Ontario students more likely to drive after consuming cannabis than alcohol

Poll of 1,161 Ontario students shows attitudes toward cannabis differ from alcohol, creating potentially risky and dangerous driving behavior

(Press-News.org) Poll of 1,161 Ontario students shows attitudes toward cannabis differ from alcohol, creating potentially risky and dangerous driving behaviour

Ontario students are more likely to get behind the wheel of a vehicle after smoking cannabis than drinking alcohol, a new study from researchers at the University of Ottawa's Faculty of Medicine has revealed.

The study, published in Preventive Medicine, found 10 percent of licensed Ontario high school students reported driving within an hour of cannabis use. Driving after drinking alcohol was much less prevalent, with 3.5 percent of students doing so.

The study, led by master's student Nathan Cantor, found that students who favour cannabis legislation and perceive cannabis to be less risky were more likely to report driving after cannabis use. The study found that graduated licencing programs tended to sway behaviours with students holding a G2 licence four times more likely to report driving after cannabis use compared to those with a G1 licence.

"This work reveals that Ontario adolescents perceive cannabis to be less risky than alcohol, and this perception affects other risky behaviours," says principal investigator Dr. Ian Colman, a Full Professor in the School of Epidemiology and Public Health. "The reason this is important is that it suggests that educating adolescents about the risks of cannabis use may be effective in reducing the dangerous practice of driving after cannabis use."

"We need to debunk the myth that cannabis use does not impair drivers," says Cantor, lead author of the study whose data originates from the period prior to the legalization of recreational cannabis in Canada.

"There's a good evidence base that shows acute cannabis consumption is associated with an increased risk of motor vehicle crash, especially for fatal collisions. This association is likely even greater in adolescents - this population has less driving experience, and proportionally represent a higher burden of motor vehicle crashes."

The study polled 1,161 students with valid driver's license about their driving behaviors, drug use, and attitudes regarding cannabis use as part of the 2017 Ontario Student Health and Drug Use Survey. The authors note the prevalence of cannabis-impaired driving should be continuously monitored moving forwards.

Political variables carried more weight than healthcare in government response to COVID-19

2021-06-22
BINGHAMTON, N.Y. -- Political institutions such as the timing of elections and presidentialism had a larger influence on COVID-19 strategies than the institutions organizing national healthcare, according to a research team led by a professor at Binghamton University, State University of New York. Olga Shvetsova, a political scientist at Binghamton University, and fellow researchers explored policy strategies on public health by the federal incumbents worldwide. Specifically, they looked at whether national incumbents led the charge as the pandemic unfolded ...

Not all dietary proteins are created equal

2021-06-22
Dietary protein is needed to supply essential amino acids for the synthesis of the structural and functional components of living cells. Thus, food protein quantity and quality are both essential for good health. The 2020-2025 Dietary Guidelines for Americans (DGAs) published an "ounce equivalents" recommendation to help consumers meet protein requirements with a variety of protein food sources. For example, the DGAs present a variety of "ounce equivalents" in the protein food groups stating that 1 ounce of meat is equivalent to 1 cooked egg, ¼ cup of red kidney beans, 1 tablespoon of peanut butter, 2 ounces of tofu, ...

Study finds common protein in blood enables human fertilization and fighting infection

2021-06-22
Irvine, CA - June 22, 2021 - A new University of California, Irvine-led study reveals albumin (Alb), among the most abundant proteins in the body, activates a proton channel (hHv1), also widespread in the body, giving sperm the ability to penetrate and fertilize an egg, and allowing white blood cells to secrete large amounts of inflammatory mediators to fight infection. The study titled, "Direct activation of the proton channel by albumin leads to human sperm capacitation and sustained release of inflammatory mediators by neutrophils," was published today in Nature Communications. Researchers examined the physiological ...

New machine learning methods could improve environmental predictions
2021-06-22
Machine learning algorithms do a lot for us every day--send unwanted email to our spam folder, warn us if our car is about to back into something, and give us recommendations on what TV show to watch next. Now, we are increasingly using these same algorithms to make environmental predictions for us. A team of researchers from the University of Minnesota, University of Pittsburgh, and U.S. Geological Survey recently published a END ...

SFRP2 and PD-1 immunotherapy combination halts osteosarcoma metastasis in model

SFRP2 and PD-1 immunotherapy combination halts osteosarcoma metastasis in model
2021-06-22
In a cancer that has not seen new targeted therapies for over 20 years, MUSC Hollings Cancer Center researcher and oncologist Nancy Klauber-DeMore, M.D., is pioneering new discoveries. Using a combination of personal passion and expertise, Klauber-DeMore shifted her knowledge of the pro-angiogenic protein SFRP2 in breast cancer to address the lack of treatment options for patients with aggressive metastatic osteosarcoma. The results of the combination treatment with SFRP2 and PD-1 antibodies in a preclinical model were published in Cancers. Osteosarcoma expert William Tap, M.D., chief of the Sarcoma Medical Oncology Service at Memorial Sloan Kettering ...

Asymmetry in CO2 emissions and removals could skew climate targets: SFU research

2021-06-22
Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth's atmosphere are not equal to the climate changes from deliberate CO2 removals--and assuming such a balance could lead to different climate outcomes that may skew climate targets, according to new Simon Fraser University-led research. "Because of the complexity of the Earth's system, things are not as simple as "one ton of CO2 in, equals one ton of CO2 out," says Kirsten Zickfeld, a distinguished professor of climate science in SFU's Department of Geography, and lead author of a new paper published ...

Pandemic shift to home working could create UK tax crisis

2021-06-22
The shift to home working brought about by the pandemic could cost the UK economy up to £32bn a year in lost personal income tax. Highly paid workers who live abroad but work in the UK will pay their income tax in their country of residence, rather than to HMRC - which researchers say could cost billions each year. This new mobility of the workforce can also affect where corporate income tax is paid and value created, as well as VAT and where goods and services are purchased. Professor Rita de la Feria, Chair in Tax Law in the University of Leeds' School of Law, co-led the new research with Dr Giorgia Maffini, Tax Policy expert, at PWC, ...

It's true: Stress does turn hair gray (and it's reversible)

2021-06-22
Legend has it that Marie Antoinette's hair turned gray overnight just before her beheading in 1791. Though the legend is inaccurate--hair that has already grown out of the follicle does not change color--a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons is the first to offer quantitative evidence linking psychological stress to graying hair in people. And while it may seem intuitive that stress can accelerate graying, the researchers were surprised to discover that hair color can be restored when stress is eliminated, a finding that contrasts with a recent study in mice that suggested that stressed-induced gray hairs are permanent. The ...

Some seafloor microbes can take the heat: And heres what they eat
2021-06-22
WOODS HOLE, Mass. -- It's cold in the depths of the world's oceans; most of the seafloor is at a chilly 4°C. Not so the seafloor of Guaymas Basin in the Gulf of California. Here, tectonic plates drift apart and heat from Earth's interior can rise up -- so far up that it bakes large areas of the seafloor sediments, turning buried organic matter into methane and other energy-rich compounds. What kinds of organisms thrive in this oceanic hotspot? In two new studies, MBL Assistant Scientist END ...

Investigating a better treatment sequence for esophageal cancer

2021-06-22
Looking for better ways to treat patients with esophageal cancer, University of Colorado Cancer Center member Martin McCarter, MD, is investigating whether a new treatment sequence will result in better outcomes. As they await the results of a group of clinical trials -- including one at the CU Cancer Center -- McCarter and other University of Colorado researchers (led by surgery resident Bobby Torphy, MD, PhD) looked at data from the National Cancer Database to see if they could identify other patients who have undergone the new sequence, and what the outcomes for those patients were. The group published a paper in the Annals of Surgical Oncology in April ...
