testing, more than 22% of drivers showed evidence of drug use, according to NHTSA data.
“We really seem to have an epidemic here,” NTSB board member Bruce Landsberg said.
“The pick-up truck driver in this crash made terrible choices with tragic consequences,” Sumwalt said. “But the rising tide of drug-impaired driving did not begin with this driver, and it will not end with him. Law enforcement needs additional tools and advanced training to detect impaired drivers before they crash, regardless of the impairing drug they’re using.”
Police need better training on how to spot drivers who may be impaired and “oral fluid” drug tests that police can use after pulling people over, the NTSB found. The safety agency called on NHTSA, which helps oversee highway safety standards, to create specifications for such a test so it can be applied consistently across states.
No uniform national data
NHTSA has been attempting to address the issue. Agency ad campaigns to discourage drunk-driving began addressing drug-impaired driving for the first time in August and the agency has held public meetings on the issue in Seattle, Baltimore and Nashville.
Deputy Administrator Heidi King said earlier this month that, while there’s no uniform national data on the true scope of drugged-driving, the evidence available shows it’s a growing problem. Roadside testing by NHTSA in recent years showed an uptick in drivers with substances in their system, such as marijuana, and a rise of mixing drugs with alcohol.
“There’s not one uniform completely robust collection of information yet, but all of the information supports the need for action,” King said.
The U.S. Department of Transportation’s National Highway Traffic Safety Administration announced this week that 2017 highway fatality numbers are down following two consecutive years of large increases. There were 673 fewer motor vehicle crash fatalities in 2017 than 2016.
In addition, preliminary estimates for the first six months of 2018 appear to show that this downward trend continues into this year.
Dangerous actions continue, emerging trend
“Dangerous actions such as speeding, distracted driving, and driving under the influence are still putting many Americans, their families and those they share the road with at risk,” said NHTSA Deputy Administrator Heidi R. King. “Additionally, we must address the emerging trend of drug-impaired driving to ensure we are reducing traffic fatalities and keeping our roadways safe for the traveling public.”
The 1.8% decrease from 2016 to 2017 compares to the 6.5% increase from 2015 to 2016 and the 8.4% increase from 2014 and 2015.
Proper home maintenance requires constant vigilance.
Chimney fires account for 75% of home heating fires, meaning homeowners should actively monitor their chimneys.
Nearly all residential fires originating in the chimney are preventable.
Chimneys, in particular, require upkeep. A chimney that is dirty, blocked or in disrepair can inhibit proper venting of smoke up the flue, and can also cause a chimney fire.
Homeowners looking to avoid damage to their property and increased premiums should prepare for fires by checking their smoke alarms and updating their emergency plan.
The Chimney Safety Institute of America recommends looking for these signs of a pending chimney fire: a loud cracking and popping noise; a lot of dense smoke; or an intense, hot smell.
