Does Marijuana Affect Driving Skills? – Verywell Mind

Users often drink alcohol while ingesting marijuana. While research generally suggests additive or even multiplicative effects with alcohol, some studies suggest effects are no different than alcohol alone. Alcohol likely reduces compensation skills marijuana users otherwise may employ. There is little research on marijuana use with other drugs other than alcohol.

It’s more than just dangerous, though. Marijuana impaired driving will likely get you into legal trouble. And that’s only one possible issue if you’re caught high or driving with weed. Here’s everything you need to know about a marijuana-related DUI. The problem with driving while high on weed is that it impairs a person’s judgment behind the wheel.

However, in most cases, drivers suffer from significant reductions in their coordination abilities. Plus, their reaction time slows, which can be particularly dangerous when a railroad crossing, stoplight or another obstacle lays ahead. In most cases, a person’s ability to drive will be impaired for one to two hours after smoking weed.

But the National Institute of Drug Abuse has found that smoking weed before driving can more than double the risk of an accident, depending on how much a person ingests. Not only does driving under the influence of marijuana put you and others in danger, but it means you could get in trouble with the law.

But you can be sure that driving after smoking weed — and getting caught — will get you in trouble. In general, states class driving under the influence of weed as either a DWI or DUI law violation. The latter stands for driving under the influence, while the former means driving while impaired.

Driving While High: What Are The Laws In Canada?

For instance, particular places have laws that regulate the level of THC a driver can have in their system. THC, of course, is the psychoactive compound in marijuana. So, a driver could face a per se marijuana DUI if authorities take a blood sample to prove THC was present — and, in some places, over the legal limit.

In other states, there’s an impairment DUI, which you could face even without blood tests to prove the presence of THC. Prosecutors could argue their case successfully if you fail a field sobriety test, for example. Notably strange behaviour, unsafe driving or slurring your speech can also qualify you for an impairment DUI. In states that have legalized marijuana, you can drive with weed in the car.

For instance, if you have to be 18 to smoke, then you have to be 18 to have weed in your car. Laws in these states stipulate how you can behave while driving, too. They function like open container laws with alcohol, regulating a smoker’s behaviour while they operate a motor vehicle.

First-timers might get off after paying a small fine and completing a safe-driving class. Driving under the influence of marijuana puts you and everyone else on the road in harm’s way. Your safest bet — and the best way to avoid getting in legal trouble — is to stay out of your car if and when you smoke.

Is It Okay To Smoke Weed And Drive? – Vice

People using a driving simulator showed no signs of impairment a day after they smoked cannabis, though they still tested positive for THC, its main psychoactive component, a recently published paper says. The research has implications for laws and workplace rules that require no trace of THC, which Scott Macdonald, a retired professor at the University of Victoria, calls “not scientific.”LISTEN: Drex speaks with lawyer Kyla Lee about the study on The Shift Story continues below advertisement “I consider it one of the biggest myths about cannabis, that there are 24-hour hangover effects that are measurable,” he said.

“Most young people drive and have a day to day responsibilities like school and work, so when we have data demonstrating that individuals would test over the limits 24 and 48 hours after use, this does little to make our roads safer from impaired drivers and deserves a reassessment,” she wrote in an exchange of e-mails.“Driving is a privilege, but at the same time, cannabis is legal now, and young people over the age of access should be able to consume on the weekend and drive one full day later to work or school without risking a DUI charge.”Across Canada, some police forces have effectively banned cannabis for their own members.

(Since THC can be detected up to 28 days after consumption, these policies are more or less the same.)Police unions in Toronto and Calgary objected to the policy when it was announced, with Toronto’s calling it “ill-contrived” and “arbitrary,” and Calgary’s saying that members had said they were “certainly not really happy with the idea of my employer telling me what I can and cannot do with a legal substance on my own time.’”I think [28-day bans] are excessive and not scientifically based, especially now that cannabis is legal,” Macdonald says.

The military allows cannabis use at some times for some members, depending on their jobs. Some, like divers, aircrew, members of submarine crews and drone operators, have a 28-day prohibition similar to the more restrictive police forces.“Many jobs — typically those which are safety-sensitive — have adopted a zero-tolerance policy, but as cannabis becomes more integrated into society, we’re going to need to consider policies that are reflective of this change and embrace a better understanding of cannabis and its effects,” Valleriani wrote.

Macdonald was not involved with it. During the study, a placebo group was given joints with no THC to smoke, but it turned out that participants were well aware of whether they had consumed THC or not, with over 90 percent in both groups accurately saying what group they were in.
